The Challenges of Seeded vs. Seedless Cannabis
As both drug cannabis and hemp cultivation proliferate, agronomic challenges lurk on the horizon. But there are solutions.
Temperate regions of Australia produce low-THC cannabis crops grown for their edible seeds and seed oil. Hemp seed crops release clouds of male pollen grains, each with the potential to fertilize a female flower and form a seed. The male pollen plants then wither and die.
Today, a multitude of cannabis seed companies are producing more seeds than ever, and now that laws are changing, more and more cannabis crops are being grown outdoors from seed.
Broadacre (farms that produce crops on a large scale) CBD producers are leading the return to growing crops from seed. Auto-flowering THC and CBD varieties are gaining popularity (especially in regions exceeding 40° latitude north or south) where summer days are too long to induce flowering in most cultivars.
But the growing of seed crops can cause problems. Put simply, the airborne pollen from seed crops poses a serious threat to the much more lucrative business of growing seedless drug cannabis flowers.
Morocco: En Route to All-Female (Seedless) Crop Production
Morocco, where crops destined for hashish production are seeded, is on a steady path toward all-female seedless crop production. The popularity of feminized seeds, which produce only female plants, has grown exponentially, yet nearly all modern Moroccan drug crops still do not start from these because many growers continue to sow seeds that they harvest (rather than purchasing new seeds), and crops grown from these seeds are half male and half female. Pollen fills the air in mid-summer, and by autumn every female plant is full of seeds. (When females are pollinated, their flower growth is reduced, and the seeds produced are undesirable for end consumers.) Morocco’s future of not harvesting seeds is clearly on the horizon as awareness amongst farmers and widespread availability of less expensive female seed are slowly becoming reality.

Biology Meets Agronomics
Most plants produce flowers bearing both male and female sexual organs, and the majority of these are pollinated by various animals ranging from insects to bats. In natural settings, Cannabis plants present an exception to the norm, with millions of pollen grains borne on male plants that release their genetic potential into the breezes. Those pollen grains that complete their reproductive journey land on the receptive ovule-containing flowers borne on female plants and fertilize them, the seeds maturing a few weeks later. Individual male plants die within a few weeks, leaving the remaining pollinated female plants to mature their precious seeds (the next generation) without competition for water, nutrients and sunlight.
In another exception to the norm, separation of the sexes is the key to horticultural cannabis flower production. Both THC and CBD drug cannabis crops are grown without seeds. The sinsemilla (seedless) method is commonly used to enhance the production of secondary metabolite target compounds such as THC, CBD and aromatic terpenes. When seedless Cannabis is grown for drug production, any seeds are undesirable and drastically lower the value of the dried flowers. Early sinsemilla growers realized that they could simply remove all male plants so no seeds formed, and their precious females would develop much larger and more potent flowers. Female plants with desirable traits were vegetatively reproduced to multiply the clones in common production today, and there are no longer troublesome male plants in most modern drug crops.
We believe seeds producing all-female crops will be widely used for broadacre THC and CBD production in the near future. Why grow any males when you can grow only females, and why keep mothers and make cuttings when you can more easily, efficiently and cheaply sow seeds that are essentially a female cutting in seed form?
This sounds like a perfect scenario. What could possibly go wrong?
What Is Industrial Hemp?
Today’s common concept of “industrial hemp” crosses regulatory boundaries between traditional hemp (grown for its fiber and/or seeds) and drug cannabis. According to the Agriculture Improvement Act of 2018 (commonly referred to as the U.S. Farm Bill), any Cannabis plant (or cannabis product) containing less than 0.3 percent THC (with no limits on CBD content) is legally classified as “industrial hemp” no matter whether its end use is for fiber, seed and/or drugs. A more accurate term for high-CBD cannabis is “medicinal hemp” as it reflects both its end use and its low THC content.
Significant CBD levels (commonly 2 percent to 5 percent dry weight) are extracted from the flowers of hemp fiber and seed cultivars grown in many regions of Europe and China. Much of this CBD yield comes from multi-product hemp crops also yielding fiber and seed commodities. Across North America, CBD is largely extracted from modern, high-CBD drug cultivars that are much more closely related genetically to modern sinsemilla hybrid drug varieties than they are to hemp fiber and seed cultivars.
Enter Traditional ‘Industrial’ Hemp
In Europe and North America, hemp fiber crops have traditionally been harvested upon reaching technical maturity when the male plants begin to shed pollen. In eastern Asia, hemp fiber crops destined for fine textile production are harvested before they flower, and therefore no pollen or seed is produced. No flowers, no pollen and no problems. The timing of a fiber crop harvest—either before or after it releases pollen—determines whether it poses a threat to neighboring sinsemilla cannabis growers. Depending on cropping techniques, fiber hemp production can be compatible anywhere. The real issue is not about fiber hemp production, but seedless drug cultivation. However, the situation differs with hemp seed crops.
Hemp-seed crops are grown specifically for seeds sold primarily to the food and body-care industries. Hemp seed and seed oil are more in demand than at any other time in recent history, and the profitable growing of hemp seed is increasing at suitable temperate latitudes worldwide. Based on their common environmental needs, seedless drug cannabis thrives in the same agricultural niches as hemp seed crops, and this can lead to competition between these agronomically incompatible crops.
Long-distance Cannabis pollen transport is well-documented. A single male Cannabis plant can produce millions of pollen grains that are easily carried on the wind. Each summer, allergenic pollen traps installed along the Mediterranean coast of southern Spain collect Cannabis pollen that drifts across 100 miles of open sea from hashish fields in the Rif Mountains of Morocco.
Field-grown hemp seed crops are agronomically and economically incompatible with drug cannabis crops, and growing them within the range of pollen travel will likely result in conflicts. Even cannabis plants grown in greenhouses and grow rooms can become fertilized by pollen that enters through the ventilation system. It is of note that during the early days of industrial hemp cultivation in the Netherlands several indoor and glasshouse sinsemilla growers reported finding seeds in their normally seedless crops. (Tip: High efficiency particulate air (HEPA) filters effectively remove pollen from air intakes in sealed grow rooms.)
In the sinsemilla setting of zero tolerance for seeds, long-range pollen drift, especially outdoors, sounds frightening. Reactionary voices within the cannabis community have raised the alarm, but is there a real threat? How are the cropping strategies of growing seeded hemp cultivars for their CBD content versus growing seedless drug varieties for THC and/or CBD content playing out across North America and worldwide?
HempFlax BV farmers in Romania harvest hemp fiber, hemp seed and CBD from the same standing crop. Multi-cropping strategies are the most economically viable for broadacre cannabis commodity farming.
International Precedents and Lessons
In response to increased market demand for both hemp seeds and CBD, traditional hemp cultivars’ flowers are now commonly grown to produce both CBD and seed. Hemp stalks are harvested for their economically valuable fiber from both the male and female plants, while female flowers produce economically valuable compounds such as CBD, THC and aromatic terpenes as well as seed. Broken flowers remain after threshing hemp seeds. Until recently, this CBD-rich waste was burned in the fields. Now, CBD is extracted from the flower biomass. Several hemp cultivars contain sufficient amounts of CBD to make extraction profitable.
We perceive the most lucrative agronomic model to be triple cropping an existing approved (low THC) industrial hemp cultivar for fiber, seed and CBD. HempFlax BV, a hemp cultivation and processing company with cultivation sites in the Netherlands, Germany and Romania, harvests all three products from the same standing crop. This lucrative cropping strategy allows a farmer to make agronomic decisions based on three commodity markets—fiber, food and drug—and we predict will prevail in the near future among progressive farmers worldwide.
China and Romania are traditional hemp farming regions without commercial seedless drug cannabis production. Manitoba farmers have dominated North American hemp grain seed production for 20 years and have established Manitoba as a hemp seed producing region. Few outdoor sinsemilla growers would attempt to establish production there. Rather, drug cannabis is more often grown indoors in urban areas, and in glasshouses and outdoors in regions without hemp seed crops. To that end, conflicts are rare, but could still arise.
In most drug cannabis producing regions (e.g., Colombia and Mexico, as well as the Caribbean, Africa and Southeast Asia) crops are grown seedless to increase the flowers’ potency. It would be unwise to attempt growing seeded crops in these regions. In all these examples a pairing of local traditions with economic factors determines whether Cannabis crops are grown with or without seeds.
Several of the aforementioned agricultural business models could prove economically viable in any given region, but many are not mutually compatible. The agricultural differences among broadacre, greenhouse and indoor production create an economically segregated terrain where few conflicts have yet to arise. However, conflicts will undoubtedly arise unless specific cannabis growing regions become set aside for female-only growing of seedless drug crops.
North American Constraints
In the face of steadily expanding seedless drug crop acreage bolstered by supportive legislation across America, will there remain anywhere for hemp grain seed crops to make their long-awaited comeback? Will the U.S. always rely on Canada and China for healthy hemp seed products?
The expanding range of Farm Bill hemp (high-CBD seedless flower) production in 2018 reached 23 states. Colorado and Montana, leaders in U.S. hemp production, each grew more than 20,000 acres, followed by Kentucky and Oregon with around 7,000 acres each, and Tennessee, North Carolina, North Dakota, New York, Nevada, Wisconsin and Vermont had from 1,000 to more than 3,000 acres under licensed cultivation. More than 78,000 acres of Farm Bill “hemp” were grown in 2018 nearly, tripling the less than 26,000 acres grown in 2017.
Now, private citizens as well as agricultural entities across North America are increasingly allowed to grow both industrial hemp (including hemp grain seed crops) as well as seedless drug cannabis for medical and adult use. In some areas this situation sets the stage for potential conflicts until industry self-regulation and enlightened agricultural policies take effect. In the meantime, most regions appear to offer opportunities for everyone.
However, the situation is becoming increasingly convoluted. The U.S. landscape is a complex puzzle of differing jurisdictions, each with its own evolving cannabis scenarios and range of regulatory solutions. Until the advent of the CBD industry, industrial hemp cultivation held little attraction in most regions of the U.S., and largely due to prohibition, most seedless drug cannabis was grown either in remote rural or insular urban settings isolated from any hemp pollen. Many newly cannabis-tolerant jurisdictions may allow Cannabis plants to be grown for whatever end use someone might choose—be it fiber, seed and/or drug.
In many regions across North America, sinsemilla growers arrived decades earlier than the recently arrived “hemp” growers. North American sinsemilla growers pioneered drug cannabis cultivation and established their turfs long ago, largely in agriculturally marginal rural areas not well-suited to broadacre hemp fiber and seed production. California presents several cases in point.
Sparsely populated rural regions of Northern California have been the primary producers of sinsemilla since the 1960s, and since the 1980s indoor, artificial-light growing has become increasingly popular in more urban regions with access to the electrical grid. The established agricultural precedent in both scenarios is drug cannabis production. So far, industrial hemp and hemp seed crops have had little, if any, effect. It is really up to the growers of seedless high-THC and high-CBD drug crops to defend their turf (especially outdoor cultivation, which is common in California and expanding elsewhere) from the potential pollen threat of seeded crops.
Seeds or Seedless: What’s the (End) Use?
Seed-grown cultivars will always remain popular for broadacre farming of hemp seed and fiber crops as well as cannabinoid and terpenoid crops. We predict that consistently improving newly developed clones will feed the connoisseur cannabis (drug) dry flower market, while broadacre cultivation from seed will supply the majority of future market demand for extract-based products worldwide.
On the West Coast, state cannabis grower associations are striving to establish sinsemilla production regions based on climate and terroir similar to the appellation system used in wine branding. These groups have grown organically from illicit rural grower communities and provide good examples of self-regulation of our industry from within by a group of peers. Appellation membership will likely require qualified farmers to grow only female plants from cuttings, and the sowing of seeds (a possible source of male plants and contaminating pollen) will be strictly controlled.
Both industrial and medical hemp crops are most profitably produced under broadacre agriculture, while sinsemilla flower crops are most profitably produced under glass. California’s Sacramento, San Joaquin, Imperial and Salinas valleys present examples of regions where potentially conflicting business models may clash. Many growers in these traditionally broadacre farm and orchard regions have switched to glasshouse production of vegetables, bedding and house plants, and cut flowers. Sinsemilla flower growers will move into regions where glasshouses are readily available, and local regulations usually stipulate that existing glasshouse infrastructure must be utilized. This places seedless growers near neighboring broadacre farms where it is also economically feasible to grow fiber and seed hemp.
Southern California provides an even more dynamic terrain. As urban areas grow, cultivators occupy former farmlands that still border active agricultural zones. And, traditional broadacre farming regions that previously grew few if any sinsemilla or hemp crops are now open to the growing of either one or both.
These scenarios exemplify the need for agricultural authorities to take responsibility for local regulation of their cannabis industries before conflicts between growers arise. There are few established historical and agricultural precedents for either sinsemilla or hemp growing in prime agricultural regions. These areas produce many crops profitably, and as with other crops, are where the future of commercial cannabis production for many different products will be focused.
Given that sinsemilla (seedless) growers have zero tolerance for seeds in their flowers, buffer zones around pollen-producing crops should start with at least a 10-mile radius. Safe distances should be increased to up to 30 miles or more if the pollen source is a broadacre grain seed field or if seedless crops are established down wind of seeded crops. Agriculture officials can make “pollen risk” assessments and generate pollen maps for mixed cropping regions where both seedless and seeded crops may be grown. Local cannabis appellations can enforce their own in-house rules to ensure that members remain compliant by growing only female cuttings.
In addition to industry self-regulation, agricultural policies concerning cannabis cultivation will become agriculture department initiatives, influencing state and eventually federal legislation to delineate which regions are reserved for broadacre hemp seed, hemp fiber and/or drug production from seeded plants. We expect that farming regions where broadacre agriculture is already the norm and where fewer sinsemilla growers operate than many other regions will be where hemp seed and fiber crops will be grown. Sinsemilla growers simply won’t settle in these regions, and the few who live there already will likely move.
Regulatory allowances must also be made for certain branches of our industry. Drug cannabis breeders rely on sowing seeds in their search for novel traits, and cannabis seed companies rely on carefully controlled pollinations to produce consistent offspring. The threat of stray pollen is minimal, and seed companies should be allowed to responsibly produce small amounts of pollen for research purposes.
Many suffered and lives were lost in disputes between frontier cattle and sheep grazers over the best use of Midwestern grazing pastures. Let’s hope our cannabis community will have the foresight to avoid predictable calamities. There are many economic factors in the mix, and guidelines for establishing enlightened agricultural policies in each region should be established soon before push comes to shove. In the end, it is really about growers gaining deeper awareness of their local situation and doing their best to be good neighbors.
How will various jurisdictions with differing constituencies and priorities create equitable policies for the control of stray cannabis pollen in sinsemilla-only areas?
People are quirky, and there will always be a few individuals who will grow fiber or seed hemp in regions where drug crops are commonly grown, and there will be others who try to grow seedless cannabis flowers where seed hemp is well established, but these will be exceptions to the local norms. Across North America, effective and fair regulation of our burgeoning cannabis industry will largely rely on understanding which branch of our industry was established in each region first, and whether a precedent exists for its continuation; ultimately, policy decisions will be based on which end use offers the most income (including compliance costs, local trade, employment and taxes) to local and state jurisdictions.
Local, state and federal agriculture organizations should ultimately control cannabis licensing and permitting, first in local jurisdictions and eventually nationwide. Agricultural officials must take stock of regional conditions and become sensitive to the unfolding cannabis industry and determine the traditional basis for cannabis economics in their region. If sinsemilla growers have contributed to the economic viability of their local economy, albeit illegally, then they should be invited to have a strong voice in determining future cannabis policies and regulations.

Everything that you need to know about smoking seedy weed
It can happen to the best of us, especially when it comes to outdoor crops, as it really doesn’t take much for one lonely male to pollinate hundreds of females within a several mile-wide radius. Cannabis seeds can appear when we least expect them to, and that’s why it’s so extremely common to get a crop or a bag from your local dispensary that has these annoying pieces scattered throughout the flower.
This is one of the reasons why so many cultivators take such strict steps to avoid contamination by wearing full-body gear and even PPE that is completely sanitary and disposable, but once you’re past the point of no return, and left with a pile of weed seeds in your buds, there are only so many options. You can toss it, and lose out on all of that hard work, or you could process the plant materials along with the marijuana seeds into oil or some other concentrate, but for those who have invested their last few dollars, or prefer the enjoyment that pure flowers can offer, one question remains.
Many people wonder if cannabis is safe to smoke when it’s full of a bunch of seeds, and if it is, in fact, safe as far as the lungs are concerned, whether or not there are any other potentially adverse effects that they should be privy to. Since this is such a common problem, we feel the need to answer these questions in-depth, so that consumers know what they’re getting into when they’re inevitably faced with this scenario.
Is it risky for your health to smoke cannabis seeds?
Marijuana seeds consist of completely non-toxic plant matter, so they are entirely safe, as far as we can tell, to smoke along with flower, which means that if you find them in a bag, they aren’t going to make you sick, but unfortunately that doesn’t necessarily translate to a truly enjoyable experience, as you will soon find out.
Adverse effects on taste
Cannabis seeds are incredibly annoying when they get lodged in a joint roll or stuck in your grinder, but the absolute worst thing about them is that they taste terrible when they’re smoked, which can completely ruin the normally delicious flavors of your weed. This might sound strange at first, after all, the materials all come from the very same plant, but those yummy trichomes and terpenes that you’d normally bask in simply don’t exist in weed seeds.
Unfortunately, what they do have is a whole lot of fibrous material, so when these bits of the cannabis plant are burnt, they leave behind a distinctive and shocking level of taste that many compare to charred popcorn. It’s certainly not going to be enough to hurt you, but they could leave you coughing or with a burnt tongue feeling, and both of those things can significantly impact the flavor of your herb in a bad way.
If you’re one of the truly unlucky ones that have a crop that gets hit really hard with a foreign dose of pollen, then the weed seeds that develop could seriously reduce the quality of your cannabis, and it’s not just the taste that is impacted. Since cannabis seeds are a fair-sized, they take up a whole lot of room and add weight that otherwise wouldn’t be there, which results in a double whammy as far as potency is concerned because they also don’t contribute any cannabinoids to the harvest.
That’s right, those heavy, irritating cannabis seeds might look pretty and be attached to a fully matured plant, but they have absolutely nothing in common with the flower materials that surround them. To put it more simply, if you had one gram of two identical plants, with one that had been pollinated, the bud would weigh more, but it would have far less for cannabinoids like THC or CBD, which are the elements that influence how you feel right after taking a bit hit off of a joint.
In their absence, your buds won’t be nearly as strong or effective, which means that you will need to smoke way more to get the same results, so you’re also going to find that you go through a whole lot more weed than you’re probably used to with better quality product, and you still might not be satisfied once all is said and done. Now, of course, this isn’t the case with all seedy cannabis as there are various levels of seed production to consider, but it will greatly reduce the potency of what could have been a stellar harvest.
So now that you know what smoking seedy weed can do, it’s time to highlight one of the only real dangers of applying heat to cannabis seeds. These little balls seem nearly indestructible, and carry a wood-like texture that might have you believe that they’d burn away slowly just like a chunk of wood, but the way it works is much more like popcorn kernels which explode to produce the light and fluffy snack.
Sadly, marijuana seeds aren’t nearly as fun to watch heat up, especially when they’re in a joint or well-packed bowl, because they can and often will explode, and that can result in flying hot coals and joints that get ripped wide open due to the incredible amount of pressure. These things might not be overly dangerous, but they are something that every cannabis consumer should be aware of, as they tend to hit sensitive areas like the eyes or mouth, which can be quite painful.
The best ways to deal with weed seeds in your flower
Now that you know everything there is to know about smoking seedy cannabis, it’s time for us to discuss some of the different ways that you can choose to deal with the problem. Some are certainly more effective than others. However, all three of these solutions will work to at least reduce the effects that cannabis seeds can have on the experience of getting high.
1. Remove them manually
If you have a really bad case of seedy weed, then this might not be the best option, as it can be time-consuming to do, and even if you do manage to remove every single one, they will leave behind dried up shells that will still produce that lingering taste we talked about earlier. The best way to use this is by hand, using your fingers to gently shuffle through the bud and pinch any seed casings which should make them fall right out.
2. Make the flowers into a cannabis concentrate
If removing the marijuana seeds sounds like way too much work, and you’re open to trying or using other more potent cannabis concentrates like cannabis oil or cannabutter, then the best choice might be to toss the whole pile into the solution. Cannabis seeds might taste awful when they’re smoked, but that quality doesn’t carry over when they’re included in plant materials that are used to make concentrates. They strain right out, and you’re left with only the best element, which is why this is a preferred method of dealing with seedy weed for many cannabis consumers.
3. Use an electric grinder to break them down
If you aren’t willing to budge on the idea of a freshly packed bowl, and you’re really not interested in dedicating a whole bunch of time to the removal of the cannabis seeds, then you are left with only one option other than tossing it out, which would be a waste. Using an electric grinder will help you to avoid clogged or broken manual grinder, and it will reduce the cannabis seeds into dust so that you won’t see any sparks flying that may cause burns when you smoke them, but unfortunately, this method isn’t typically ideal, because it still leaves the strong taste that can ruin the natural flavors of your buds.
7 tips to increase the potency of cannabis buds
The same cannabis seeds, grown by two different growers can produce dramatically different THC levels. Grow environment, the absence or presence of several common stress factors and the cannabis genetics will largely dictate the total cannabinoid content as well as terpene levels and yield. There are some tried and tested methods to improve the potency of cannabis buds. It’s equally important to avoid some common pitfalls made by less experienced home growers. Our top tips are below.
Best ways to improve homegrown cannabis potency
Some of the best ways to increase the potency of homegrown cannabis may require you to change existing grow room habits or equipment. If investments are required, then remember that a high-value crop like cannabis will soon repay the grower with harvests that will reach new levels of potency.
1. Ensure optimal LED lighting levels and exposure
Indoor homegrown cannabis
A good quality LED will last years and suffer very little noticeable loss of intensity even after several years of use. Buy wisely from a competent manufacturer and they will supply a chart showing the expected PPFD levels at various hanging heights above the canopy.
Outdoor homegrown cannabis
Some licensed outdoor growers do position greenhouse-style LED light bars around their prized outdoor plants during bloom to maximise potency. Though in reality few outdoor growers can implement such luxuries. In reality the best an outdoor grower can do is to cut back surrounding vegetation so their cannabis plants can enjoy all-day sunshine.
Greenhouse homegrown cannabis
Supplemental greenhouse LED light bars are highly recommended for any greenhouse cannabis grower. Fitted with integrated light sensors, the LED bars will automatically adjust their brightness according to ambient natural light levels. You can expect to increase the potency of cannabis buds as well as improve yields.
2. Choose cannabis seeds with the highest-THC potential
Even the world’s best cannabis growers can’t get high potency buds from genetics with low-THC or medium-THC potential. Note that some growers deliberately avoid the highest THC strains if they simply feel uncomfortable with the most potent cannabis buds. Thats why many cannabis seed suppliers offer strains with low, medium and high THC potential.
Dutch Passion have grouped together the top 15 (or so) strongest feminised seeds and autoflower seeds into a special High-THC seed collection. If you are only interested in growing the very strongest Dutch Passion strains click below!
Highest-THC feminised photoperiod cannabis seeds
Sugar Bomb Punch®
Sugar Bomb Punch is a cannabis cup winning indica strain. She shows great plant-to-plant consistency. In recent lab tests every single Sugar Bomb Punch plants showed THC levels in the 20-25% range.
Mokum’s Tulip is a hybrid cannabis seed with outstanding genetics from Gelato x Sherbet. This strain delivers numbing potency levels, up to and around 25% THC is possible when these elite USA genetics are created with love and care.
Amsterdam Amnesia is a sativa cannabis strain with legendary genetics. The Amnesia high is so powerful many forget what they were doing. If you love an energising and euphoric sativa strain there are few any better!
Highest-THC autoflower cannabis seeds
Auto Skywalker Haze®
Auto Skywalker Haze has hit the headlines for all the right reasons since her release with several independently recorded lab results with 25-30% THC levels. Autoflowering cannabis seeds just don’t get much better than this. Curiously even the feminised seed version of Skywalker Haze can’t yet quite match the same THC levels as the autoflowering version.
Auto Cinderella Jack®
Auto Cinderella Jack is another autoflower seed that has produced 25% THC levels. This hybrid autoflower strain is notably easy to grow in a wide range of conditions with heavy yields and potency levels that are so strong they are recommended only to experienced consumers.
Auto Orange Bud®
Auto Orange Bud uses classic original ‘Orange Bud’ cannabis genetics to deliver a knockout blow in a sweet citrus wrapper. The mouth watering flavours of clementine and citrus fruit fuse with a skunky goodness. Wonderful euphoria follows along with a soaring high.
3. Maintain your plants health from seed to harvest
Ensuring a stable, steady grow environment sounds far easier than it really is. To allow your cannabis plant to thrive you need to ensure she can grow steadily free from stress, environmental battles and pests. Keeping your plant in the nutrient sweet spot with neither over feeding nor underfeeding is a great foundation.
Use of slow release organic nutrients such as those from BioTabs is highly recommended to avoid the yo-yo effect; cycling from over-feeding to under-feeding the plants. Maintaining steady temperatures free from extremes of heat and cold is also another essential.
4. Harvest your cannabis buds at the right time
Home growers often know how they like their cannabis ripening. Many feel that ‘commercial’ cannabis and street weed tends to be harvested a week or two earlier than preferred. Home growers can select the precise moment of cannabis harvest for them.
Our expert guide explains all you need to know about timing your cannabis harvest and how the buds look at various stages from early harvest all the way through to late harvest.
Tip: Many growers believe that adding a couple of days of complete darkness at the end of the bloom period helps their plants to increase resin (and therefore THC) levels.
5. Do not neglect or rush the bud curing process
One of the more overlooked stages of the cannabis bud production process, a good curing maximises the delicious taste and preserves optimum potency levels. Once your buds are perfectly cured you may wish to put them in an air-sealed jar or possibly the freezer where they will remain in peak condition for a year or more.
6. Use a supplemental UVA/UVB light
Many top growers supplement their LED grow light with a UVA/UVB light. These mimic the UV wavelengths seen in natural sunlight and allow the cannabis plants to gain and extra couple of THC percentage points. Terpene content also improves in the presence of UV supplemented light.
7. Try cold conditions in late bloom
Many licensed growers as well as hobby growers are great believers in introducing cool conditions in late bloom, just before harvest. Licensed growers often do this with cold air. This usually requires onsite air-conditioning in order to drop ambient temperatures sufficiently.
The effect is claimed to increase THC and resin levels. Often this will introduce autumnal hues to the buds and leaves. Hobby growers can replicate the effect by adding ice cubes around the stem.
Debunking common myths about homegrown cannabis potency
There is plenty of misinformation about homegrown cannabis potency, and plenty of bad advice too.
Not true. Licensed growers have worked hard on continuous improvement programs that show that small incremental improvements can be made through optimisation of environmental factors. There are some fast, quick wins too – anyone upgrading from HPS to LED will automatically notice new quality levels.
CO2 availability is often a bottleneck that can limit yield rather than potency. The carbon in the carbon dioxide gas is used as a chemical building block for new growth, therefore increasing the CO2 concentrations can improve yield (assuming no other factors are limiting growth). Note that high CO2 levels only make sense with high PPFD levels
Not necessarily! Much depends on the outdoor conditions and the cannabis seeds being used. Whilst it is true that the indoor grower can produce ideal conditions many indoor growers routinely make the same errors (such as over watering and over-feeding, the 2 most common mistakes). A skilled outdoor grower using fine-quality outdoor cannabis seeds may well produce more potent cannabis buds than a less skilled indoor grower using poor genetics and practices.
Definitely not true! In fact Dutch Passion have recently seen autoflower strains producing higher THC levels and higher total cannabinoid levels than their photoperiod siblings. Several of the Dutch Passion autoflower seeds will produce plants capable of THC levels in the 25% range.
Not proven. Many growers feel that a little stress can improve potency. It is perhaps easier to say that bending, cutting, SCROGing, super cropping etc can improve yield by maximising light use.
