What is a Grow Op?

Before we delve into the specifics of planning a grow operation, it is important to establish an understanding of what a growing op actually is. According to Google, a grow operation is an enterprise or facility engaged in the growing and selling of marijuana. Commonly referred to as grow op, grow space or grow room, these facilities can vary in size, requirements and production capacities.

a grow operation is an enterprise or facility engaged in the growing and selling of marijuana.

Although there are all sorts of options for running a marijuana grow operation, they can be broken down into two categories: commercial and residential.

A residential growing op can usually be set up one of two ways. The first is by retrofitting a room in your place of residence. Necessary provisions must be taken into consideration concerning lighting, irrigation and air ventilation. This requires careful research because each residential space comes with a distinct set of challenges.

The second way you can set up a residential marijuana grow up is by purchasing a prefabricated tent which houses the plants. Prefabs are useful because they drastically reduce set up times. They usually come equipped with the necessary furnishings to hang lights and hydroponics systems, as well.

Usually, a commercial grow op is a substantial operation simply because of the grow area it spans. Whether it’s an indoor facility or an outdoor venture, hundreds if not thousands of plants need to be managed. On the other hand, a residential growing op is more manageable and requires less equipment.

Growing Cannabis Indoors

One of the easiest ways to minimize exposure to these factors is by launching an indoor grow operation set up. Growing cannabis indoors requires a secure, enclosed facility that has the necessary space to accommodate windows, doors, walls and a roof. This means you have more control over important circumstances like lighting, temperature and hydroponic systems. It also decreases your chances of having to rely on harmful pesticides to fight invasive insects!

How to Start a Grow Operation

Before taking any actionable steps toward your growing op, it is crucial to be knowledgeable of any specific rules laid out in Michigan marijuana laws. Launching a grow operation prior to obtaining the required licensing can result in fines, as well as other legal action. Because each state has varying regulations relating to the growing and cultivation of cannabis, it is advised that you contact your state’s governing agency to acquire the applications needed to become a fully licensed grow operation.

Once you’ve handled the legal side of things, the next step is planning out what you want your marijuana grow op to look like. Creating a list of materials needed for growing cannabis indoors helps keep you on schedule and aligned with your budget.

Grow Operation Set up

All plants require water to survive. Supplying your plants with pure water helps them grow and increases yield.

If you plan on growing cannabis indoors, you can rely on a modest greenhouse tent or an entire warehouse facility. The real planning needs to involve factors like grow room ventilation, lighting and hydroponic systems. Selecting the correct grow op supplies can have a huge impact on your overall output.

First and foremost, determine how many plants you want to manage in your growing op. This will help you determine how much space you will need. If you are planning a significant grow operation, say about 200 plants or more, it is crucial that you find the ample space to house them.Be sure to learn that the space you are choosing can be retrofitted with the necessary grow op supplies that will help keep your plants healthy.

Once you have decided where you want to launch your grow op, you’ll need to draft a monthly utility plan that helps keep you on budget. Understanding how much you’re spending on utilities will come in handy and can help you adjust selling prices accordingly down the line. Whether it’s heat, light or water, you need to implement systems that make the most use of your growing op space.

How to Grow Cannabis Using Organic Soils and Nutrients

Once you’ve located the right area for your commercial grow op, it is now time to consider what grow medium you want to use. Dirt and manure have been a steadfast go-to for years, but with new grow op supplies on the market today, it is important to know the choices available to you. One popular brand among growers is organic soil. Containing live microfauna and microorganisms, organic soil has the extra power needed to break down nutrients. This eliminates the need for harmful growth additives and makes absorbing nutrients easier for the plant.

When growing marijuana indoors it is also worthwhile to consider growing plants in hydroponic soils. These are usually constructed from a blend of peat, coco or sphagnum and help retain water and reduce costs. However, before you pick what soil to use in your growing op, it is important to factor in what type of commercial grow op water treatment system you will use.

Marijuana Grow Op Commercial Water Systems

All plants require water to survive. Supplying your plants with pure water helps them grow and increases yield. For this reason, you shouldn’t be stingy when it comes to choosing a water treatment system. Consider industrial water treatment services to get an understanding of what is in your water.

From there, give some thought to purchasing a commercial hydroponic system. Many of these systems are capable of ultrafiltration, deionization and reverse osmosis. Installing a hydroponic system in your marijuana grow op means your plants will be provided with clean, filtered water. It also means you can manage watering times.

Something as simple as choosing the proper commercial hydroponic system can have profound effects on the day-to-day of your grow op. Providing plants with high quality water pays off in the form of larger harvests and healthier plants. Installing a commercial hydroponic water treatment system is an absolute must when it comes to growing marijuana indoors.

Growing Op Lights

Equally important to your grow operation set up is the lighting system you use. Depending on the space you’re working with, you can either choose to have lights installed or install them yourself. Lighting systems can be fitted into the ceiling of your commercial grow operation. If you’re working with limited space, you could also choose to hang lights above the plants. Just be aware of the space between your plants and the lights. You want to leave ample room as to avoided burning and singeing the plants.

When it comes to picking a lighting system for your marijuana grow op, energy consumption should be your main concern. Again, because you are launching a commercial grow op, you want to maximize the output of your grow op supplies.

Chances are you will be running your lights for the majority of the day, if not all of it. Having an energy efficient lighting system will help curb costs and reduce your eco-footprint down the line. The second factor that must be considered when choosing a lighting system for your grow op is the quality of the light itself. Sure, you may be able to successfully grow plants using a standard LED light, but there are many more options available to you.

If you’re planning on using cannabis seeds, growing clones, seedlings or young plants, then fluorescent lighting is the way to go. On the contrary, when plants enter the flowering stage, they will need a wider range of types of light. Generally, picking an LED lighting system that also produces infrared and ultraviolet waves has been proven to promote plant growth.

Grow Room Ventilation

One of the last major factors that need to be considered before a marijuana grow op is ventilation. Airflow is generally measured in cubic feet per minute. Understanding the volume your grow op occupies is pivotal when picking the right grow room ventilation.

Taking the time to investigate the right air filters for your grow op setup is also a must. Carbon filters have been proven effective when it comes to removing heavy and impure particles from the air.

Dehumidification, cooling and air flow can tremendously impact a plant’s growing cycle, also. Too much humidity can lead to mold, while too much cool are can stunt growth. For these reasons, it is advised that you include a network of fans in your growing op. Having an intake fan, exhaust fan or network of oscillating fans can help supply your plants with fresh air.

Depending on the size of your commercial grow op, you may want to consider utilizing a ductless mini-split air conditioner. Their compactness is great for a smaller growing op, because the system can heat or cool individual rooms in an energy efficient manner. Other grow ups rely on entire HVAC systems to provide grow room ventilation. While there is nothing particularly wrong with this method, it is not the most practical when it comes to energy.

If you are already making the necessary plans to launch a grow op, it is worth considering a commercial water treatment system that can double as a dehumidifier. Chilled water treatment systems help keep temperature and humidity levels stable while save up to 40 percent more energy than a traditional HVAC system.

How to Grow Cannabis: Recreational & Medical Marijuana Michigan Laws

In 2018, the state of Michigan voted in favor of legalizing marijuana for recreational use. Over the years, it has become increasingly easier for a medical marijuana patient to receive prescriptions. While the state already allows the creation of a marijuana business for medical use, growing weed recreationally is a different story. With medical marijuana becoming more popular among patients and Michigan recreational marijuana use increasing, now is the time for you to take your slice of the pie!

While it is possible to launch an outdoor grow operation, it may not be worth the headaches that come with managing it. Aside from legislative parameters outlined in Michigan marijuana laws, other factors can delay or prevent cultivation. Along with legislation, the Michigan Marijuana Regulatory Agency also needs to be considered.

The Marijuana Regulatory Agency establishes Michigan as the national model for medical and recreational marijuana production. The agency seeks to stimulate business growth through safe cultivation practices. In order to start your marijuana grow op, it is pivotal that you check with this agency, as well as the state.

Creating a Profitable Growing Op

The cannabis industry is undergoing a boom. Demand for recreational and medical cannabis is skyrocketing. Making the decision to start your own grow op is one that must be made with careful discretion.

It is important to remember that the success of your marijuana grow operation hinges on the grow op supplies you use. Whether you’re launching a residential or commercial grow op, you need to have ample space and resources.

Of those, water is among the most important. There is an extensive list of water treatment services and products that can positively impact your growing op. No matter if it’s ultrafiltration systems, reverse osmosis systems, deionization systems or commercial water filters consult a reputable water treatment company.

Materials needed to grow cannabis indoors

If you’re thinking about setting up your very own indoor cannabis set up but you don’t have much experience, you probably have a lot of questions. What are the materials needed to grow cannabis indoors? How much will it cost? These are two of the most frequently asked questions regarding growing cannabis indoors.

We’ve decided to write a full post on the exact materials needed to grow cannabis efficiently and affordably for all of the beginners out there that are a bit overwhelmed.

Materials needed to grow cannabis indoors | The first step

Before buying anything, the first thing you’ll need to do is figure out where you’re going to set it up. Are you using a full room, a wardrobe in your house, or a grow tent designed for cannabis growing? Depending on your chosen method, you’ll have to spend more or less money.

You need to calculate the amount of space you’ll need while also keeping in mind the fact that you’ll need to be able to move about and get to your plants and devices. You’ll also need to think about where you want to place the intake and outtake lines for your extraction fan.

Once you know where you’re going to grow and how you’re going to distribute the space, you’re going to need to make a shopping list.

Materials needed to grow cannabis indoors | The Shopping List

Shopping lists are highly recommended so that you don’t end up spending more than you need to spend on unnecessary or expensive things. If you take your time to have a look at the current market and options, you can save quite a lot.

Materials needed to grow cannabis indoors:

  • Grow tent or reflective sheeting if growing in a room or wardrobe.
  • Lighting kit designed for growing cannabis.
  • An extraction fan to remove stale air.
  • An odor filter in accordance with the strength of your extraction system.
  • A fan for moving air around the room/tent.
  • Pulleys for raising and lowering your lights.
  • A timer for turning the lights on and off.
  • Thermos-hygrometer to control the humidity and heat.
  • 10m of pipe for your inline and extraction fan system.

There’s a longer list with more things that we didn’t mention, as they are usually things that everyone has at home anyway, such as duct tape, clamps, screwdrivers and other bits and bobs.

Materials needed to grow cannabis indoors | Step by Step

We’re going to have a quick look through the items we mentioned earlier on our shopping list so that you can figure out for your own which models work best for you and which ones you don’t need.

1- Grow tents / Reflective sheeting

In order to grow cannabis indoors, your plants need absolutely no light during their “night time” which is why it’s incredibly important to use a grow tent or set up a wardrobe so that no light can get it, or even better, a whole room – but this can be a daunting task.

If you’re planning on using a grow tent, there’s no need to worry as they’re fully sealed so that no light can get in. If you’re growing in a wardrobe or in a room, you will need to cover every inch of the walls in reflective sheeting for grow rooms, making sure that absolutely no light can get in.

  • For wardrobes: you will have to cover all of the walls (not the floor or ceiling) of your wardrobe. You’ll also need to make two holes – one for each side of the extraction. It can be a good idea to compare different grow tents by size when choosing the right one.
  • For rooms: it honestly may be too expensive to fully cover a room with reflective sheeting. We recommend starting at the bottom until the height you expect your plants to grow to, which is usually around 1.2-1.5m. You’ll have to make absolutely sure that no light is getting in from the door or the window.

2- Grow lamp / Lighting kit

When growing cannabis indoors, you absolutely have to use some sort of lighting system potent enough for your plants to believe that they’re outdoors, allowing them to grow and flower perfectly.

Your choice in lighting kit also depends on the amount of money you’re willing to spend, the space you have available and the amount of cannabis that you want to grow, as well as how strong you’d like it to be. Keep in mind that you’ll also be spending more on your electricity bills; a 250w HPS light uses much less than a 600w HPS light.

Once you’ve decided where you’re growing and you know how much space you have, you’ll need to buy a grow lamp that is in accordance with what you need. We’re going to have a look at the different types of bulbs that are generally used when growing cannabis and how much space each of them can cover.

Type of lamp, strength, average yield and space covered:

HPS lighting:

  • 250w: 150g, covers 80x80cm at 25-30cm from your plants
  • 400w: 300g, covers 100x100cm at 40-50cm from your plants
  • 600w: 450g, covers 120x120cm at 60-70cm from your plants

LED lighting:

  • 100w: 80g, covers 80x80cm at 40-50cm from your plants
  • 200w: 150g, covers 100x100cm at 40-50cm from your plants
  • 400w: 350g, covers 120x120cm at 40-50cm from your plants

LEC lighting:

  • 150w: 150g, covers 80x80cm at 20-30cm from your plants
  • 315w: 315g, covers 100x100cm at 30-40cm from your plants
  • 630w: 630g, covers 150x150cm at 40-50cm from your plants

The yields mentioned above are the average numbers obtained under normal growing conditions. Professional growers can definitely harvest more than that, and beginners will most likely harvest less. When it comes to the lamp distance, this can also depend in the growing conditions and your plants’ health. These numbers are simply a guide.

3- Indoor extraction system

Extraction fans are essential when growing cannabis indoors for two reasons. The first reason is that your plants need fresh air; they can’t sit in the same air for too long. All plants need certain levels of CO2 and Oxygen, which they use for different processes depending on the time of day (if it’s daylight or nighttime). The second reason is that if you don’t have an extraction fan, heat will build up in your grow room which is disastrous.

When buying an extraction system you’ll need to take down how large your grow room is (in cubic meters) and how strong your grow lamps are. There are other factors that influence the type of extractor you’ll need, and it can be quite hard to find the absolute perfect extraction system. Things like the temperature in your grow room, the temperature outside, the type of lighting and many others can also influence the extractor fan. We’re going to show you a quick solution to figuring out the type of extraction that you need.

Growing area:

If you’re going to be growing cannabis in a 1.2×1.2x2m grow tent, you’ll need to use this equation:

1.2×1.2×2 = 2.88 x 60 = 172.8m 3 . This is the strength that your extraction fan will have to reach to be as effective as possible.

Lamp strength:

This calculation is done by taking into account the temperature outside your grow room and your lamp strength. In this example, the temperature is 20° and the lighting system is 600w:

600/1.28 = 468 m3/h is the extraction speed that you need due heat difference indoors and outdoors.

This calculation allows you to keep the temperature in your grow room at a 4C° difference compared to the outdoor temperature. If you’re taking in 20C° air, your grow room will stay at 24C°.

4- Inline fans

Inline fans are just as important as extraction fans, although if your extractor is strong enough it can create negative pressure which can cause air to come into your grow room without any sort of extra inline fans. This only works with Grow Tents, as they tend to come with passive breathing holes, although if you’re using a room or grow tent you’ll need to sort out air in-take yourself.

In order to calculate the inline fan strength you’ll need to calculate a fourth of your extraction strength. So, if you have a 1.2×1.2x2m grow tent and a 600w lamp, you’ll need a 468m3/h extractor. So, for your inline fan you’ll need to calculate 468/4 which is 117m3/h – this is the type of intake that you’ll need.

5- Carbon filter for indoor growing / scrubber

When you grow cannabis indoors the biggest giveaway is usually the intense aroma that cannabis plants let off during their flowering period. If you don’t want anyone calling the cops on you, we highly recommend installing an odor filter of some sort.

In order to know what type of filter you’ll need, you’ll first need to know what inline fan and air filtration system you need. We did this earlier, so let’s skip to it; we know that the 1.2×1.2x2m grow tents need a 468 m3/h fan. Now, all you have to do is find an odor filter with the same sized opening and slightly stronger.

This means that the perfect odor filter for this set up would have a 125mm opening and should be almost 500m3/h. This avoids any mishaps with the filtration system, which can happen if the filter strength is less than the actual extraction itself, causing air buildup. If this were to happen it may be fatal for your plants, especially if you don’t realize that it’s happened.

The extraction fan may break due to overexertion and your plants may get sick due to breathing old, stale air – you may even have some problems yourself, as the smell will begin to build up and depending on the legality of your situation, the police may get involved. Remember that your odor filter should always be slightly stronger than your extraction fan when it comes to m 3 /h.

6- Ducting

If you have an extraction system then you’ll also need an inline fan systems need ducting which needs to be durable, flexible and fully opaque, and obviously the same width as your inline fans and other devices such as filters.

For your inline system to pull as strong as possible, your ducting will need to be as straight as possible. Every bend in your ducting system means that you’ll lose a bit of strength, around 50%, which can reduce your carbon filter and end up stinking up your building as well as being quite bad for your plants, providing them with less fresh air than they need to successfully grow.

7- Fans

Having a fan in your grow room is an absolute must when it comes to the materials needed to grow cannabis indoors. Two of the biggest factors that fans affect are plant breathing and the heat in the room or tent.


Proper ventilation is incredibly important for plants to breathe, and an oscillating fan does wonders for rustling your plants’ leaves which induces breathing. If you grow plants with absolutely no fan or any sort of air movement in the room, your plants will grow super weak, as a slight breeze helps them to get stronger and hold up more flowers. Plants grown indoors without a fan are also more susceptible to insect and fungi infestations.


Fans can also help to remove some of the extra heat in your grow room generated by your lighting system. Excess heat near the tips of your plants can cause them to grow thin and wiry and their flowers may end up opening up and losing quite a lot of terpenes.

8- Pulleys

Pulleys aren’t really that incredibly important but they are super practical. Pulleys allow you to raise and lower your lighting kit and reflector whenever you want. Many people set up a rope system to save a bit of money, but honestly pulleys aren’t that expensive when it comes to how much easier they make it to get stuff done around your grow tent or room.

9- Timer

Having a timer in your grow room means that you don’t have to manually turn the lights on and off every day in order to keep your plants in the growth or flowering periods. It’s pretty impossible to do for so long, anyway. Timers aren’t that complicated, just make sure to get a decent one; if you decide to cheap out and get a bad or faulty timer, it may not work correctly and end up completely ruining your plants.

10- Thermos-hygrometer

Thermos-hygrometers are designed to give real-time readings of the relative humidity in your grow tent or room, as well as the temperature. These devices are vital when it comes to giving your plants the right parameters to grow in – cannabis plants need a specific temperature and relative humidity during each period in order to develop properly.

Most thermos-hygrometers also keep a record of the highest and lowest of both readings, so you’ll know if something is wrong when it comes to your plants’ night cycle. This makes it much easier to know exactly what it is that your plants need in as far as their environment.

Materials needed to grow cannabis indoors | Conclusion

As you can see, the materials needed to grow cannabis indoors are varied but not that complicated. You essentially just need 10 things to successfully grow cannabis indoors. The only things we left out of this post are the seeds, substrate and nutrients. Well, what are you waiting for? Get to it, make your shopping list and take your measurements.
