This is the time when many novice growers experience the following doubt: When to cut the cannabis plants? Just observe and pay attention to a few important details that identify the correct time to harvest the marijuana

Depending on the variety of cannabis we have planted, the flowering time will vary significantly. Indica varieties will be ready to cut seven to eight weeks after the start of flowering, whilst sativa dominant varieties will require much longer. This time is just a rough guide, The seed bank should give the approximate date of harvest so we can estímate the date to cut our marijuana plant, but the exact date only the ripening of the trichomes can tell us.

The first clue that the plant gives us, that the time has come to cut it will be the amount of trichomes in the buds that have changed colour, usually to an orange-brown or amber color. The optimum time to harvest marijuana is when between 40% and 70% have changed colour, not before. It is at this time when THC levels are at their highest. With the help of a microscope we can study the colour of the trichomes. If they look a whitish colour it is a sign that they are not yet mature.

Once we have decided to harvest our marijuana, we must pay attention to the correct method of harvesting. Ambient humidity should be kept as low as possible, to avoid the inside of the buds getting damp. The plant can then be cut as a whole, or branch by branch

When all the branches of the plant have been cut, they should be tied with pieces of twine or string. Use scissors to carefully remove the large leaves and some of the smaller leaves (leaving the leaves that surround the buds and have a high resin content to increase production) so that the circulation of air through the buds is not obstructed.

So how to dry marijuana?

It is advisable to avoid climates that are too cold or humid, as drying will be slow and may cause mould. Neither should conditions be too hot or too dry for drying our marijuana bud. The ideal environment is somewhere dark and ventilated with a temperature of between 18 and 24ºC, and a relative humidity of 45-55%
