How to determine the sex of a young plant

What is the preflower (calyx) of cannabis? These are small versions of "adult" flowers that appear on plants while still in the vegetative stage. They can be identified as plants.

Typically, male cannabis plants are ready to flower at 3-4 weeks of age, females at 4-6 weeks of age.

Constant inspection of the plants is necessary to identify and remove male plants from the grow room as early as possible.

Only the female plants produce powerful buds, while the male plants produce pollen sacs.

In addition, it is very important to protect the female plants from any contact with the pollen of male plants in order to obtain a product of the highest quality, the so-called sinsemilla - a plant without seeds.

If you start your grow with feminized seeds , all plants will eventually be female. In this situation, determining the sex of the plant is not necessary.

But for regular seed growers , about half of the plants may be male. Unfortunately, we are not yet able to determine the sex of plants by simply looking at the seeds.
