Male plants should be sorted out as they would otherwise pollinate the female plants and thus produce seeds, which would affect yield quality and quantity.
How do you recognize male plants?
Male plants become larger than females and therefore have a thicker stem.
Male plants have less leaves.
You can clearly recognize male plants already about 6 weeks after the germination.
At the latest the sex can be recognized about 1-3 weeks after the plants are brought into the flowering stage.
Male plants can be spotted by the small sacks which grow out of the stem together with the leaves. On male plants these sacks are rather small, round and have no hairs. Sometimes there may also be sacks which have hairs on a plant, these are like male plants.
If you grow male plants in an separate room to produce seeds, you must be careful not to carry any pollen from this room into the actual grow area.
