You need to check every plant to determine if it is male or female, as one rogue male can wreck your harvest. In general, male plants show their sex 7-10 days (indoor) or 3 weeks (outdoor) before female plants.

If you’re trying to create new plants or reproduce, you need to leave these balls undisturbed. Female plants will have these bulbs too, but will also have long, translucent hairs on them. If you only see 1-2 on a plant, wait and see if more develop before cutting them.

“Hermies” are generally undesirable plants, and they can ruin a small crop with their pollen if you’re not careful.

You can purchase “feminized” seeds as well, which usually create close to 100% female plants. However, there are occasional errors, and you should still keep a close eye on your plants to make sure there are no rogue males.

Male plants will have the small buds (pollen sacs) but will not have the associated hair growing out of it. Plants can grow both pollen sacs and pistils. If it does, it is hermaphroditic and should be treated like a male.
