Enclosed by these bracts and imperceptible to the naked eye, the calyx refers to a translucent layer over the ovule at a flower’s base.
A node is a point at which a branch grows off of the main stem, or one branch from another branch. Fan leaves and buds can grow on some nodes, but not necessarily all.
While both result in pollen production, true hermaphrodite cannabis plants produce sacs that need to rupture; anthers are exposed, pollen-producing stamen.
Also known as “buds,” the flowers of a cannabis plant are the fruits of your labor. They contain the cannabinoids and terpenes that get you high or offer health benefits. Flowers only grow on female cannabis plants and must be dried before consumption.
Branches grow out of the main stem and support fan leaves and buds. Growers often train a cannabis plant by topping branches to create more bud sites.
Otherwise, all remaining plants will reveal their gender in the first 1-3 weeks after lights are switched to 12-12, and plants enter the flowering stage of life.
In fact, with marijuana plants, the length of night period, not the length of day period, seems to make the biggest difference. This makes sense if you consider that in the wild, a stormy or cloudy day could shorten the light period a plant receives, but few things in the wild will interrupt the darkness of night.

Female marijuana plants start showing one or two wispy white hairs where their buds are going to start forming.
“Auto-flowering” marijuana strains pretty much ignore how much light they get each day. Generally you don’t run into these unless you buy them particularly from a cannabis seed bank.
