The embryonic plant protected by an outer shell, formed when pollen fertilizes the female plant. Marijuana seeds are ready to plant and grow once they successfully germinate, or once the root has broken through the seed. They can be found in multiple forms; regular, feminized, and auto-flowering. Home growers of cannabis often choose to grow feminized seeds to ensure that the adult plant will be a flowering female.
Cannabis seed production begins with the pollen grain of a male plant. From this grain, a pollen tube grows, producing male generative cells that disperse in the form of pollen. The migration of pollen into a female plant ovule triggers pistils to fall off and seed production to begin. The bracts, which contain the ovule, will then fill with seeds.
What's the difference between feminized, regular, and autoflower Seeds?
Marijuana seeds can be feminized by two different methods : chemical ethylene inhibition, and rodelization. In the first method, a chemical agent (colloidal silver, gibberellic acid, etc.) is applied to the plant to inhibit its production of ethylene, a plant hormone that induces female flower production. Rodelization is a less-used technique that involves exploiting a natural self-defense mechanism of the plant. An unpollinated female cannabis plant with fully mature flowers may, in some cases, grow pollen sacs to fertilize itself to ensure its propagation. In both cases, pollen is collected and used to fertilize other female plants. Given the absence of Y chromosomes, seeds that result from the mature buds are female.
