Germination | 1-2 weeks for your seed to sprout into a young seedling.
Vegetative State | Growers can veg their plants from as little as a couple weeks, or keep them in a vegetative state indefinitely. (I.E. mother plants are kept in veg state. clones can then be taken from a mother plant every couple weeks. this perpetual grow cycle allows for quicker flowering phase with the guarantee of female plants). Plants are kept in veg state by providing typically 18+ hours of light per day....
Flower/Budding | Once a plant has reached a desired height, the grower can then switch Lights from 18hrs/day down to 12hrs ON / 12 hrs OFF per day. This will force any female plants to start producing buds.
* People can also start 12/12 from seed.
