Once your marijuana plant grows its first set of regular leaves (i.e. not the seedling leaves), it has officially entered the vegetative stage.
Thus, if you want your plants to reach a height of 3 feet, you would need a 6 gallon pot. If you are using fabric pots (as I recommend) go twice as big. In this example, get a 12 gallon pot (or at least 10).

Conservatory, Solariums and Sunrooms for Growing Weed
This is a reality of growing cannabis. Both light and darkness at critical stages of its life cycle are necessary for it to thrive. While plants can grow with continuous light during the vegetative stage, a significant period of darkness will cause it to create buds and reach sexual maturity during the flowering stage.
Greenhouses for Growing Weed
