Cannabis prohibition continues to fall state by state, giving more consumers the opportunity to grow their own marijuana. However, many of those states also have inconsistent or confusing laws regarding home cultivation.
For instance, browsing this list you may notice limits on mature plants, like those ready for harvest, versus immature plants, like seedlings just beginning. In cases like these, people are allowed to maintain a certain number of plants, but only some of which may be flowering, or about to flower, at a given time. Laws like these encourage the grower to keep a rotating cycle of small and large plants.
