I do not know much about US legalities but, you can probbly do fairly well with a closet grow, from clone to bud your looking at about 3 months, we have some reliable seed companies that this site works with pm if your interested and I will help you out. If you can find clones from anyone that is the easiest starting from seed is more of a pain, but once you get your females and toss your males your on your way. Depending on how much you would need to smoke per day, just figure out how much you need to grow.
Sorr if this doesnt make sense I just woke up
