Brotha it depends on SO MUCH. What area will you be growing in? Whats your budget? Your cheapest most basic way of growing would be to use CFL's. In that case drop 50 bucks on CFL's and you could grow in a card board box or cabinet if you wanted to. Also if you want a smaller size plant you could veg for 2 weeks with CFL's and then switch to flower and from that point your looking at anywhere from 7-13 weeks depending on strain. Indica's have shorter flowering periods and Sativa's longer. So bare mininum it would take you about 9 weeks from start to finish. But like I said there so many factors. Nutrients, air flow, lighting, space, and much more. You cant just throw a light over a plant and think youll strike gold. IT WILL NOT HAPPEN
