Possibly final setup.

Bigger roots = bigger buds. I agree that you should think about 5 gallon buckets.

Grow bags are just what they say. Bags to grow in instead of solid sided pots. I had a grow in a shower stall once and I would take the bags that the potting soil came in and cut the top off and plant the seed in it. I put holes in the bottom for run off ( it was in a shower stall ). Worked good.

I use these fans and they move a LOT of air and are pretty quiet. You would need the bigger model but I like mine a lot.
