I agree with all replys.
3 gallon/or 10-12 inch pots; is plenty large enough. Take the pots now and lay them in the total floor light space...(10x10 ft.?)...this will show you your max female flowering plants, total...:thumbsup:

I use a cordless drill to drill extra holes. Good drainage is critical. I am currently experimenting with 4 gallon, tall, square, waste paper baskets...:jointsmile:...tall pots seem better than short round ones?...we'll see....they use a lot of soil...not sure it's worth it?

Good Luck!
