I have some plants that are in small 4" pots right now. I am going to flower 6 of them in a 10x10 room so figured I would put them in 5 gallon pots to do this. Will 5 gallon be a large enough pot for each plant or will I need bigger, and should I go from the 4" directly into the 5 gallon or should I go into a 1 gallon container first? Thanks in advance.
