I would say no. I use 5 gallon buckets (hempys) and put into flower at about 24 inches. I just put a tray of white russians in flower this week useing 11 liter pots in coco, perlite and hydroton but they were all about 12 inches. I have done what you want to do before and the plants finished but they got rootbound and the leaves turned yellow prematurely. How much light are you useing? If you are useing intense light like a 1000 watt you will have problems because the plants will blow up. If you are useing soil and a $00 then you could pull it off.
