Ukstoner I have grown 2 plants in the Marshydro 27X27X63 inch which is a similar size. It is doable but cramped. The height is my main complaint because it forces my plant heights to be 24 inches max basically... Hope this helps and happy growing ✌️👊
I’d say so.. 80x80 you could fit 4 at a push, I currently have 6 in a 1.2x1.2, if you plan to grow more plants in the future your best bet would be to get the biggest tent you can for your space✌️
