I've considering switching to 5 gallon grow bags. I currently use 3 gallon grow bags.
I think it can be if you don’t have enough wattz then it’s a waste. Small closet grow may not need it. How big is your light?
Post your light info and one of the LED gurus can help. Your plant will only get as big as your light allows. If you don’t have enough light I don’t think you will benefit from larger pot size600w led but its actual power draw is probs lower
