The truth in my opinion that pot size is irrelevant with proper soil mix and constant nute and water in proper dosages. Long veg time with heavy training and topping in at least 3 gallons and you can blow norms out of the water. I only have outdoor now. 5 & (1) 10 gallon holes. Root balls won't be much wider than the holes and maybe 18" deep. I've grown several large plants in small pots and spaces.
