I have a 3ft wide by about a foot and a half deep stealthbox for growing. I am determining what kind of pots I can use. Originally I was going to use 2 five gallon buckets but now I am thinking of using the square pots to maximize the smaller grow space. So should I use 2 buckets or 3 of these Black Urban Garden Container w/ 25 Trellis : Sunshine Hydroponics, Tools to exercise your green thumb! or 4 of these 7 in x 7 in White Square Pot [SKU7726] : Sunshine Hydroponics, Tools to exercise your green thumb! The box is only 3 feet tall and all plants will be LST'd.
