For Full Plant Maturation (Maximum Space Available)

Rule of Thumb: Add 1 Gal Pot for each feet you want a plant to grow up to and 5 - 7 Gallons bucket is enough for all size you could reach indoor.

In other words, If you want 3 feet tall plants then use 3 gal pots and if you want 7 feet tall plants use 7 gal pots.

Hope this helps

Happy Growing! :smokin:
