The pic don't do it any justice,,the pot the plant is in is actually 4 gallons and that plant is exactly 3 ft 10 as we speak,,I think the pot is large enough in size,,I have 8 plants going in flowering as we speak 6 White Widows and 2 Northern Lites all between 3 1/2 ft to almost 5 feet and all in those 4 gallion pots,,,they seem to do the trick,,reason for using them is because of the room I was using to grow them in was not that big in size,,but now they're in my new grow tent and I still have some room left for a few more,,we'll see next time,,maybe I'll grow them out of the bathtub ,,lol,,,
