I hear that. I have all my ladies in 3 gln airpots. The bigger ones that is.
I rarely go past a 3gln on "any" plant I grow. I still like to run my 5 gln bucket every once in awhile though.. Now talking about a BUSH! Sink that bitch down into a 5 gln bucket and you will have to get a tent!!
20$ at wal-mart. Roll waredrobe. I made one up myself. Took the emergency blankets from sporting goods, lined the walls with it, placed a little fan on the side, ran all the lights and cords out the back. Beats a 400-1,000$ tent bill anyday in my book.
I'm fitting (right now) 11 strains/ 13 plants. Its just what I veg in, it also has a little 2 x 3 section ontop that I use for seedlings & clones..
