I use 3 and 5 for flowering indoors. Depends on the plants; some need more room from the 5 gallon, and others are fine with 3 gallons all the way through.Thanks man, do most people use 5 gals? 3 gals? I can't decide.
Master Kush/WW.. Flowering 3-4 weeks from seed, will harvest a few days earlier as thats how I like the high.
Again, thank-you for your help it is much appreciated!
