right now im using a 32 gallon tub.

3 an half feet long and about 2 and a half deep!

i have two tubes that are called t 8 tube the fat tubes

and also 4 compact flurecents about 23 watts each all to gether well over 7,000 lumens but i dnt even no if im gonna get good buds or not but the plants i got are growing fast as hell with those fat tubes.

trust you want ur plant to get at least 2 feet to get some kinda chronick im shootin for 2 in a half.

i got my tub at k mart for 10 bucks and a ten dollar fan also and went to home depot for the t 8 they also have t9 and t 10 and 12 and etc.....

my bulbs were 5 dollars each but you also have to have a 2 tube ballast.
