6 of the two bulb fixtures.. 12 bulbs in total.. would bring you up to recommended lumen for that areaKing Bud said:Six 4-foot T5 fluorescents would fill that. Half of the bulbs blue, the other half red.
You'll need a carbon filter and a fan too.
I was able to get 8+ ounces in a grow out of an area 2ft by 4ft by 9 ft with t5s....... I had 12 4ft bulbs in the area........ heat and odor were my enemies....... I won't use T5's to flower again I love them for veg....... a 600wat HPS carries my grows to dankville and there will be no going back to less than dank.:icon_smile::icon_smile:jimreadynow said:I have a space roughly 3 ft by 4 ft by 7 ft. Is it possible, using only florescent fixtures and bulbs, to be successful growing marijuana. If so what bulbs and how many fixtures.

Yes, Harley has done it, but have you checked the watts he is using? As I remember, he is running over 2000W of CFLs. He could most likely be running a 1000W HPS and get a better yield. Half the watts, more bud, it is a no-brainer to me. I truly do not understand anyone wanting to use CFLs for flowering when HID are so much cheaper and better.powerplanter said:It's not popular around here, growing with flo's, but if you look up faderharley check out his grow that he did with compact florescent bulbs. Welcome to MP, stay safe. PEACE!! P.S. If smell is not a problem you can do without the filter.
