Good info on lumens, much appreciated.

Since my room is roughly 4X2 I can get a 4bar T5 and then maybe a couple small bars for the sides to help supplement...I would get a 400watt instead but I just don't have the means to cool the room im growing in...I have used a 1k MH/HPS in the past but my current living conditions just wont allow me that luxory.

I Figure I could fit a 4 bar 4foot setup in my clsoet which would work well for heat issues, and they say they put out 5000 lumens per bulb, which I could scrog under and being so close to the plant it would be like using somewhere between 250 and 400watt HPS. Any thoughts? Rating: 5
