Oh yeah, I checked out that MH bulb..I have used the 1000w version of that bulb with good results, the better bulb in my opinion is there "warm" bulb, it has an enhanced spectrum, and blooms very well..If I recall it right, I get 19oz off four plants with that bulb. The big problem with that conversion bulb is that I will drop 35000 lumens!~ No way am I going to do that...I use standard Eye HPS bulbs that put out 85000 lumens...

But when they come out with a 80000lumen MH, I may look into it~
As far as distance between my intake and exhaust, they are how do you say..Kidy Corner from each other across the room.
I was using the shitty growbright for a couple years. about 4 months ago i bought the sunmaster "nuetral" spectrum 400w conversion bulb for flowering because it has UVB. I DO REALLY LIKE tHE SPECS ON THE EYE HORTILUX'S SUPER HPS BULB, and would probly buy one if they were cheaper. The problem is that I can only fit one HID light in my growspace , otherwise I'd probly get 3 lights.2 HPS lights going on the sides with a MH in the middle. was wondering have you ever used this stuff before? it sounds so tempting.

I think UVB is great for plants. Ecspecially the strains that are indiginous to North America and other places that have high UVB naturally outdoors. Thay have evolved to use UVB very effectivley. Indoor UVB is much more complex than adding a simple lizard light to your grow, contrary to what tahoe and other idiots think.
How so?
