just to put my 2 cents in i want to include a different floro...
its the floros i use to grow.. well for my first 5 grows i used them.. i added a couple hps in with them (hps lamps are cheaper than these) for this grow...
they are sunleaves satellite IV floros.. 420w - 4 bulb ballasts that use tt-105 bulbs.. 44,000 lumens per ballast... 11,000 lumens per bulb.. hottest running temp is 95F... i am able to keep them with an inch or two of any plant without them burning at all.. including new sprouts...
they easily would blow a 400w hps out of the water.. and im fairly confident in saying that they would at least keep up with a 600w hps... if you dont believe me check the youtube video in my sig with my last grow.. they were about 5 weeks at the time of the video...
now i also think if they could make a 1000w ballast such as this it would easily beat out a 1000w hps bulb.. but i cant prove that and nor do i want to start that debate...
here is a link to them if you want to see them..

anyways ill post a couple pics of the plants i have going now and my grow room.. believe me when i say the floros work MUCH better than the HPS lamps i have.. but again, the hps was purchased because i didnt have a grand to buy 2 more of the floros.. i am also going to get 4 x 1000w floros for a flower room i am setting up.. but again, if i could afford to get the equivalent in the floros i would do that.. but 4000ws of these floros would cost me 4000 alone.. which is WAY more than the HPS.. if they ever come out with a 1000w version of my floros tho i will sell that hps and switch over...
the pics are random ones from last week.. i update pics in my journal on thursday if anyone wants to see how things are progressing...
