i assume yr in the states? It doesnt often get that hot here in the uk, but i use a cooltube for my 600w hps, and it keeps my room temps right down in comparison to the standard reflector i was using before, sorry i cant work in farenheit, but weve had outside temps of 30 degrees c here lately, and my room temps have got no higher than 28.5, not bad considering that my temps were 35+ degrees on similar days two years ago pre-cooltube, so maybe running yr hid's in air cooled reflectors would take the edge of yr temps if nothing else?? And u can get yr lights real close to the tops without burning em, i keep my 600 about 8inches away. As for the organic/hydro thing i cant and wont argue the fact that hydro is marginally faster and grows a bit bigger, but i only grow for the mrs and myself so speed and yield isnt that important to me, taste and just knowing theres no synthetic chemicals or minerals in my smoke is what i like about organics, doesnt bother me waiting an extra 2weeks or so for what i believe is far superior bud, plus i have two very hyperactive young kids and im self employed so i cant find the time for all that hydro maintenance anymore, iv always got 10 plants on the go, 5 in veg, 5 in bloom, sometimes i take clones if i get time, that brings me in around 15oz sometimes as much as 25oz every 2-3months, thats plenty for me an the other half.
