Temps over 90`f

Your problem is not the lighting its the set up. I ran a couple of tents with 600 watters and was able tokeep it below 80. You said it was in your bedroom...do you have a window? The point being you need to bring in cooler air to the tent. A single intake from the outside will eliminate the need to drop your lighting.

There is no lesser evil as you say, RH and temp go hand in hand, dropping to cfl's will increase your RH because you loose the dry heat from the hps.

Proper air flow is what you need not less light. A/C or cold outside air is what you need.

Good Luck

Bring in cold air from outside if it's cold, if not just try to cooltube way of venting your heat out or just buy a used a/c unit, because as of now your killing your THC anything over 90 is just BAD and your high will never be there if you allow it to keep going like this. I had mine up to 95 and you wouldn't want to see what it looked like after.

Not sure how Accurate this post is, but On my google searches it "SEEMS" to hold water.

(Im also Pretty sure that the breakdown rate is not the same When the plant is alive and still growing, apposed to when it has been picked)-Just a guess.
