heat is a deceptive bitch. I just had to replace a 6000btu w/a 15000btu and it's fall. i added 1k to the room and the temp went up 8-10 degrees. i thought the 6k could do it, but i was wrong. my 4way hybreds are picky, picky, and started yellowing in 2 cycles of light. yep that fast. no central ac is making this fun and challenging, but hey, what else would i be doing? 9to5...lol
gl hn and heat will cause those spots too. heat + not much air movment?
I would wonder about the solubility of atmospheric N at different temps- our atmosphere contains LOTS of N2- I don't know off hand how it could become available in your res, but Delta9Haze might be around somewhere... ? :D
Interesting observation. Earlier in the summer I got the bright idea of buying a portable evaporative cooler to use to try to keep the temps in the closet down. It worked great for a couple of hours until the RH in the closet got high enough to stop the evaporation from happening, then it just became a fan - an expensive fan, I might add lol.Quote:

And guess where all the spotting is :rolleyes:
Oh...and turning the fan off completely dropped my closet temps about 8 degrees. Guess that fan motor puts of a lot of heat on its own.
Um...well...I *did* add an airstone to the reservoir a few days ago........:DQuote:

the ac keeps the room at 75 lights on 6O off. problem is the ac is too big to pull out the humidity. reason: it doesn't stay on enough. it works in short burst, so guess what is on tap for today? yep, work a dehumidifier into the room. 3OO sq ft w/2k hps. 1 of 4:)
