I have something like eight 23w's, eight 26w's, one 42w, two 23w's, and four flourescent tubes.
Heat isnt horrible, but if the house has the windows open (and the a/c off) it will sometimes rise over 90. Usually its around 85 with lights on, 74 off.
My magnifying glass isnt powerfull enough. I cant see shit when looking at the trichome colors.
