im growing in a tent about 2x2x5 i have 3 105w cfl in there at about 3 inches off the plant. the plant seems to be doing just fine but im having a hard time keeping the temperature down. near the plant its getting almost 90 degrees but in the tent itself near the top its only 80. i have a fan for intake(at the bottom) and exhaust(top) and one fan oscillating on the plant my question is are my temps too high? is 90 degrees risking stunting the plant or otherwise harm it? like i said the plant itself doesn't seem to mind being that close to the lights no signs of burning and there is still constant growth. is there anything i could do to better control the temperature inside the tent? oh i also made one of the diy co2 generators with yeast and i think i read that the plants like it a little hotter when they have more co2 to work with how much hotter?
