yeh my temps dont fluxuate at all. When the lights are on, its like 85 degrees with one fan blowin, n im bout to go pick up another one to cool things off even more, plus a small one for exhaust when i hook up my DIY carbon filter (thanks zen). and in the dark its like 70 degrees, so its pretty steady no matter what - i dont open n close my closet all the time. When the lights are off, i make sure that i aint goin in there all night long. When lights are on, i leave the closet open to get some ventilation goin through there so they have as much fresh air as possible until i get the exhaust goin on.
Also an update - im gettin a lil bit of nutrient burn goin on again - i think im gonna chill on the nutes n just feed the ladies every 7-10, and give them distilled every 2-3. I think im startin to get a feel for how my plants react to certain shit i do to them. feels pretty good, almost like im startin to know what im doin, lol.
