when is it cool to work on your room?

ok so i just put my baby's to sleep for the first time after transplanting them into my system. i am giving them 12 on 12 off for the first few days before i kick it up to 18 - 6 but i think i might be having some temperature issues ... maby i should use the air cooler's on the hoods yes? lol

O and is it only cool to work on that kinda stuff durring the light stages?

no need for 12\12 b4 18\6 just go right to 18\6. if anything give em the 6 dark first to recover from transplant
i work in my room when the lights are on usually water in the begining of light cycle i wish i had an air cooled hood why wouldnt you use it if temp is a problem, make sure exhaust and intake are proper, dnt mater mutch when you work on it during veg, but during flower no light at all dnt open the door just wait for the light to come on

circulation, exhaust and intake

six in the dark first ... got it ... sounds better then what i did ... i will do that next time thanks for the tip ... lol
