So....as a couple of you may know ive been struggling with lights off and lights on temps, both being around 2 degrees c to high (24c lights off & 30.0c lights on), Now I've come across an issue...yeah another one.....becusee of the heat of the room with the sun hitting it for a few hours a day, it raises the room temps which in exchange raises my grow tent temps with a knock on effect making my extractor run harder, Now when it fully kicks in to keep the temps in range which it's struggling to do for some reason as it was the best fan in the shop (6inch rhino Thermostatic adjustable extractor), but I've noticed it sucks my tent right in on all 4 sides, ive measured it and worked out im losing more than half a meter from my grow space and my grow space is only 1.2meters x 1.2 x 2.0meters.....so I'm growing in less than half my grow space when temps raise to high, Would this affect the airflow coming in? Rather than it coming in filling the tent with coolish air and then exiting thru the exhaust......is the extractor just tugging away directly at the fresh air? With it being so small i couldn't see if filling the tent correctly? I am considering side support bars to stop it sucking in but the point to this thread is......could this problem be contributing to my heat problems with the growing space going from.1.2 meters squared to say half that? So 600mm of growing space? My head is all over with this I cannot put my finger in enough pies to figure this out as a newbie grower!!! Driving me crazy!!!
