Hi grasscity, so i broke down and starting a journal that i promised my self i wouldn't! Not my first rodeo but my first in a stealth cab Exhast 3 120mm coolmaster fans Lighting 200 watt Feliz Cfl mougel e89 Reflective hood with adapter Intake 4 2inch intake holes 2 1inch intake holes Raised False floor with no holes and 2-3 inches gap for air 2 120mm cpi fans for circulation 4inch fan for circulation Room always at 70 degrees Lady Stuff Smart pot 2 gallon Foxfarms oceanic mix x2Barneys Farm Critical kush 1 TH Seeds Darkstar 1 Cali connection Original Sour Diesel THE BREAK DOWN When i built the box i miss caulated so the door is 1 inch short wich leaves a gap when closed. (is getting replaced by the end of the week) So guys average temp with door open is is 75 degrees but when i close door temps reach to 90 Im going with neg air pressure to cool off the cube, but not fully complying to the theory because im not air tight.(yet) Can not having the room air tight raise my temps that high ??? My other thought was the false floor does not have holes in it, so my second though is that the air circulation sucks because its only coming up the sides. So my 2nd thought is to make holes oppisite of the intake to promote better more consistent airflow.. Ive been part of the community for 5+ years but tis the first time ive posted due to needing help! BLah i need help and i know by experience 2 stoners are better than one THX GC !
