hi i have a reasonable size grow going with a few lights on so i would like a way to hide any heat signitures from eyes in the sky i noticed a few mentions of ir blocking sheets any1 know were i can get this from?
is it worth using extra Co2 when growing alot? are the results that noticable?
if your gunna do it do it big!!!
Try using mylar insulation
from what i've seen on CO2 on other threads its bestt o rent ur tank and get it refilled. it definitely makes a big difference in the plants metabolic rate
