thankyou both soooo much, you guys really know your shit so il take it all into consideration. The temps are under control, iv set up a prop/cloning area with some t5's. My only problem is pH balancing and im really stuck and pH isnt staying the same in my autopots. The pH in the 30L resevoir is fine and hasnt been changing but the water in the autopot resevoir is changing so often. Im sorta stuck here. If you want to know what im growing in just google "auto-pot" and i have a hydropack 2 pot system using strait perlite.

Thanks again guys
