I already have the res on the floor. Someone suggested I use frozen 2 liter jugs in the res to bring down the temp. CO2 at 1500ppms promotes photosynthisis in all stages of growth and allows you to maintain higher air temps.
mfisher1301 Reviewed by mfisher1301 on . Water temp? I am running an Aeroflo with a 40 gal res. My air temp is at 83deg my co2 is at 1450ppm humidity is at 60% I am in my 2nd week of veg. My exhaust is on a thermostat set to purge at 85deg. I am using a small chiller and my water temp is at 76deg. Is my water too warm and how can I bring it down? If I lower my room temp the water temp also goes down in proportion. My only problem with that is if I lower the exhaust temp I lose too much co2. Any suggestions? Rating: 5
