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?
I tried not to go over 82 degress. I keep my temp between 72 to 78 deg. I'm not familar with co2 application but you can have exhaust connected to your light. which mean you connect a flex tube from an outside air to the light & then on the other end connect a flex tube to your exhaust(if you have an enclosed light fixture). it reduce the heat of the light quite a bit. & with fans in the room you should be fine.
My co2 is dispersed into the air from a tank via a controller and regulator. When I exhaust my heat I also exhaust my co2 (waste of gas).I try to keep that down to a minimum. I am using ledā??s for lighting so I donā??t have much heat being generated there. My room is a sealed environment. Most of my heat comes from my dehumidifier, water pump and fans. I know my air temp is ok, I am more concerned with my water temp. is 76deg going to cause me problems with my roots, nutrient solution and overall plant health?
Hopefully somebody with more experince in sealed area growing can give better advise. I heard to cooling the rez is to get 2 liter bottles, fill up with water & freez them & submerg into rez.
Thanks for the advice. I will try that. What I was looking for was to find out what the optimal water temp would be if my air temp is around 83deg.
Water temp should always be 68 degrees for max oxy content or as close as you can.
As far as the sealed room and co2. I hope it is not in an area with people or animals just in case of an accidental leak.
The temp in the room needs to be in the low 90's to use the co2 propperly. Your room should be flooded with co2 to 1500 ppm's for 4 hours and then exhaust completely and refill. This only needs be done during the 12 light hours. Exhaust to fresh air for the dark as co2 is not use in the dark.
If your room temps are not high enough you will not see much difference.
If you want to just bring up the co2 levels about 300 ppm's are normal, so bring it up to 500 ppm's and save money. In some places it is hard to run exhaust and fresh air vents so added co2 can help with a fresh air problem.
You can always upgrade your chiller to a larger model for better cooling capacity.
