Co2......30 Min On...30 Min Off

[thatoneartist]

sound right? I find it hard keeping it around 1500 ppm's turning it on and off so I have just been keeping the co2 flowing all thru the lights on period.

 

the tank gets kinda cold....is that okay?

yup, cold is fine.

There are a couple of variables to go by. You want to go by the size of the room and wattage you run. But in my opinion 30 on and 30 off during the light cycle maybe a little much. You have it on a timer so what I would try is to have the c02 on for 10 and off for 50 with your exhaust fan coming on before each co2 cycle. Adjust your regulator to let out the same co2 during the 10 min as you would during a half hour. I've run mine like this and seems to work great but that is just one theory. I bet the cold tank will help out when the temp rises in your room though. Have fun experimenting

Using Co2 with only a timer = No control. IMHO You really need to consider buying a Sentinel controller with Fuzzy Logic.

$600.00 looks great and works great
