CO2 Started today-
I have a Green Air co2 regulator/dispensing unit that I just hooked up today. The unit will be nice for the room, but way over-kill for the tent.
I found this link http://www.hydroponics.net/learn/co2_calculator.asp to a co2 calculator that lets you know how long to leave the co2 on to get 1500ppm of co2 in the room. You give the room dimensions + co2 flow rate and they give the time. For my tent it said 1.008 minutes. So every hour, on the hour I flow 1 minute of co2 into the tent. The tube that provides the co2 to the tent is hooked up to the back of the fan which is blowing over the tops of the plants.
Concerned - Too much co2
With co2 being pumped into the room every hour (only when light are on), what kind of build up can I expect? I did a good job sealing the tent up, and the fan blows while the lights are on, 18-6 schedule. The tent has covered vents on 3 sides located at the bottom. The plants are on a table about 2'-6" above floor level and I know co2 is heaver then air.
Is the co2 being used by the plants and escaping out the vents by the blowing fan so the 1 minute co2 boost every hour is good? Or are the levels of co2 building and building every hour and poisoning my plants?
The answer is Sentinel Environmental Controller but that's $600 I don't have right now.
Any help/input with this would sure be great.
