c02 light cycle questions

[JeffersonBud]

1500 ppm is the optimum level of c02 you need. Once again, 300 ppm is in the atmosphere already so your co2 regulator will need to pump out 1200 ppm over time

There are Co2 auto calculators online. just search google for one. My room is 4x8x6 is sealed. My co2 runs at 1 bar for 13 minutes to reach 1500 ppms( the air already has 300 ppms of co2 so you need to calculate for 1200). I add another 2 minutes just to make sure it hits that 1500 mark. It fires every 3 hours when the lights are on.

how many bars does your regulator go to? if it is 1 like mine then you will need more then 13 minutes because your room is much larger.

Thanks for the info Jefferson you da man.

Measured my room...

It's 960 cubic feet.

The main area is 7.5 feet, height is 7.5 feet, width 11.75 feet.

Also a little closet area that wasn't measured in the main roon is

3.5 feet deep, height 7.5 feet, 6.0 feet in width.

For the calculator I used online it says 960 cubic feet will get filled to 1500 PPM with 23 minutes of co2 being emitted at a rate of 2 cubic feet per hour.

Do most regulators have several release rates? I would have to imagine so.


So now, I will release it for 23 minutes..and then would you guys reccomend leaving my exhaust off for an additional 10 minutes or so if the heat doesn't become a problem?

Last time I checked I could leave my exhaust off for 32 minutes before the temperature exceeded 85 in the canopy.
