CO2 calculations...

1. Measure and multiply:length x width x height of your grow room to calculate the volume of cubic feet

2. Relatively, the CO2 level in a grow room is 300 ppm. To bring your room to an optimum level of 1 500 ppm, you will need to raise the CO2 by 1 200 ppm.

3. Multiply your room volume by 0.0012 (1 200 ppm = 0.0012) to determine how much CO2 to add to your grow room.

EXAMPLE: a 10' x 8' x 10' room:

1. Volume= L x W x H
volume= 10 x 8 x 10 = 800 cubic feet

2. 800 cubic feet x 0.0012 =.96 cubic feet-- you can round this to 1 cubic foot. You will therefore need to add 1 cubic foot of CO2 to a 10 x 8 x 10 grow room to bring the CO2 level to 1 500 ppm.
