CO2 Calculator for Grow Room or Indoor Greenhouse ...

To calculate the amount of CO2 you need, you’ll need to calculate the size of the grow room. For example, if you have a 8x8x7 foot grow room, you would need to cover 448 cubic feet (8x8x7=448). To compute the amount of CO2 required to raise the level to 1,000ppm use this equation: Width x length x height x desired CO2 level in parts per million.
