CO2 Grow Room Calculator
Calculate the volume of CO2 gas injections required to raise grow room concentrations to optimal plant levels.
Input Parameters
Enter details for calculation.
Gas Injection Time
Expert Tip
Most plants grow best when ambient CO2 levels are boosted to 1200 - 1500 ppm, but only under high PPFD light and rich water/fertilizer cycles.
Calculation Methodology & Details
Formula
The calculator estimates how much pure CO2 must be added to a sealed grow room volume to achieve target levels. 1 ppm is one-millionth of the total room volume.

How to Calibrate Grow Room CO2
Follow these steps to schedule CO2 enrichment injections:
Calculate Room Volume
Multiply length by width by height to get total room size.
Define Target Levels
Set current (usually 400 ppm) and target values (usually 1200 - 1500 ppm).
Check Regulator flow
Identify the flow rate of your gas regulator valve (CFH or LPH).
