CO₂ Grow Room Calculator

Find CO₂ needed to enrich a grow room.

CO₂ to add 0.32

CO₂ to add 9.061

Formula: CO₂ ft³ = room volume × ppm ÷ 1,000,000

Step-by-step with your numbers:

1. Values used:

2. Room volume = 320

3. Target increase = 1,000 ppm

5. CO₂ to add = Room volume / Target increase = 320 / 1,000 = 0.32

6. CO₂ to add = 9.061

Estimate CO₂ to raise a grow room's concentration for faster plant growth.

The math behind it

CO₂ volume = room volume × (target ppm increase ÷ 1,000,000).

320 ft³ room, +1000 ppm → 0.32 ft³ CO₂.

Safe levels?

1,000–1,500 ppm helps plants; keep well below human-hazard levels and ventilate.
