Greenhouse CO2 Requirement Calculator
Calculate CO2 supplementation needs for greenhouse
About this calculator
The Greenhouse CO2 Requirement Calculator helps greenhouse operators determine the optimal amount of carbon dioxide supplementation needed to maximize plant growth and yields. By calculating precise CO2 requirements based on your greenhouse size, crop type, and environmental conditions, this tool ensures you provide the right concentration for photosynthesis enhancement while avoiding waste and controlling costs. Proper CO2 supplementation can increase crop yields by 15-30%, making this calculator essential for commercial and hobby greenhouse management.
How to use
Enter your greenhouse dimensions (length, width, height) and select your crop type from the dropdown menu. Input your current CO2 levels and desired target concentration (typically 800-1200 ppm for most crops). The calculator will determine the required CO2 flow rate and daily supplementation amounts needed to maintain optimal growing conditions.
Frequently asked questions
What is the ideal CO2 level for greenhouse plants?
Most greenhouse crops thrive at 800-1200 ppm CO2, which is 2-3 times higher than atmospheric levels (400 ppm).
When should I supplement CO2 in my greenhouse?
CO2 supplementation is most effective during daylight hours when plants are actively photosynthesizing and vents are closed.
How much can CO2 supplementation increase yields?
Proper CO2 supplementation typically increases crop yields by 15-30%, with some crops showing even greater improvements under optimal conditions.
