CO2 enrichment

If you are green to gardening you might not know that carbon dioxide, the gas we all exhale, is critical to plant growth and development. Photosynthesis, the process through which plants use light to create food, requires carbon dioxide. CO2 concentration in ambient air ranges from 300-500 parts per million (ppm), with a global atmospheric average of about 400 ppm. If you are growing in a greenhouse or indoors, the CO2 levels will be reduced as the plants use it up during photosynthesis. … [Read more...] about Managing Carbon Dioxide in Your Grow Space
