Passive CO2

Definition - What does Passive CO2 mean?

Passive CO2 as the name suggests has to do with carbon dioxide in plants, particularly in an enclosed environment. Passive CO2 enables photosynthesis by penetrating through the leaf pores. The concentration of carbon dioxide in the growing environment greatly affects the growth of a plant, desired levels of passive CO2 helps plant growth, while lack thereof can be a plant growth deterrent.

MaximumYield explains Passive CO2

Since carbon dioxide is a crucial part of photosynthesis in farming, passive CO2 is used to increase CO2 supplementation and consequently increase the yield of plants in a controlled environment farm. Passive CO2 is a favored supplement CO2 in indoor farms due to its affordability and return on investment. It is a budget-friendly and less-heat generating way to provide plants with a higher amount of carbon dioxide than what is generally present in an indoor environment. Passive CO2 can be found in the form of fungus in bags or sheets of fabric.

CO2 enrichment, triggered by passive CO2, can increase the production of plants and make indoor farms more efficient. Passive CO2 catalyst products release CO2 slowly into the environment and ensure plants are able to acclimatize with the change. There are commercial and DIY passive CO2 options available. But, the DIY options (involving things like dry ice, baking soda, vinegar etc.) are not as effective or efficient.
