Why do Cannabis Plants Need CO2?
Like all green plants, cannabis relies on photosynthesis to convert CO2 and water into carbohydrates for growth. If a cannabis plant doesn’t receive enough CO2, its growth will slow down once its stored sugars are depleted. On the other hand, too much CO2 can hinder photosynthesis. The ideal CO2 level for a grow space depends on maximizing photosynthesis and yield.
During photosynthesis, cannabis plants absorb CO2 through tiny openings called stomata on their leaves. The CO2 is then used in combination with light energy and water to produce glucose, which is essential for plant growth and development. Without sufficient CO2, the plant’s ability to produce glucose is limited, resulting in stunted growth and decreased yield.
Why is photosynthesis important for cannabis plants?
Photosynthesis is the process by which plants convert light energy into chemical energy. It is a vital process for cannabis plants as it provides them with the energy they need to grow, flower, and produce fruits or flowers. Without photosynthesis, cannabis plants cannot produce enough glucose to support their metabolic processes and ultimately, their survival.
“Photosynthesis is the driving force behind plant growth and development. Without a sufficient supply of CO2, cannabis plants cannot perform photosynthesis efficiently, leading to reduced yields.”
In addition to producing glucose, photosynthesis also releases oxygen as a byproduct, which is vital for the overall health of the grow space. By maintaining the right CO2 level, growers can ensure optimal photosynthesis, leading to healthier and more productive cannabis plants.
