Carbon dioxide (CO2) applications in indoor growing

Co2 In Plants

Carbon dioxide (CO2) applications in indoor growing

Carbon dioxide is essential to the process of photosynthesis. Most plants grown indoors require a minimum CO2 concentration of 330 mg/l to enable them to photosynthesise efficiently and produce energy in the form of carbohydrates. These concentrations of CO2 are enough for plants to grow and develop normally. Lower concentrations can seriously impede plant growth and general health. In fact, a drop of 25% in natural CO2 concentrations can easily inhibit growth by over 50%. Consequently, the grow room should be set up to replenish CO2 levels to at least 330 mg/l throughout the plant’s day time…….. Continue Reading
