6. Increase the concentration of CO2 around the CO2 concentration of zucchini plants below 300mg/l, you can increase the concentration of CO2 in the shed or CO2 fertilization by ventilation and air convection. When the concentration of CO2 in the shed is higher than that of 1800mg/l, proper release can be done.
