Depending on the temperature inside the greenhouse, the moisture should be kept in line for the best results. For example, if the temperature is 24 degrees, %60 humidity is suitable. While too much moisture causes more illness in the greenhouse, too little of it can also be detrimental for the growth. The plant loses too much water, the growth stops and the shoots become shorter.
In the night, it’s ideal if the humidity in the greenhouse is low ( about %40 or %60 ). For this to happen, it’s important to have good ventilation and heating. In proper moisture condition, stem are longer, flowers and leaves are bigger, which means the quality is higher.
