1、 Principle

Closed cultivation is a short-term cultivation method, which is also a popular saying. The principle is to cover the plants with transparent glass or plastic to create the greenhouse effect. If the cover is covered to seal the space, the temperature inside can rise, form a large temperature difference with the actual temperature, and also improve the humidity. Through this method, the plant can change its shape in a short time, accelerate its growth speed, and make the plant grow watery, The leaves become bright and bright, and the effect is still very obvious. It is usually carried out in spring and autumn. It cannot be selected in summer, which can not play its due effect, and it will also cause damage to the plant itself

2、 Precautions

1. It is not necessary to cover the stuffy cultivation all the time, but to uncover it for ventilation. Pay attention to ventilation and ventilation every day

2. We should also pay attention to proper watering. Proper supplement of water is helpful for growth. The soil should not be too dry to avoid affecting its own growth
