Temperature fluctuations have an adverse effect on the growth of marijuana plants. Both higher temperature and excessive humidity bring about signs of stress in the marijuana leaves. The leaves turn yellow or brown with spots and burns exploding up. Owing to a very high temperature, the leaves closest to the light source gets burnt or curls upwards. Higher the humidity greater the dehydration in marijuana plants. The plant growth slows down at this level. Taking the right preventive measures solves the problem at the beginning stage. Allowing proper ventilation into the growing room is the right key to solving such environment-related issues.
To maintain optimum humidity, utilization of a dehumidifier for a closed system is an ideal solution. The cold pipes of the dehumidifier condense moisture and reduces humidity levels in the room. But the use of a dehumidifier increases the temperature of the room. Adding air vents to humidifiers prevents the rise in temperature. To maintain optimum temperature, use of an air cooler proves to be a good solution as it evaporates water and cools the room. It does not increase the moisture significantly thereby offering increased efficiency during the growth of the plants. Large bulbs in the growing room emit more heat which can be removed to avoid excess heat generation.
