Dehumidifying Marijuana Grow Room

Dehumidify your marijuana growing room because in a hot, dry climate will have narrower leaves than cannabis grown in a humid atmosphere.

The logic behind that theory is in a dry atmosphere the plant’s respiration will be easier as the moisture on the leaves evaporates faster.

In a humid atmosphere, the moisture cannot evaporate as fast. This leads to a simple conclusion of getting a humidity gauge and maintaining a dry level.

A dry level is best determined by experimenting with different levels to see how the plants respond to your particular grow room conditions.

In good growing conditions, the leaves must be broader with more surface area to expel the wastes that the plant will put out. Since the broad leaves produce less resin per leaf than the narrow there will be more resin in an ounce of narrow leaves than in one ounce of  broad leaves.

This makes for excellent THC oil production by those who love honey oil.

One of the purposes the resin in the marijuana plant serves is to keep the leaves from drying out. There is more resin produced in a dry grow room than in a humid area.

Dehumidifiers cost around $100.00 to $300.00 and is well worth the investment for those rooms with wet walls and humid windows.

    • 40-70% Relative Humidity. Drier air can lead to pest problems like spider mites, near 80% you are are almost guaranteed mold and powdery mildew.

      Generally speaking I try to keep it high toward the beginning, while growing vegetation and in early flower, then nearer 40% for the last few weeks to encourage more resin.

      You then need to go up a bit for the drying so that doesn’t happen too fast.

      Or, like many people, you use various methods to control the problems since that is cheaper than a $5000 air conditioning, heating, and humidity control system ;)


Have your say!
