9. Make Your Own Humidifier
Regulating humidity in your grow space is crucial. This ensures that your plants are getting enough moisture without creating a scenario where mold and fungus can grow. To get the right balance of humidity, use a simple, homemade humidifier.
Drape a towel over a hanger so that the bottom half of it is submerged in a bowl of water. As the towel absorbs the water, it will slowly release moisture back out into the air. Be sure you get a cheap hygrometer so you can monitor your room’s humidity levels.
