How Quest Overhead Dehumidifiers Works

Getting your environmental parameters within optimal ranges is the key to successful growing. Relative humidity plays a huge role in dictating the growth rates of your plants. When humidity levels are too low, the rate of transpiration increases, causing the plant to lose too much water. Likewise, when humidity levels are too high, growth rates slow down dramatically, and the door is also opened up to an array of moisture-related issues, like powdery mildew and botrytis (rot). As plants reach their later stages, they can put a lot of water vapour into the surrounding atmosphere, and if humidity levels in the room are still too high, then you're going to need some extra help.
