Humidity is one of the most important aspects of a grow room, and there is a fine line between too much humidity and now enough humidity. Plants do best in humidity levels of 40-50% during veg and flowering, and slightly higher when propagating. If your moisture levels are too low or too high, it can have detrimental effects on your plants.
How do I know if I need a dehumidifier?
If you do not already have one, we recommend all growers keep a hygrometer in the grow room to help control the humidity. Many of these devices also contain thermometers, helping control the temperature simultaneously!
Do I need a commercial dehumidifier?
Commercial dehumidifiers are designed for use in a greenhouse or a large indoor garden. Whereas portable dehumidifiers are great for hobby farmers with small grow rooms, they are not well suited for maintaining moisture in the environment of a larger operation.
Whether or not you need a commercial dehumidifier will depend on your electrical system. Commercial greenhouses and warehouses often times use 208 Volt or 240 Volt plugs. This is to efficiently power a large system.
How do you size a dehumidifier for a grow room?
First, consider your growing space. How many gallons of water are you feeding plants daily? You will take this figure and multiply it by the number of plants in your system, and then convert this to pints (there are 8 pints in 1 gallon of water).
For example, if you have 20 plants, each needing 1 gallon of water a day, you will be working with 160 pints of water. Therefore, you will need a commercial dehumidifier capable of removing 160 pints from your growing space.
