If you are growing in a large warehouse or grow room, you likely need a commercial grade dehumidifier. Without one, you run the risk of excess moisture compromising your grow, costing you far more than one of these dehumidifiers would have.
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 during propagation. If your moisture levels are too low or too high, it can have detrimental effects on your plants.
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 grade 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 does a commercial dehumidifier work?
Commercial grade dehumidifiers work in the same manner as most dehumidifiers - just on a much larger scale. The unit will suck in hot, moist air with a fan. This air then crosses over the dehumidifiers refrigerant cooled coils.
This leads to the moisture condensing on the coils, and the dry, cool air is expelled from the dehumidifier back into the growing space or into a separate zone, such as outside or into the ceiling.
There are different ways you can set up your grow room dehumidifier, with ducting or ductless. It comes down to what works best for your grow. If you have questions, reach out to our experts.
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.
