In indoor gardening and greenhouse processes, a certain level of humidity is required and, in some cases, desirable. However, a balance needs to be achieved in that process. For instance, too much humidity can lead to your plants suffering from some serious damage. If your grow room temperature increases your plants' moisture level, you need to use a dehumidifier.

What is a Dehumidifier?

If you are familiar with a humidifier, then dehumidifiers do the exact opposite. As the name suggests, a dehumidifier is a tool that helps remove moisture from the air and bring it to a desirable level.

When your room has high humidity levels, it can cause mold and bud rot on your plants. It can also slow down the growth of your plants very significantly.

Perfect Humidity Level for Your Grow tent / Grow Room?

plants have different needs when it comes to humidity levels based on what stage of growth they are in. Clones and seedlings require very high humidity levels upto 75%. During veg, a 50-70% humidity is ideal and during flower, the humidity needs to be lower 40-50% is optimal, and this should be maintained throug harvest.

While dehumidifiers have plenty of benefits when it comes to indoor growing, if you are using a hydroponic system, then they are essential. To help control the room's humidity levels, you need proper ventilation, so be sure to use a blower or a fan.

What Dehumidifier Size do I need for my Grow Tent / Grow Room?

The size of a dehumidifier is based on how many pints you need removed. All you need to is use a simple equation to find the right size.

[gallons/day per plant] x [number of plants] x 8 [gallons to pint factor] = [recommended dehumidifier performance]

At Groindoor.com, we have everything for everyone. If you are a commercial grower, we have large commercial dehumidifiers, and if you are a hobby grower, we recommend buying the smaller, more portable dehumidifier.
