You’ve allocated the required space, you’ve hooked yourself up with some decent lighting technology and you’ve bagged the best seeds money can buy. All that stands between you and a huge harvest of quality cannabis being careful humidity control.

Well, perhaps not only humidity control, but it’s an important contributor to the final result!

Evidence would seem to suggest that humidity is one of the most commonly overlooked factors that can affect an indoor grow space. Despite being surprisingly easy to take control of.

So for those who’ve always just assumed controlling humidity levels is an epic task, here are five simple yet effective ways to get the job done:

1. Seal and Insulate Your Room

First up, the key to success with an indoor grow space is to create a stable and consistent environment. It’s one thing to allow air to enter the space from elsewhere, but this can make it difficult to meticulously monitor and control temperatures and humidity. The humidity outdoors inherently affects the humidity in your grow space if it isn’t appropriately sealed. Hence, the first step in the process is to seal and insulate your grow space, completely cutting it off from outside influences.

2. Keep a Close Eye on Temperatures

Fluctuations in temperature can cause significant and ongoing problems with humidity. The problem being that many indoor growers take things to extremes, installing powerful heaters and air conditioners they’ve really no need for.It’s a case of keeping things as balanced as possible at all times, preventing things shifting from hot to cold (and vice versa) too quickly. Strategic temperature control makes humidity control exponentially easier.

3. Keep the Air Moving at all Times

It’s very rarely still outdoors, so you need to replicate these conditions indoors.Simply setting up a couple of oscillating desk fans around the room can be enough to make all the difference. Air that isn’t well circulated quickly becomes dank, stale and downright dangerous for your plants. Focusing on air movement is a great way of simplifying humidity control, while at the same time ensuring your plants are provided with a healthy hit of fresh air from top to bottom.

4. Be Aware of Standing Water

Any standing water around your grow space is guaranteed to have an impact on humidity levels. Where the growing medium remains wet due to poor drainage, some of this residual moisture will make its way into the air. If you have open reservoirs about the place, evaporation is inevitable. Humidity levels in an indoor grow space become significantly easier to control when standing water is reduced or eliminated where possible. Exercise the necessary measures to improve drainage and cover open reservoirs.

5. Use a Dehumidifier

Last but not least, it’s rare for indoor cannabis cultivators to struggle with humidity levels that are too low. Increasing atmospheric humidity is relatively easy - decreasing humidity levels typically calls for help. And by help, we mean the installation of a decent dehumidifier. One of the most indispensable tools for the keen cannabis cultivator, dehumidifiers (used properly) make it incredibly easy to keep excess humidity at bay. It’s simply a case of keeping a close eye on things as you go, in order to avoid taking things too far and drying-out the air.
