This dehumidifier is completely different from the others on this list.  Instead of using electricity, fans, and motors to draw the moisture out of the air and into a water tank, it uses silica gel. 

This is something that you will be familiar with if you have ever had to dry out a phone or have ever bought shoes.  

The silica gel absorbs all the moisture from the air inside your grow tank.

It also makes a great backup option to keep in case your larger, electric dehumidifier fails at any point.  

As the silica gel absorbs moisture from the air it will begin to darken.  When it turns dark, you simply have to ventilate the canister.  When the gel turns orange again, you can reuse the canister with the same gel. 

What’s more, the canister is super lightweight and portable which means you can reposition it within your grow tent whenever you need to. 


  • No risk of spillage
  • Silica gel recharges fast
  • Super affordable
  • Can handle a large grow tent area


  • The material of the canister is super easy to dent

Buyer’s Guide

Purchasing the correct dehumidifier for your grow tent is crucial to ensure that your plants thrive and produce a strong crop of flowers.

Dehumidifier Range

The range is one of the most important things to keep in mind when looking for a dehumidifier for your grow tent.  While it might be tempting to opt for the dehumidifier with the largest range, the potential is wasted if you are going to put it in a small grow tent.  

The range of the dehumidifier also often corresponds to the size of the unit itself.  You don’t want a dehumidifier that is so big that it will be touching and cramping your plants. 

Dehumidifier Tank

The tank size of a dehumidifier device is another important factor to take into account before making a purchase.  Often, the range of a dehumidifier and the size of the dehumidifier tank are closely related.  

The bigger the range, the bigger the unit, and the bigger the tank.  It is important to make sure that the tank on your dehumidifier is large enough to contain the amount of moisture that needs to be removed from the air.  

The tank should also be large enough to cope with not being emptied on a daily basis if you are likely to be away from home for a couple of days. 

If you do not have room for a dehumidifier that has a large enough tank to go a couple of days without being emptied, investing in some silica gel dehumidifiers for the duration of trips can be a good backup. 

Cooling Method

The cooling method is another important thing to consider before investing in a new dehumidifier.  Many dehumidifier devices use motors and fans to remove moisture from the air.

This is a tried and true method, however, it does mean that the devices can be quite noisy when they are being used which is likely to be constant for a period of time.  

If your grow tent is in an area of your home where the noise would be inconvenient, it is worth looking into devices that use Thermo Electric Cooling Technology to remove the excess moisture from the air. 

These types of dehumidifiers are almost completely silent, especially when shut inside a grow tent.  

If even a small amount of noise is going to be disruptive due to the location of your grow tent, a final option is to purchase a silica gel canister dehumidifier. 

This is completely silent and is incredibly effective at removing excess moisture from your plants. 


Finally, portability is a huge consideration for your dehumidifier.  If you have never grown cannabis before, there is a chance that you will have to experiment a little bit with the ultimate positioning of your dehumidifier. 

The smaller and more portable your dehumidifier is, the easier it will be to move the device around to get the most out of it.  

The lighter and smaller your dehumidifier device is, the more options you have for positioning too.  Many of the smaller dehumidifier devices come with hooks built into them which allows you to experiment with hanging your dehumidifier in your tent.
