What is a dehumidifier?

A dehumidifier is an electrical appliance that controls the humidity level in your grow tent. This ensures the growing area does not have too much moisture that can cause mold. When humidity is too high, the health of your plants will be negatively affected. To avoid frustrations in your indoor farming, you should choose the best dehumidifier for grow tent.

How to set dehumidifier in grow tent

Depending on the air movement, you can place your dehumidifier inside or outside the grow tent. Knowing where to place your unit will reduce the risk of humidity spikes where mold can take over. Two factors affect where you place your dehumidifier: the size of the tent and RH. Young plants require relative humidity (RH) of 60% while flowering plants need RH of 40%. Also, grow tents require different temperature ranges.

This brings us to the question, how do you place a dehumidifier? You should place the unit above the lights. If you use more than one dehumidifier, be sure to leave even space between them. Make sure the filter faces the inside part of the room to drain properly. Another factor that affects the perfect set of considerations is capacity. Plants will release almost all the water. Do your math and use a powerful unit for the grow tent.

After analyzing your situation, you can also place the unit outside the grow tent. You may choose a whole room or a ducted dehumidifier. Since the grow tent is placed inside the room, it will take in all the air. For ducted dehumidifier, you’ll need a box cutter, duct tape, cardboard box, insulating duct, and flanging kit.

Next, find a board to hold the dehumidifier and place it near the power source. You may need extra wiring to power up the unit. Place the dehumidifier inside the box and connect an insulating duct tape on the other end. This will link the grow tent intake fan and the box. Once you secure all the connections, you can power up the dehumidifier.

No matter the unit your purchase, be sure to stick to the right installation method. If your grow tent is limited on the floor area, you should go for a suspended installation. You must install the unit with a set of brackets. The best dehumidifiers for this type of installation are compact in size and remote-controlled. For long-in-shape dehumidifiers, you should go for freestanding installation. In this method, checking for settings and troubleshooting is much easier. If you’re limited on space, you should choose the ducted installation.

You have to ensure that all the air in the grow room is close to the dehumidifier. Since a typical grow room dehumidifier can take about 800 cubic feet of air, you may want to select a unit that caters to your needs. A grow room is somewhere between 100-500 sq. feet. Why is this important? If the grow room is above 350 square feet, you should ensure you have a separate unit for 250 square feet space.
