Buying Guide of Best Dehumidifier for Grow Tent

Dehumidifiers come in a variety of sizes and capacities. You need to consider the following factors to choose the right one for your grow tent.

Floor Area Coverage

Grow tent dehumidifiers usually have a small area coverage, mostly limited to 200-250 square feet. Knowing the exact coverage area is crucial before buying the dehumidifier. It will ensure the device can efficiently remove moisture from the area.

A dehumidifier with a floor area coverage of 150-200 square feet will be fine for 4×4 grow tents. If you have a smaller grow tent, something like a 3×3 or 2×2, you may go for smaller dehumidifiers.

Moisture Removal Rate

It refers to the total amount of moisture the device removes from the area in a day. Most dehumidifiers for grow tents can remove 5-15 ounces of moisture every day, depending on the temperature and humidity conditions.

If the grow tent is bigger, you need to go with high-capacity humidifiers so that excess moisture can’t affect the growth of your plants.

Water Tank Capacity

The moisture drawn out from the room gets collected in a water tank until the tank is full. So, the water tank must have the capacity to hold enough water before stopping the device from working. This way, you need to drain the tank less frequently.

In most cases, water tanks have a capacity of two or three times the moisture removal rate. So, they can run for two or three days at a stretch. The bigger the tank, the less will be the hassle. But much bigger tanks may make the device heavy.

Features

Using a dehumidifier should be simple so that you can plug the device in and stop worrying. It should have indicators to let you know when the water tank is full and needs draining.

Most dehumidifiers have an auto shut-off feature, which allows the device to stop working automatically when the water tank is full.

It is better to have different working modes so that you can set the preferred mode depending on the humidity level. Thus, the working temperature range of the device should be broad.

Portability

Compact dehumidifiers are great for grow tents. They should be lightweight and portable so that you can move them easily. Most dehumidifiers come with a built-in handle for easy carrying.

Noise

The operating noise of a dehumidifier is often annoying. You should look for quiet dehumidifiers that run silently without a compressor. In that sense, small dehumidifiers for grow tents should never make a noise higher than 30-35 dB to be convenient.

Easy Cleaning

Accumulated dust particles inside an air filter can have adverse effects on plants. You should be able to remove the air filter to clean it regularly. In that case, you don’t need to buy a new air filter whenever it gets dirty.
