How To Choose The Best Dehumidifier For A 4×4 Grow Tent

This is an expensive machine so you would not want to waste your money by choosing any random dehumidifier from the store.

This is a good practice to understand a few crucial pieces of information about a dehumidifier as it helps to understand some essential features that you should look for in a good dehumidifier.

Which Size Dehumidifier is Best For A 4×4 Grow Tent?

A 4×4 grow tent is good for the cultivation of 6 to 8 plants in 3 gallons of grow bags. Choosing the right size dehumidifier for such a small grow tent is not so difficult.

For a 4×4 grow tent you need to maintain at least 40%RH to get the best result. Here in this article, I’ve listed some best value-for-money dehumidifiers that will not hurt your bank.

Power Consumption

This is one of the very important criteria that can save you lots of money after purchase although it will cost you a little bit more by going with some best brands. To maintain the 40% RH you don’t need to spend on a big-size dehumidifier if you don’t want to install a big-size grow tent later on.

Water Tank Capacity For 4×4 Grow Tent

A 4×4 grow tent doesn’t require such a dehumidifier that comes with a large size water tank. A dehumidifier with up to 1500 ml capacity is more than enough according to the size of your small grow tent. A dehumidifier that has a moisture-removing capacity is around 350ml/day is sufficient for your need.

User Friendly And Easy To Use

A dehumidifier must have easy-to-operate features. Some cheap dehumidifiers come with very limited functions and you need to spend extra on other tools to measure the humidity of your grow tent.

On the other hand, some feature-rich dehumidifiers come with advanced features such as automatic on/off, humidity checks, and adjustment mechanisms.

Best Dehumidifier For 4×4 Grow Tent (FAQ)

1. How do I lower the humidity in my 4×4 grow tent?

There are so many ways to lower the humidity of your 4×4 grows tent with a dehumidifier or without a dehumidifier such as:
1. Don’t pour too much water into the plant. The excess water leads to an increase in the water concentration in the air which leads to an increase in the humidity level in your grow tent.
2. Use some fans to regulate the airflow inside the grow tent. Install some exhaust fan that throws the inside humid air outside and intake the fresh air with lower RH.
3. Use a dehumidifier which is one of the best ways to maintain the humidity in your grow tent on per regular basis.
4. Use a proper drainage system to prevent water stagnation.
5. Seal your grow tent properly to ensure that the outside atmosphere can not affect the inside.

2. How big of a dehumidifier do I need for my 4×4 grow tent?

Every company defines an area for its dehumidifier in which it performs well. Always buy a dehumidifier that can cover a larger area than your requirement.
Example: As the size of your grow tent is 4×4 which means its size in square feet is 16 square feet a dehumidifier that covers at least 100, 256 square feet of area is more than enough for your need, you don’t need to go with a high capacity if you don’t want to upgrade the size of your grow tent in future.

According to my research, I found that the 2 best dehumidifiers are the best in the market right now for different purposes.
