How to Choose the Best Grow Tent Dehumidifiers for Indoor Vegetation?

Selecting the best dehumidifiers for your grow tent can significantly impact your plants’ health and growth. The image below shows 7 factors you must consider when choosing the best dehumidifiers for your grow tent.

How to choose the best grow tent dehumidifiers
  • Size of the grow tent: The size of your grow tent will largely determine the type of dehumidifier you need. A small, portable dehumidifier may suffice for a smaller tent, but larger spaces may require a more powerful unit. Look at the manufacturer’s specified coverage area to ensure the dehumidifier suits your space.
  • Humidification capacity: This refers to the amount of moisture a dehumidifier can add to the air in a given period. It’s often measured in gallons per day. Make sure the dehumidifier you choose has sufficient capacity for your grow tent.
  • Control features: Some dehumidifiers have built-in hygrometers that measure humidity levels and automatically adjust output accordingly. Others may have timer functions or remote controls for added convenience.
  • Noise level: Dehumidifiers generate noise, which can be disruptive if your grow tent is in a living or working space. Look for models that operate quietly if this is a concern.
  • Maintenance and cleaning: Regular cleaning prevents mold and bacteria buildup. Choose a model that is easy to clean and maintain, with readily available replacement parts.
  • Energy efficiency: Consider the energy consumption of the dehumidifier. An energy-efficient model can save on electricity costs in the long run.
  • Price: Prices for dehumidifiers vary widely depending on their features and capacities. Balance your budget with your needs to find a unit that offers the best value for your money.

Should I Run a Dehumidifier in My Grow Tent?

Yes, you should run a dehumidifier in your grow tent since it’s beneficial, especially in humid climates or during specific growth stages. Excess humidity can lead to problems like mold and mildew, which can damage or kill your plants. A dehumidifier removes moisture from the air, helping to prevent these issues.

What Types of Dehumidifiers Are Out There?

There are primarily four types of dehumidifiers, each with its unique way of removing moisture from the air:

1. Refrigerant (or compressor) dehumidifiers: These work by drawing moist air over a refrigerated coil with a fan. The cold coil condenses the moisture in the air into water, which is then collected in a tank. This type of dehumidifier is most effective at higher temperatures and higher humidity levels.

2. Desiccant dehumidifiers: Instead of using a coil to condense moisture, these use a desiccant – a material that naturally absorbs water. As the desiccant absorbs moisture from the air, it gets heated to remove the moisture, which then gets collected in a tank. Desiccant dehumidifiers are particularly effective in cooler climates or areas with lower temperatures.

3. Whole house dehumidifiers: These are larger units that connect to your home’s HVAC system to reduce humidity throughout the entire house. They work similarly to refrigerant dehumidifiers but on a larger scale.

4. Mini dehumidifiers: Also known as compact dehumidifiers, these are smaller, portable units ideal for small spaces like bathrooms, closets, or grow tents. They can operate either as a desiccant or refrigerant dehumidifier.

How Do You Find Dehumidifiers’ Sizes Based on Grow Tent Sizes?

Selecting the right size of a dehumidifier for your grow tent depends on the size of the tent and the humidity level.

The table below provides a general guideline you can follow to find the size of dehumidifiers:

How Do You Find Dehumidifiers' Sizes Based on Grow Tent Sizes?

Remember that these are just estimates, and other factors like plant density, climate, and the specific humidity needs of your plants should also be considered.

It’s always better to opt for a slightly larger capacity than needed. This ensures that your dehumidifier can handle spikes in humidity and won’t have to work as hard, extending its lifespan.

What Are the Energy Efficiency and Running Costs of the Grow Tent Dehumidifiers?

The energy efficiency and running costs of grow tent dehumidifiers can vary significantly based on their type, size, model, and how often they’re used. However, here are some general points to consider:

  • Energy efficiency: Dehumidifiers are rated for their energy efficiency using an Energy Factor rating, measured in liters of water removed per kilowatt-hour (kWh) of energy used. The higher the Energy Factor, the more efficient the dehumidifier. Many modern dehumidifiers also come with an Energy Star certification, indicating they meet certain energy efficiency criteria set by the U.S. Environmental Protection Agency.
  • Running costs: The cost of running a dehumidifier depends on its power consumption (in watts), the local electricity rate, and how long it’s operated daily. For example, if a dehumidifier uses 500 watts, operates for 12 hours a day, and the electricity rate is $0.10 per kWh, the daily cost would be $0.60.
  • Other factors: The size of your grow tent, the amount of moisture in the air, and the desired humidity level can all affect how hard your dehumidifier needs to work, impacting its energy use and cost.

Where Should You Put Dehumidifiers in Grow Tents?

The placement of dehumidifiers in grow tents can depend on three factors: the tent’s size, air movement, and the specific model of the dehumidifier.

For small grow tents, dehumidifiers can be placed directly on the floor or outside of the tent near the intake fan. This placement allows maximum air circulation, especially when placed low and near the intake fan. However, ensure that the dehumidifier is out of the way of potential issues with the spilled water.

Alternatively, if your grow tent has enough space, you can place the dehumidifier near the top of the tent, away from heat sources. Some dehumidifiers can also be suspended from the ceiling to save space.

How to Use a Dehumidifier?

You should follow these 5 steps below to start using the dehumidifier:

1. Choose the right location: Place your dehumidifier at least a few inches away from walls and furniture for adequate airflow. Avoid areas near sources of dust or dirt that could clog the filter.

2. Set the humidity level: Best dehumidifiers have a control panel where you can set the desired humidity level. A typical target is between 30% and 50% relative humidity. The dehumidifier will then run until it achieves this level.

3. Empty the water reservoir regularly: Dehumidifiers collect water in a reservoir that must be emptied regularly. Some models switch off automatically to prevent overflow when the reservoir is full. If you don’t want to empty the tank manually, consider a model with a continuous drain option.

4. Clean the air filter: Best dehumidifiers have a removable air filter that traps dust and other particles. Cleaning this filter regularly can help the dehumidifier work more efficiently and prolong its lifespan.

5. Keep doors and windows closed: To maximize efficiency, keep doors and windows closed in the area where you’re using the dehumidifier. This prevents new humid air from coming in.

The image below outlines 5 simple steps to start using the dehumidifier properly.

How to Use a Dehumidifier?

How to Maintain a Dehumidifier?

Maintaining a dehumidifier involves 5 steps to ensure it operates efficiently and lasts as long as possible:

1. Empty and regularly clean the water tank: The collected water should be emptied regularly. If left for too long, it can breed bacteria and mold. Wash the tank with soap and warm water weekly to keep it clean.

2. Clean or replace the air filter periodically: Best dehumidifiers have air filters to capture dust and allergens. Depending on the model, these filters must be cleaned or replaced every few months. Refer to your user manual for specific instructions.

3. Clean the coils: Over time, the dehumidifier’s coils can accumulate dirt and dust, reducing efficiency. To clean them, turn off and unplug the unit, remove the outer casing, and gently clean the coils with a soft brush or vacuum.

4. Inspect and clean the grills and louvers: These should be cleaned to remove dust or dirt. A vacuum cleaner with a brush attachment can be used for this task.

5. Store properly when not in use: If you aren’t using the dehumidifier for an extended period, clean it thoroughly, ensure it is dry, and store it in a dry, cool place. You might also want to cover it to prevent dust accumulation.

How to Dehumidify a Grow Tent Without a Dehumidifier?

  • Improve ventilation: Proper airflow can help carry moisture out of the tent. Using fans or installing an exhaust system can greatly improve ventilation.
  • Control temperature: Higher temperatures can hold more moisture. You can reduce the relative humidity by lowering the temperature in your grow tent.
  • Use absorbent materials: Certain substances like silica gel, calcium chloride, or rock salt can absorb moisture from the air. Place these in a container inside the tent to help lower humidity levels.
  • Water wisely: Overwatering plants can increase humidity. Water your plants only when necessary, and try to do so when the lights are on, as this helps the water evaporate more quickly.
  • Increase plant spacing: If plants are too close together, they can create a microclimate with higher humidity. Spacing your plants out can help reduce this effect.

The image below lists 5 ways to dehumidify a grow tent without a dehumidifier.
