Where to Place the Dehumidifier in Grow Tent and Room

If you want to reduce excess moisture in your grow tent efficiently, you have to put the dehumidifier in the right spot and you can control the humidity.

Here are some general but essential tips on best placement and usage for dehumidifiers in grow tents:

  • Place the dehumidifier near the top of the tent, so it can pull in air from all sides.
  • Don't place it too close to the walls, as this can reduce its effectiveness.
  • Make sure the dehumidifier is not blocking any vents or air intakes.
  • Place the dehumidifier in an area with good air circulation.
  • Run the dehumidifier for several hours a day to maintain an optimal humidity level.
  • Keep the tent doors and windows closed when not in use.
  • Check the humidity levels regularly and adjust the dehumidifier settings accordingly.

Place the Dehumidifier near the Top of the Tent

The dehumidifier must be in the right spot for the best results. You can place it near the top of the tent, far away from heat sources and not near the floor.

This way, it'll be able to remove moisture from a wider area. Dehumidifiers work well in grow tents and rooms, but only if correctly placed.

Good ventilation is also a must. It helps exchange old, humidified air with fresh one and prevents plants from drying out. Don't place the dehumidifier over any plants, as it will block the air's circulation.

Place the Dehumidifier in a Sealed Grow Tent

Grow tents are sealed, so it can be hard to keep the environment inside ideal for plants. But, a dehumidifier can help!

To effectively dehumidify the tent, the dehumidifier should be placed outside the tent, as this will ensure better airflow and mixing of air in the space. Also, make sure it is the right size for the space is key to achieving optimal results. Don't forget to clean it out often, or mildew might form.

Finally, it's important to keep an eye out for moisture droplets forming on windows or the inside surfaces of your grow tent - this could indicate that you need a more powerful dehumidifier or additional ventilation. Get it right, and your plants will grow!

Place the Dehumidifier in an Open Grow Tent

Open grow tents are a cost-effective solution for indoor growers. Place the dehumidifier next to an exhaust fan and direct the air stream across the top of the tent. This draws in warm, moist air created when plants transpire and replaces it with dry, cool air from outside.

Make sure all edges are well-sealed to reduce clumping of hot, humid air. For best results, have the exhaust fan running at full throttle when the dehumidifier is on.

How to Lower Humidity in Grow Tent without Dehumidifier?

Searching for a way to reduce humidity in your grow tent without spending much money on electric dehumidifiers? Well, here are some tips for you.

Fans can help lower humidity in grow tents without the use of a dehumidifier. Different fan sizes, speeds and placements can assist with air movement and evaporation. This is efficient for gardens with multiple plants, as each requires different temperatures and air flows.

An oscillating fan at one end and another fan on the other create an "air curtain". This moves warm, wet air away from plants and brings in fresh, dry air. It's important to have separate fans at each end of the room, so plants get the best airflow.

You can seal off the grow tent with plastic or aluminum-backed greenhouse material. This traps the moisture-raising vapor inside, reducing water loss from the soil mix. Also, indirect lighting such as CFLs or T5s helps reduce heat and moisture transfer.

Finally, using desiccants such as silica gel or activated alumina may also be helpful in absorbing excess moisture from within the tent.

By taking these precautions, humidity can be lowered without needing a dehumidifier. However, in extreme heat or high humidity, a dehumidifier may be needed for the best results.

Final Verdict


A dehumidifier is an essential component to any grow tent setup. It helps to maintain the optimal humidity in your tent and keeps plants from becoming water-logged.

Choosing where to place the dehumidifier depends on a few factors, such as size, wattage, and type of dehumidifier being used.

Generally speaking, it is best located near the top of the tent for maximum efficiency. This will keep humidity at the optimal level and give your plants fresh air.
