The Quest 155 Return Duct Kit is a purpose-built ducting accessory designed for use with the Quest Dual 155 dehumidifier. It allows growers to connect return ducting to the unit so the dehumidifier can be installed remotely outside the grow room or grow tent while still pulling humid air from the cultivation space. This is particularly useful in indoor growing environments where space is limited or where growers want to reduce heat, noise and equipment clutter inside the grow room.
By enabling remote installation, the return duct kit helps maintain precise humidity control during vegetative growth and the flowering stage while keeping the grow environment organised and efficient.

How It Solves Grow Problems
Large dehumidifiers can take up valuable space inside a grow tent or grow room and can also add extra heat to the environment. This can make it harder to maintain stable humidity during the bloom stage, when excess moisture increases the risk of mould and poor bud density.
The Quest 155 Return Duct Kit allows growers to place the dehumidifier outside the grow room while still drawing humid air from the cultivation area. This helps maintain proper humidity levels without overcrowding the grow space, making it easier to manage airflow and climate conditions for strong plant health and improved yields.
How to Use
-
Turn off and disconnect the Quest Dual 155 dehumidifier before installation.
-
Attach the 12-inch return flange from the duct kit to the designated return air opening on the unit.
-
Secure the flange firmly using appropriate fixings.
-
Connect compatible 12-inch ducting to the flange.
-
Route the ducting from the grow room to the remotely placed dehumidifier.
-
Ensure all duct connections are sealed properly to prevent air leaks.
Once installed, the dehumidifier will draw humid air from the grow room through the ducting, helping maintain optimal humidity levels for healthy plants during both vegetative growth and flowering.
