High Humidity Problem

High levels of humidity can cause kinds of problems for indoor cultivating, you need a grow room dehumidifier.

1. Powder Mildew

Many fungi like to grow in high-humidity environments. Molds and fungal spores will multiply and spread through the air or water, easily infect plants and affect the quality and yield.


2. Weaken Nutrients Absorption

Plants generally use transpiration to absorb water for healthy growth. High humidity will weaken the transpiration of plant leaves, which will decrease the plant’s ability to absorb and transform nutrients.


3. Affect Respiration & Photosynthesis

High humidity will also condense the leaf surface water, which will seal the stomata and weaken respiration, and maybe stop their photosynthesis, and then the yellow leaves will appear.


4. Cause Some Unsafe & Unstable Factors

High humidity will also cause water droplets on the top and wall of the to grow room, which will also cause some unsafe and unstable factors.

Why Choose Altaqua grow room dehumidifier


Product Capacity

Based on the same standard @80.6℉, 60%RH, our grow room dehumidifier capacity is far greater than


Technical Parameters

Altaqua Advantages

Technical data based on medium temperature and medium humidity @ 80.6F, 60%RH

Especially for grow rooms, medium temperature, and humidity 80 F, 60%RH, very close to the ideal growing environment, and apparent dehumidifying capacity in daily operation.

These medium temperature and medium humidity designed standard conditions can operate stably while temperature and humidity are low.

To handle humid air at a lower temperature need a much lower evaporating temperature, need a lower dew point, which means a lower inlet temp, need a higher standard for refrigeration system design, and greater difficulties.


Technical data is mostly based on high temperature and high humidity @ 86F, 80%RH

× Unit is designed based on 86 F, 80%RH, working conditions, mainly used for industrial places and home applicants.

× As to its high temp & high humidity designed standard condition, it can't operate stably while temperature and humidity are low. Even if it stops while the return air temp reaches 15 C to defrost, humidity increases rapidly along with the frost melting.

× You will only get almost half capacity in a normal growing environment 80F, 60%, while you buy a nominal unit capacity of 500 [email protected], 80%RH. That won't happen if you use our unit.
