What Should You Know About Grow Room Dehumidifiers?
Effects Of Too Much Moisture In Your Grow Tent
Too humid air in your grow room can have a detrimental effect on your crop and lower its yield. The most common conditions linked to high humidity levels are root rot and different types of mold such as powdery mildew and bud rot.
Effects Of Too Little Moisture In Your Grow Room
Too little humidity is also bad for plant growth. If the humidity in the growth room is lower than 30% RH the transpiration ability of the plant is diminished and that slows down the growth of the plant. Low humidity also disrupts the process of photosynthesis. So don’t run your dehumidifier too much!
What Is The Ideal Humidity Level In A Grow Room?
The ideal humidity in your grow room depends on a lot of factors, one being the stage of the plant’s life. If your plants are in the seedling or clone phase, they need higher humidity, from 70 to 75%. Vegetating plants need the humidity from 50 to 70% and flowering plants need 40 to 50% relative humidity.
Choose The Right Size Dehumidifier For Grow Tent
When choosing a grow tent dehumidifier make sure to size is well. The size of the dehumidifier depends on the size of your tent, the number of plants you are growing, on how often and how much do you water them. It also depends if the grow tent has ventilation and if people are coming in or not.
