Temperature & Humidity Control

Temperatures and humidity in grow rooms and grow tents is an important factor indoor growers have to consider to get the best possible growth rates and final yield. Hydroponic temps and humidity can be controlled and monitored using the devices we have listed in this collection of environmental hydroponic supplies. The measurement of both temps and humidity help growers figure out what kind of VPD the have. 

VPD is a measure of the difference between the amount of moisture in the air and the maximum amount of moisture the air can hold at a specific temperature. It's a critical factor in plant transpiration, affecting nutrient uptake, photosynthesis, and overall growth.
