We test everything we get our hands on in an effort to help customers know how to use the products they already have access to. Sometimes we consider using the products ourselves. This is a random test from a sample given to us from Emerald Cup.
We do not offer this product.
VPD helps you identify the correct range of temperature and humidity to aim for in your grow space. With VPD you can achieve the best results while avoiding pest and environmental problems. VPD also controls plant transpiration rates, stomata opening, CO2 uptake, nutrient uptake, and plant stress.
If you master VPD, you master your environment, and become better grower.
