A general rule of thumb when it comes to VPD is
Seedling/Early veg 0.4-0.8 is ideal
Veg/Early Flower 0.8-1.1
Flower 1.1-1.3If VPD is not something you have ever thought to use in your garden, we highly recommend it. We do understand it can be challenging to achieve the perfect environment, but this at least gives us a goal to shoot for.
