This may be my second review

Recently I was showing some info to a client in a video that shows the Pulse VPD poster on my dining room wall at home, well the owner mused that he’d like one at each of his multi state operations. Pulse was quick to help me get one to each. They are a great American business to work with

Appreciate the kind words and support Steven! Glad we were able to get your client setup with some charts!

VPD Charts

Charts looking very good. They are a good way to familiarize for growers who doesnt understand a lot of VPD. For growers that knows about VPD and his benefits its a tool for a faster recognize of the transpiration rates of the crop.
The clients love it! in Chile we doesnt have a lot of space yet and the posters are very large for some people but always has his place in the grow building.
Thank you guys!
