These are so great not only for our own garden, but our customers love these as well.

I have come to realize that this VPD chart can help anyone in understanding what the air around our plants are experiencing conditions are. It’s also neat and clean to read and study from when in a pinch. Thank you to the team at pulse for offering this type of info that’s sophisticated enough to grab my pencils and papers and toss em into a drawer for now. Lol thanks

Like the size!
Perfect next to your Nutrient recipe charts

Chart arrived today in excellent condition. Such a cool tool to have around and avoid constantly opening a miniature image on the phone. Even included some sticker swag (always a bonus). Big props to John for keeping track of my shipment as USPS took this package on a frustratingly unexplainable journey that took weeks. That's life during COVID! Thanks again guys!

I really appreciate having this VPD chart in my grow. I reference it at least a couple times a day and since I started doing so the quality of my grows has only increased. Pulse rocks!
