wow this will work great for my situation rounding up money for a fewI just got some Pulse One hygrometers & VPD monitors in the mail. They sent me a couple to test out.
I will be setting these up shortly and will post pics and possibly some videos showing the setup and use of them.
I’ll update this thread over time and if you have any questions feel free to ask.
Kudos to https://getpulse.co/buy/ for the Pulse One tester units.
These will allow me to get my grow spaces dialed in perfectly as we all know how important VPD is to maintaining optional growing environments.

Light says 25%? 25% what?View attachment 859688
It actually measures: Temp, RH, VPD and Light. Pretty cool. I have them on my site TheGrowingShop.com and we drop ship from the manufacturer. But feel free to buy from their banner at the bottom of pretty much every page on THCFarmer :)

Here’s a leaf that just fell off. It’s late into flowering. As you can see there’s no signs of deficiency other than nitrogen which at week 7 is exactly what you want to see. The chlorophyll is gone completely. This leaf was green less than a week ago. Having the proper VPD has helped make this possible.

Here’s the backside. No purpling stem no blotches from magnesium or calcium deficiency. Just solid results.
Part of deficiency that most folks don’t realize is the lack of proper transpiration. If the plant is not uptaking moisture as quickly as it should then it won’t get the nutrients and micro nutrients it needs and then shows deficiencies when in reality the nutrients are there just not being mobilized due to a low VPD.
It’s just a fan leaf. The cola leaves are still green. It was a leaf that should have been defoliated but wasn’t. The main point I was trying to convey is that the plant is feeding properly and transpiring as it should due in part because the VPD is on point. Sure I could hit it with nitrogen but it’s less than a week from chop. I like to utilize the nutrients I add to the soil and not leave too much behind. No flush required just tap water the last week or so.
