Hi guys.
I have been focusing on The VPD in my tent. Trying to stay in that sweet spot at all times.

I am running COBs in my tent so I have my temps at 82-84F. I have leaf temps of 77-79F on the plants. My RH is 64-68%. I am still in Veg.

I have found many charts online showing where I should be.
But most of them are slightly different.

I belive Most the difference is some show room temp some show leaf temp.

Any of you guys have a dependable chart that you use?

Search for a VPD calculator so you can enter in the specific variables of your environment and redraw the chart.
The static charts will make slightly different assumptions as to the difference between air temps and leaf temps.
