Plants seem to droop slowly over the day , what temp should I run the air and leaf temp? Vpd chart seems really high humidity, if I run 80 temp and leaf temp at 79 my vpd is 1.29 is this correct?
I used to grow with hps for 10 years ,but the led and temps are throwing me off ,can anyone tell me temps and humidity and leaf temp approx should be for leds ? WRX

80-82F leaf surface temp. Many growers will run up-to 85F canopy temp.
Which VPD chart are you looking at? There are so many out there. I believe Pulse VPD charts are what most people use: https://pulsegrow.com/blogs/learn/vpd-charts-in-fahrenheit-and-celsius-with-leaf-temperature So according to that... Seedlings/Clones - at 80-82F -> humidity ~68-80%
Veg - at 80-82F -> humidity ~60-72%
Flower - at 80-82F -> humidity ~50-64%
