A common VPD misconception

I just jump into Vpd and I get a pulse pro and a pulse one

Yep, without factoring in leaf temp, VPD is only two thirds of an equation. Gotta gotta gotta measure leaf temp.

in my case leaf temp is minus 2 CĀ° of the actual temp and you can set it into the pulse app

That thing is fancy! Jumped back a bit when I saw the $ tag but I guess good sensors arenā€™t cheap! Do you like it?

Well I am really happy
I have it like a week and what I ve learned so far:
-when my lights are on I must keep open the doors of the my grow room to raise my vpd to 1.5
-i do watering only when my vpd is 1.5 and plants are loving it
-plants are really releasing co2 at night
-I donā€™t need to use my fc6500 evo at 100% because at 80% I am at 52 dliā€¦ to bad that I donā€™t have co2 to take it to the moon ( my next goal)

if vpd is maintained, how much variation in outcome is due to where in the scale (i.e. which temp.) things are?
