I will mess with vpd when everything else is perfect and then still prioritize the temp/humidity measurements over the VPD
Mine does too I have a controller 69 wifiMy controllers calculate VPD. I look at it about as much as I look at temp and humidity.
I let VPD rise throughout a grow. The plants like a higher VPD as they get older.
For me, I notice that they just grow faster if I have it dialed in. I'm still new, but having my humidifiers set off vpd has helped me stay ahead of the temp changes with lights on/off.I like the answers, mine is always high. I haven't had different results dialing it in personally. If it was different it was negligible, I tried a few times. Maybe I'll give it another shot next grow. What are the biggest things you guys notice with dialed in vpd?
