And my VPD has been on point since starting. Just no sprouting yet. It has only been about 40 hours and I had mm size taproots coming out when putting in the 1” hole.
Your controller picture showed 1.09 VPD, that's why I said don't get to wrapped up in VPD.
VPD is kind of new, Growers have been relying on temp and humidity much longer.
As long as your equipment isn't turning on and off constantly and ramping way up and down trying to control it then definitely go for it.
What max setting do you recommend for the fans? And I need to look into the sunrise and sunset more before adjusting so I better understand. Right now the cycle has been working as needed.
I use intake fans so my intakes will adjust with my exhausts so I'll never have a situation where my air coming in isn't enough.
With passive intake, it depends on how many flaps you have open at the bottom of the tent.
You could slowly turn up your fan until the walls are at a point that you wouldn't want it to stretch anymore and keep that as your max. I would say nothing over probably 5 or 6.
My fans always run at a minimum level of 2, I like to constantly exchange air. They only go higher when triggered by Auto Mode but will never drop lower then 2.
My humidifiers I keep at 6 max.
I'll explain sunrise/Sunset.
As you see from my last post picture, my lights are at 60% from 7am to 7pm with a 30 minute sunrise sunset.
At 7am my light will come on at level 1 and ramp up 1 level every 5 minutes until at 60%.
At 6:30 pm it will drop 1 level every 5 minutes until off at 7pm
Light power divided by how many minutes you want to ramp equals the Sunrise/Sunset duration setting.
For me
Light 60%
Divided by 5 minutes interval
Equals 30 minutes duration setting.
Idk if it does anything for my plants but I believe slowly adding power to the light over time will put less stress on the light and make it last longer.
