can't always have 55% RH and 17c / 62f for drying.
those values would be .55 on the VPD chart
curious if you could cross reference if your temps and RH were different and still have .55 if that would be ok for drying?
this shit just pops randomly into my brain BTW
thoughts?

You don't want a variable microclimate, try and keep it consistent between 55-60% RH and temps low between 60-65. If you're in that range you're getting a head start because it's already curing while it's drying. The lower temps will help preserve your more volatile terps like pinene.

Love the thinking but it doesn't work. Let's say your drying area is 75°, you need 80% humidity for .55 vpd. No bueno.

Discussion: Vapor Pressure Deficit/Differential (VPD) during drying & curing

Considering how effective VPD obbservation and managment is proving to be during growth, I can only presume it will prove to be as effective during drying & curing (once optimal ranges are established). Why? Because Vapor Pressure Deficit/Differential is the measurement of how saturated with...

I'm being lazy and not reading, but where this makes sense is if you don't have full control of your environment. If you can't directly control the relative humidity, you change the temperature to manipulate the RH through VPD. If it's too dry, drop your temperature and rh goes up. But if it's too humid and already warm, you don't want to push a higher temperature because of what you're going to lose, but hey... you might not have a choice. I keep saying I'm going to do a mini fridge conversion... SOMEDAY
