Need A New Fan What Do You Have?

The way I read it your environment calculates vpd but I dont know for sure

Well VPD determines where I set my environment controls and the environment determines what my VPD is... Life is all a circle....

I am no good at explaining but it's pretty easy though once you start messing with it you really see the short falls in your room and your equipment etc.

That was a good read . I think to simplify it in flower rh should be 60 percent at 80 degrees for transpiration.

Hey Sarge.
Where did you get those numbers from ?
Is there a chart somewhere ?
I thought RH should be around 50% Or less in flower ??

You Need To Know:

Leaf Temp
Ambient Temp
RH

Without leaf temperature saying you need this temp with this humidity may work but isnt quite all there is to it...
