The point of vpd is the control of the perspiration right ? Expand the formula and you'll see there are assumptions built into the model for atmospheric pressure - full control means understanding that then building your own chart imo (I'm not there yet lol, just saying hello 🤷‍♂️👋🏻)

@CRiSPrGrow, I'm not 100% what the typical procedure is but i found a site that was saying you need to know the air temperature, leaf temperature (using a temp gun), and relative humidity. and then you can plug those into the formula(s) to get the VPD. you could use a magnifying glass to check the pores but I'm just going by what the RH is and trying to keep it around 55%-65% so i know it's not too dry. Pores close to retain water when it's dry out and they cant properly cool themselves which could slow growth (at least from what i've read haha). Cheers!

I know how it is to have powder mildew during harvest and it's unfortunate for sure but if you mix tap water, a dash of baking soda and a tiny hydrogen peroxide together you can spray them as needed whenever you notice something and wipe it off the leaf or spot with a cloth. Also at harvest you can always give your buds a wash

@CannaCanuck420, it is a very unfortunate time to be having any issues, especially like that. Not What I planned on at all haha. I really appreciate the Info! I did a big spray with water and baking soda and that really seemed to help. Haven’t seen anything coming back yet so fingers crossed that continuing to spray will help keep it away.
