Hey I have a question for my vpd gurus out there.
@Mañ'O'Green @pop22 @Waira off the top of my head
while I understand vpd as it relates to water movement though the plant, and thus the movement of nutrients.
incant seem to see to much out there on how cO2 relates to vpd
What I’ve come to understand is that higher vpd equals more fluid movement. Then cO2 just helps the photosynthetic process.
It all ramps everything up, so my question is this. Are my thresholds going to be higher on the vpd charts due to my high cO2.
So if the vpd chart says veg should be at a 1.1 kPa that’s assuming normal cO2 levels. If I have elevatede cO2 wouldn’t it stand to reason that number would be higher?
