That could be a reality for many growers in the winter yeah?unless the RH is simply too low to allow the stomata to fully open.
I think Doc and Duggan would agree that 10 mins or 1 hour makes little difference. The science says that at a certain Temp and rH you can force the stomata open. It’s the basis behind vapor pressure deficit.
Knowing that, and knowing my HpS takes a little while to warm up, I’m okay waiting an hour to spray. That helps me make sure that my ‘lights on’ temp has been achieved and if my humidity is being controlled properly, stomata should be open.
While we’re on the subject, the last time I sprayed Brix I hit the tops of the leaves in addition to the bottoms and it seems to have scorched a few leaves. That or it’s dried on the leaves or something. It looks as though those fans are damaged. I’ll see if I can get a pic. It only happened on Durban.
