,.. if i switch i will get the pens to help regarding € initially and get by with them and then in the future upgrade, like you going no run off to adapt to your specific conditions i think i need to do it the same regarding the pens.
I think that the pens will be fine as long as they are accurate.
They will take more time and effort though.
My PH pen takes about 3 minutes to stabilize the reading. It adds up when you do a dozen readings a day.
Yeah i know vpd plays a role,..
I personally don't think it plays that big a role except for the risk of mold above about 65%.
I am growing two plants with the RH between 30% and 45%.
I seem to end up with thick dense buds,..
