Vapor Pressure Deficit - The Hidden Force on your Plants

Forunately in my neck of the woods, when ambient outdoor temps rise, so does the humidity so no real attention to this factor is needed until winter. The air gets very dry with decreased temps in winter so I augment day time blooming with a vaporizer in my ‘lung room’. Increasing RH to 40-50% during winter helps to eliminate PM as well, which loves 20-30% in a cooler room. I would never run a room higher than 60% RH regardless of temps as that is just asking for trouble, IMO. thanks for the article, good work crazyben!!
