Probably not, it depends on the leaf surface temperatures. What I look for is the Leaf VDP, I was not clear about that before sorry

The room temperature and the relative humidity tell you the room VDP. The room VDP and the leaf surface temperature give you the Leaf VDP. This ling has a calculator that.

    • Assuming your leaf surface temps are 5° below the room temps I would have to say hell no to those numbers. That puts you in a negative leaf VDP and that should be positive.
