Sir I tend to ignore VPD or humidity as it were.. There is a whole lot of stuff that happens with proper watering.. And it's not even that complex it's more to do with saturation vs. intake and transpiration. My plants gobble up as much as 4 litres of water a day. when I had crazy high temps this past summer I still didn't bring the old humidifier out, I was adding more water :).. It's funny how much people get wrapped in the idea that there is this perfect temperature humidity zone.. I mean there is but at the same time lots of plants grow out of that perfect zone with zero problems.. Would you believe 95% of the mistakes I see on this website as caused by the growers themselves :). It's so easy to be like bad soil, bad lights, bad nutrients... What's a lot harder to do for us as growers to do is ask where in the hell did I go grow wrong? ha ha ha :). Anyway you learn the most by growing and trying new things so keep on growing and pushing for bigger better plants.
