If you are in seedling stage and veg 80+
And if you are in flowering stage 50%-

Set humidifier to desired humidity (for example 60%), then lookup temp on VPD chart and hit that target by controlling exhaust fan, raising/lowering lights, heating/cooling space, etc.

Then adjust lights via rheostat for proper DLI.
