Grow temp/humidity day/night...
Sciolistic_Steveanswered grow question 2 years ago
check out a VPD chart that shows suggest ranges for various stages of life cycle.
RH % is a little high. >65 puts you in territory that grows microbes too effciently. raises risks, but with 80-84F, the VPD is looks good when lights are on. not sure what it significantly impacts in dark cycle... Defintely don't want RH going higher. Preferably drop a bit and if so temps scaled down slightly too. A little higher VPD than rpesently is fine, if not.

Is It Safe to Direct Humidifier Mist Above Grow Light in Tent Setup?I want to place my AC Infinity humidifier outside my grow tent and direct the mist through a pipe into the top of the tent, as shown in this diagram. However, my SF1000 EVO light will hang directly below the mist output. Could this cause issues?
