So I understand with LEDs you can get a higher temp thus getting a higher humidity and getting a better VPD,is 85 with 70% too high temp and humidity? They look like they are thriving.
If the amount of water vapor in the air stays the same high temperatures cause the relative humidity to drop. Lowering the temperature will raise the relative humidity. Keep in mind that in both cases there may be the same amount of water vapor in the air. The only difference is how much water vapor the air "CAN" hold.
