Proper temperatures in LED grow

No.1 went up to 30 an hour before lights out. LST was 2-3° cooler, should I decrease the temps a bit as the 3rd week just concluded or is 30 fine? Boards are on 180 and 200 (slightly different hanging height), lux is 55-60K.

This might sound crazy but...

I was running mine at 90*F (32*C) for the last week. Responded well. No signs of heat stress. Growth rates seemed to improve.

I'm pumping it up to 93*F today. The lights turn on in 4 hours... I'll be able to see how she responds to the increased temps a little while after that.

Running fem white rhino (classic indica… short, tight internodes, wide leaves). Loosely following VPD, so my RH is pretty high (70%+). In mid veg.

The vpd calculator is quite handy:

It allows you to calculate proper temp and RH, this one also allows you to adjust to leaf temprature (being lower for leds than HPS). Id use -1 for your lighting and +2-3 for hps. Remember that its more a guideline than a bible, something to use to dial in which direction to take your enviroment rather than absolutes.
