I read your previous reply, this chart is a better example but for full cycle not just flower although it still fails to appreciate low humidity growers.
What is my vpd when I hit 32c and 30percent humidity? This is a common situation for agriculture in warm climates.
Tomatoes and cucumbers come from different environments but I've seen tomato at 30c in low humidity produce great crops species specific strains.
What you learnt dosent cut it with a lot of situations, I didn't ask for the average I asked for specific warm weather plants that yeild well in those climates.

The humidity in Afghanistan tomorrow at mid day in 34c temps is 12percent.
But where the best sativa comes from in Kerala it's 30c and 70percent humidity.

Edelweiss grows on top of the Alps.
Let's grow roses there too, and tulips. They will do great.
You did not come up with a link, @Tetrahedral , and all your other examples are anecdotical.
So a serious conversation with you is impossible.
Too bad.
You are a fine example of the bro science community. People have to trust you, because you say so.
But backing up your stories with a link to a scientific paper (which was easy to find, you said).... nope.

What do you yield under what light on what surface?

Absolutely horrible advice. As @Keesje stated there is no way you would want your plants to be growing in 30% Relative Humidity.. Even at 75 F - 35% RH you're looking at a VPD of 1.94 which is horrible..
I'm from Michigan so that said we have lots of humidity most of the time, especially when growing in basements new or old. I have had the absolute best success keeping the rooms (lights on) 75-55% and lights out 70-50%...
It is also very strain specific as well.. Honestly some strains I've grown hate the lower humidity and were used to growing in greenhouse environments with 60-65% humidity but I'm not going to run those numbers in a basement with wood, insulation etc..

The best growing locations in California have around 30% humidity, look at the gold country where most of California weed comes from... 25% humidity today.

That isn't the Average humidity though.

"What is the optimal range for temperatures and humidity?"
20-30% Humidity isn't Optimal by any standard except yours. Find me any professional or experienced grower recommending it. Also no one asked about what is the optimal outdoor humidity he asked what the optimal Relative Humidity in his ROOM was. I'm happy you have good luck outdoors and in California, you're off topic and giving bad information.
