also i read an article by nasa, talking about the effects of growing plants under elevated light levels. there came a point where, regardless of co2, temp, RH, etc... the plant needed more calcium to fuel photosynthesis than could be fed to the plant, even with foliar applications. fluence makes a high ppfd grow guide, and it has good info on co2 enrichment, and the point of diminishing returns. it's tailored to their spyderx led light, but the info should still be a good read.

Optimal temp is kind of relative and depends on how much light and CO2 but yes you will reach a saturation point once all the factors are met and the plant cannot move any faster.

Best temps for consistent co2 enriched gardens (900 - 1500 ppm at all times during lights on photoperiod) indoors under HID lamps is 82 - 86 degrees fahrenheit at plant canopy level....provided relative humidity. This is just a general guide.....it is very much cultivar dependent.
Are my temps too low for my co2 and rh levels?

For my liking they are. I would raise temp or lower humidity. What lights you running?
Ok I agree, will do.

I just seen so much weird high temps and rh while ppl running co2 . I am supplying two rooms via 3/16" Y connector and one T split. Room 1 co2 levels run same due to cfm exhausting from smaller cu ft room 2 via one 6" AC and one 4" AC to larger cu ft room 1 which has just one 6" AC exhausting to room 2

Room 1 temps are 70 to 78F and RH 55% to 60% running two 1k watt hids with solistek mh bulbs and 10 150w recessed full spec/IR leds, and two vert hanging two bulb T5 florescent led veg

Room 2 temps 72 F to 79F but i have to keep RH 65% to 70% in rm 2 which exhaust hot humid air through AC infinity to room 1 so in order for room 1 to stay 55% to 60% rh.
I'm running 315w cmh phantoms, x2 4100k hi lux and x1 4200k Phillips bulbs.

Room 3 off of room 2 temps are 74 F to 81F RH 66 to 71%
Running
X2 leds Viparspectra 250w at 70% And x1 315cmh 4200k

This is so 8nteresting bc in my rm 3 size 5 x 5 x 8 running same strain, same med, same nutes, ro water, very bad calimag def, while running co2, 75 to 80 F, rh 65% to 70%20210228_160146.jpg
