I'm running a co2 gen and co2 tanks. My room temp is at 88 and directly under the lights its 95 the ppm of co2 is from 1400-1500. Air cooled hoods. I would like answers from.growers with experience in this or similar situation

hmmm you should have a fan directly at the top of your plant if you want to stay safe with those temps. at 90+ you could very well get some nute burn if you feed with anything over 1/2 strength every other watering. (900-1500ppm is best, anything more or anything less will result in small leaves with short growth.

Yes I have plenty of air movement directly hitting the plants, Nute burn related to heat issues?

No of course not that's crazy. A small cheap AC. You need to get the temps down a bit. You can go a little higher with temps with CO2 enrichment. Something I never knew when I first started.

What to is ideal?? I mean the plants look great just dry out a lot faster. When I said air movment I ment I have 4 circulating fans constantly blowing on the crop. I was told to measure the air directly above the hood for temp results and not in direct light from the how bcause it.will read higher than actually

well ive been doing research and ive seen alot of growers peaking at 95, and when i said 95 in my room i ment that my thermometer is alot higher than it should be because radiant heat from the lights... when not in direct light from the hood it is 85-88... i think everything should be okay in my room, besides having to water more frequently

Yea I mean if they look good it's all goo. If it's not broke don't fix it!
i figured, ill give it a few more days, but when i think about it, obviously not the foot candles, but it really does replicate a nice outdoor setup, high co2, high temps, high winds. we shall see! would still love some info from experienced growers that have this issue and how it was resolved.
