HELP! Need help with CO2 room temps

Hello Rollitup. Long time grower, new member. I need help. i am running CO2 at 1500ppm and 82 degrees for veg. i am about to go into bud. usually I drop the temp a little for bud, but I know to get the full effect of my CO2 i have to run a higher temp. So my question is, if I am at 82 degrees and getting good results in veg, what temp should I start bud at? Do i drop it a couple degrees, like I do without CO2? I don't want even the smallest amount of heat stress during bud? Please help????

Brst you can do is read your plants leaves and fine tune it . Not preying too cold, taco shells too warm .Total newbie but I aim for 1200ppm and found most plants(strains) crave the heat 85+ first month 80-82 next 2-4 weeks last 14-10 days i flush while dropping co2 and temp .
I grow for my house hold and had co2 bottles and regulator before growing equipment.

1st run I did 1500ppm found it too much to handle... I'm not hand watering anything more than 1x daily.

I used to run it at 1200 for 5 weeks and taper down 300 every following week successfully.

Some people run it to the end and swear by it, some people actually even rock 65f at 1500ppm and swear by it, so you might get different answers here.

Fwiw, use leaf surface temp instead of ambient that way you know where your optimal photosynthesis rate will be.

Keeping the root zone cooler than the foliage will help prevent stress ect.

Match CO2 PPM to your feeding PPM, matching 1000 ppm to 75F, 1200 ppm for 80 up to around 1500 at 95F. Don’t go any hotter or richer in CO2 than 95F@1500 ppm as negative problems can arise.
