Hello! 2 quick questions?

Hello my friends. Happy Monday. So I did 2 little tweaks in my tent. Since both my autos are now flowering, I...
a) Adjusted the light to 20/4 from 24/0.
b) I've read today that "When a leaf absorbs IR, it heats the leaf creating actual leaf temperatures of 5-7 degrees higher than the 78F degree air temperature. Thus with light sources rich in IR, an air temp of 78F is functionally 83F-85F to the plants metabolism. LED’s emit no/littlr IR, so to achieve similar metabolic rates found in HID or greenhouse conditions at 78F air temp,LED growers need to run the room air temp at 83F-85F."
So, because I have my growtent next to my bed (not recommended) and the fans don't let me sleep, I had no fans but had my tent open for optimal temps. It's winter now and temps are 22-24°C. I closed 3/4 of the growtent "door" for better reflection and to raise the temps a little bit. Temps inside the tent are now 27-29°C. Is that too much? Light is 240w Meijiu QB at 20inches(50cm) distance. Thank you guys.

No, those temps with LED should be perfectly fine. I would not let it get any higher but should be fine where it is now.

Could I have 2 more mins of your time? Since my temps are little higher now, would you add Co2 if you were in my shoes? I've heard that Co2 can be used in high temps or when you have too much light (above 1000ppf or something like that). One of my friends has a "Smart Co2 bag". It's like 12euros so maybe It doesn't do shit. It's first one on this site: https://www.theco2bag.com/

Also, 29°C was an exaggeration. I assumed it would go up to 29 but it's been 26.5°C for a day now lol. Thank you for your time.

Waste of money...

No worries. I would not add Co2, from what I have read those bags are pretty much garbage. Most people I speak to say the only way to get Co2 working right is to add a tank, regulator etc. plus have a sealed area. I would just skip that idea if it were me.

For CO2 you need to run sealed room...
 
Hey, sorry to bother you again. Light has been off for 2 hours now(it's almost 3am) and the temp was 18.8°C (around 64-65F). Is that too low? If it's too low I'll change it back to 24/0 and the temps will be around 26°C so I guess it's not a huge problem.
 
You breath out co2 all night long. No need to add it. 64f is fine for lights off. If your comfortable, your plants are comfortable. Thats kind of the golden rule.
