Would plants stop consuming co2 during a simulated moonlight night mode lighting?

i have the finnex planted plus 24/7 which i also have connected to a timer so it turns on at like 9am but i was wondering about how long because the lights start to simulate the moon with dim whites and blues around 8pm or earlier. so if i found out if they stop consuming co2 whith a certain light setting. i can conserve more of my co2. I use the fluval co2 45g cartridges and those are like 15 bucks a pop. ive looked online for better solutions but im not the best at DIY. hense the kit.

Edit: i just realized i can just use a PAR scale to make this deciscion >< well sort of par starts to rise about 4:30am from 0 to 100 at noon and then decline to 0 at midnight(according to this person's readings)

from my light to my substrate its about 17.5". i cant really figure out this guys code: offset depth thing

 

You're really, really overthinking it. Just keep your CO2 on a timer for the duration of your lighting period. If there's no light, plants won't photosynthesize. Photons are photons regardless of wavelength or intensity.

I keep mine on for 7 hours a day. If you don't want to swing the 45g cartridges, invest in at least a 2.5 pound CO2 canister (5lb or 10lb would be even better) and get it filled at a welding shop, beverage supply store, fire safety store, or gas company.

yeah i would like to as it seems to be the way cheeper method, but regulator vs tank thread matching plus solenoid for timing. thinking about it hurts my brain. im simple

Most regulators use the standard threading on the tanks, unless you intend to use the one for your little Fluval cartridges... good luck on that, you'd have to play around with some adapters and probably DIY. It's better to just invest in a regulator with a built-in solenoid that fits standard sized tanks.

It will be much cheaper in the long run than constantly replacing disposable bottles.

oh no lol. i want to stop using the fluval kit if i can... however i did buy an in line solenoid for it. that hopefully will help for now. do you have any co2 tubing you recommend getting? i keep seeing ones that have 40 psi and what not tagged on to them. the only thing i know about psi how empty my cartridge is. hopefully the inline solenoid works fine in the meantime
