Does CO2 speed up flowering?

This is my 3rd grow. 1st with CO2. 1200-2200 "depending on if hot water heater is running".
Average temp 88
10 hour light schedule.

My question is this.

This is a 9-10 week plant. The pictures above is only 31 days from the switch. They look like they are only few weeks away at most, but that puts them at 7-8 weeks at most instead of 9-10. Does CO2 contribute to faster finishing times?

Current strain is sour lemon haze.

those are a long way from finishing. and a hot water heater puts out carbon monoxide, which can kill you. and no, c02 does not speed up finishing

I will take some better pictures tomorrow. The hairs are turning brown I get a new scope till August so I am a bit curious.

As for the gas heater. CO is a very low by product of natural gas. It's majority of by product of N.G is CO2 & water. But I also don't recommend people using that technique unless they have adaquate monitors in place through out their house
