Unless you can seal the grow room and circulate it I would say it's overkill for 2-4 plants. It will definitely make a difference in plant growth if done properly. This is done alot in the commercial side of cannabis industry. Don't fall for the cheap Amazon plastic bottle crap you will be disappointed. Get a real CO2 system and see the difference. It also a little dangerous, lol. PAZ

CO² is essential!
But there is enough in the air to keep your plants more than happy. You need it at the roots too.
That's a good light. Focus on maintaining an ideal environment. If your environment is ideal you will get most benefit.
Using elevated CO² levels requires higher temps and more light than what you have to get benefits so overall the cost is not just the CO² bottles for little benefit....some quote 20% higher yields but 5 to 10% is probably more accurate .
I have all the gear and a sealed room with climate control but don't use it as its not worth it and my yields are quite high without it.

That’s something used more at the commercial level where yield is the number one goal. I see no benefit at the recreational level
