I can't find it now, but I saw a video where a guy was trying to offset just the CO2 he produced himself with plants.

   1. He gave up on "plants" because they were nowhere close to offsetting him.
   2. Switching to algae, he used a 55 gallon drum of it because the numbers said that would work. He gave up when the CO2 level reached something like 2000 ppm
   3. He ended up with something like 3 drums, as well as special mixers to make sure the algae got access to as much CO2 as possible, and he had lights focused on the algae drums to make them as efficient as possible, and he still ended up barely keeping the CO2 at the "dangerous but not completely toxic" level, and it wasn't stable either.

Plants are a terrible way to try to manage CO2.
