Pro co2 buckets?

anyone heard of and used pro co2 buckets?
I’m building a 4x4 grow tent, using a spyder farmer sf4000
and oversized ac infinity t8 and wanted to use co2 and I have seen these co2 buckets and was wondering how I can incorporate this into my tents atmosphere?
experienced growers know co2 can double your plants uptake mixed with the right amount of light.
Does anyone have experience with the product pro co2?
