Up dating my room, could Use some insite.

Ok so im in between grows right now, i have some clones well rooted with a good veg room. I wanna update my system to harvest every month once started. I have room for 4 blooming plants kinda tight. My plan was to have 1 plant per 5g-bucket, 2 buckets on 0-4 weeks blooming and 2 buckets on 5-8 weeks blooming. I think ill have around 55,000-58,000 lumens in the room, with a yeast C02 set up. (Question: Does the yeast C02 idea work? and would it help yield until i can buy a C02 system[8months]). So with this set up and proper care could i possibly get an Oz per plant, so 2Oz every month?
Thanks

It sounds do-able, although you should expect that it will take a little time to get things all stable and nailed down, so it may be a few cycles before you reliably pull an ounce per plant (depending upon the strain and the space, etc.) I always get a little less than I expect in a new space, leading to tinkering and modest improvements.

Does the Yeast CO2 Idea work well enough to increase yield?
