Sir,
Bleaching destroys vegetable matter which in turn halts chlorophyll. would not advise.
its not that easy co2 can kill you i get dizzy at 900ppm,
1200-1500 max needed in a super grow room.
on the average in my city ppm co2 is abbot 364-465ppm.
in my flow through design i run 600-900 ppm.

BE SAFE
