To add Co2 or not to add that is the ?

I have 3 rooms that I pump co2 into. I have it set at max level in room one and exhaust room 1 into room 2 and exhaust room 2 into room 3....I keep the controllers and ppm counter in the last room and that is where I get my 1200-1500 ppm reading. The only reason I do it this way with to spread the gas throughout all 3 rooms....works very well actually and keeps the heat down in my 2 other rooms. the unit I run is a hydrogen water cooled LP burner. That part of it is a whole crazy other set up :smokin:

What is light bleaching?
Does anyone have a picture of it?

co2 is only worth your time if everything is in check

edit: never mind I googled it. That sucks. Does that come from heat or too much light?

That comes directly from too much light, too much power so to speak 'burning out' the capacitors (chlorophyll.)
