Closed Exhaust system in Martha using Rebreather?
    #5445524 - 03/26/06 10:31 PM (17 years, 10 months ago)

I am currently constructing an airtight martha I've gone with the design of a coolmist (w/ filter over air intake) for FAE in the top and two smaller holes in the bottom with polyfill tyvek for pressurized exhaust (to fight c02 buildup) I am still trying to find a better solution than two holes or a exhaust fan in the bottom but I was wondering if you could somehow filter the c02 and just use recycled air using a rebreather (used in diving) I am by no means an expert but my understanding is that your FC needs FAE so that there isnt' C02 buildup and the little guys can get oxygen as well, but if you can completely eliminate c02 with a closed exhaust system then wouldn't that work?

the following is a link to a guy who designed a ghetto rebreather:

some feedback from someone who knows a little about gas exchange in a fruiting chamber would be nice

EDIT: Was stoned and pasted the wrong link

this is a very interesting topic. i am just about to build my own martha and i was wonder if i should just put some tyvek holes in for pressurized C02 exhale or if there was anything else available. i'd love to see some type of rebreather designed. sorry i couldn't help :P

Maybe I read that thread too fast, but I didn't see anything about a rebreather in there. The whole thread was about G2G transfers. Your idea sounds like it could work. My question is why would you want it completely sealed in this manner? As long as the air/water pumping into the martha is clean, you shouldn't have any contaminant issues if this is your concern.

"My question is why would you want it completely sealed in this manner? As long as the air/water pumping into the martha is clean, you shouldn't have any contaminant issues if this is your concern. "

I don't want the enviroment inside my Martha to ever have contact with the enviroment outside or the enviroment outside to ever have any possibility of contact with inside the martha. Theres more than just shrooms in my grow room and with air tight martha's it's easier to deal with different climates and scent control. It took me like 4 days to figure out a way to cover the stitching on the front of the martha next to the zipper while still being able to open it.
