Automating CO2 exchange
    #1631540 - 06/13/03 04:41 PM (14 years, 1 month ago)

My cousin has a terr. setup using perlite for humidity. He wants to automate CO2 exchange. He has read about using a aquarium bubbler. Has anyone tried this? Are there any better ways to set up the exchange?

Thanks

i don't see how a bubbler is going to remove CO2 from your terrarium very well. this pushes air into it and unless you have holes down near the bottom CO2 won't be pushed up and out (CO2 is heavier than regular air).

however, if you have a raised platform in your terrarium and an air pump placed at the bottom going OUT you could do it. layers, from bottom to top: perlite+water (optional), pump, couple of inches of air, platform, cakes/casings, space for shrooms to grow and what not, top wth filtered holes. watch out for the heat generated by the pump. i guess you could keep that outside if your pump allows you to connect an intake tube that you could run out.

do a search for the "poor-mans pod" thread and all your questions shall be answered, but i'll tell u the basics of it here.

its not co2 exchange you should be worried about, rather air exchange-- its the process called air entrainment: if the pump can provide 2-3 air exchanges per hour, the fresh air and co2 will MIX together, 'reprocessing' the old air and preventing co2 from building up.

if you are using a regular sterlite/rubbermaid container right-end-up, the lid is loose enough to release excess air so pressure doesn't build up.
