Yup that's a 20 cu ft one that Exit recommends.

I'm doubling the size to be extra sure I don't run out of gas.

I don't blame you. Seems like the bigger the better.

I'll just ask the question: any pactial way to get a bigger volume ? Buy more tanks ? I've been exploring this method, and my ideal would be the 'hypoxic room'.

Buying more tanks becomes complex because you then need to construct a "cascade" system to equalize their pressures and flow rates. You're much better off just getting a larger tank.

A "hypoxic room" is very difficult to construct outside of a laboratory or industrial setting. Creating a sealed space of any size, and then providing adequate gas to first flush out the air and then maintain a CO2-free atmosphere, is beyond most of our capabilities.

The one thing you might explore if you want to pursue large-space inert gas hypoxia --and you would be on the cutting edge for this-- would be the use of liquid N2. That is a much more concentrated form of N2 than compressed gas, and you might be able to use it to purge a large space of air within a reasonable amount of time. You'd need to balance the hypoxia against hypothermia, however.

Liquid N2 is available at industrial gas suppliers like AirGas --veterinarians use it for cryo storage of semen; some women attempting to get pregnant via donated sperm use a dewar flask with liquid N2 to keep their doses frozen-- and I don't think you need a license to get it.

I can make guesses at how to go about applying liquid N2 to ctb, but I have no certain knowledge.

@TiredHorse , well only if some people got together and made it happen ...

http://shop.gase-dopp.de/Stickstoff-28-2-Liter-Flasche-neu-gefuellt for the EU it's at 200 bar, likely not liquid ? Still high pressure. I get the impression that you'd need to bu from forms that supply to industry.
