Re: [APD] Re: DIY CO2 in terrariums?
If we're taling about CO2 in the air, as opposed to in the
water, the amount of CO2 that's normally in the air is
roughly 200-400 ppm, isn't it? I'd think you'd need a lot
of added CO2 to make a dent in that.
Aquaria water, otoh, has just a few ppm unless one adds CO2
-- no wonder terrestrial plants are so shy under water.
