Re: On Beer Gas

That's fine, but beside the point. Rachel's original question was could this
stuff provide her plants with a source of N, negating the need to dose KNO3
separately. It can't. We don't aim for a creamy head of foam in our planted
tanks.
On the other hand, during the heat and humidity wave we experienced here in
Toronto this summer, I did appreciate lots of foam in my beer...
