Hi Marshall, I once got the permeability figures from a resin site, but did not know how to apply them.
What do you think the effect of N and O and CO2 will have on the sol?

That is the only "problem" I know about it. I posted the actual numbers here earlier, but seem to be unable to find them again right now.
