[APD] Re: dirt, moderate CO2, and moderate light
RM: "Please don't use the subject of posts to Diana's forum at AB as an
indicator of problems with her method. Sites like AquaBotanic exist mostly
to help people with problems, so the posts are about problems."
RM: "Judging from the content of letters here one might wonder why anyone
tries to grow plants in aquariums."
Heh, no kidding.
TW: "I was just commenting that Walstad's method isn't as carefree as it
might seem because the definition of 'dirt' is not there yet."
RM: "I'll agree that soil-based tanks are not entirely care-free. I'm not
sure that the definition of "dirt" has much to do with it. Commerical
substrates available these days are pretty variable, and I don't see that
variations in dirt cause many more problems than variations between
different sorts of commercial products."
See the discussion about the 'power' in Amano's Power Sand. I think the
jury is still way out on the optimal substrate.
RM: "Besides, Diana does encourage people to use potting soil. That
narrows the definition of 'dirt' pretty substantially."
Don't think so, but that's why there's the discussion to begin with.
