i'm curious about substrates
beaslbob suggests pure peat moss (with a cap)
walstad has organic potting soil
there is remineralized top soil
(i've seen another from a different forum that started with humus & with a bunch of additional minerals added - greensand, azomite, laterite, being a few)
trying to go for simple, i'm sure walstad is hard to beat
i'm looking at my one tank at home and thinking "damn i hate nutrient deficiencies!"
what 'simple' ideas do people have that could pose a substrate that would be complete for plants ?
walstad is simple
MTS is ... almost simple
peat moss, makes sense, it's got all the nutrients that made the moss right there, where could any deficiency or toxicity be ...
any ideas others may have ?
