It's true that substrate is sometimes treated like dirt. I
put it down last on the priorities of where to spend
limnited dollars. You can get by with spending the least
on substrate. Cheaps lights or a lack of l;ights can be a
headache but any convenient inert sand or gravel and some
amendmemts can serve you well without costing a lot.
I also assumed one wanted to grow in a fast grow tank. You
could opt for a slow grow tank and use less lights but
still add CO2.
You could go for and even slower grow tank and skip the CO2
and grow a la Walstad or one of the ways that Roger Miller
BTW, as I recall, Walstad suggests getting some dirt from
the backyard to use under the gravel. That won't cost
You can spend a lot on substrate, but if you're
prioritizing your dollars, I'd suggest moving that one down
to the bottom.
Anyhow, that was my reason for saying so.
