(aquarium plants.com substrate) help!!!

Just the Turface. I am using a scattering of peat moss underneath, and soaking it with fertilizers and mulm to "charge" it up with nutrients. The Turface is very absorptive and will hold on to certain nutrients until the plant's root need it.

You could certainly put gravel over top, but the gravel or sand, etc. are heavier than the Turface and will eventually sink to the bottom anyway. Plus, I like the look of the Turface Grey.
