if cost is an issue, why not get a nutrient base and lay 2" thick layer of gravel above it?
I was leaning toward the Eco because I was led to believe it is better than the Fluorite. I am concerned about the black ECO mixing in with the gravel but was told that since its finner it will stay down.The advantage of Eco-Complete and Flourite is that they are specifically formulated with the minerals that plants need. The cheap alternatives like Oil-Dri and cat litter and such are just fired clay. Yes, they'll work, but not as well. I'd say you'd be better using a base of EC topped by gravel.
But if you're going to top it with red flint, might I suggest you go with Flourite or Flourite red instead of EC? EC is black and it would not look good when it comes up through your reddish gravel. Flourite would look more like the flint, and as a bonus, at least around here, it's usually cheaper too.
Well I bit he bullet and went with fluorite. I plan to do the first 1.5" with this and the next 1.5" with regular gravel.As said above I would check out soilmaster select if I were your. A lot cheaper and will serve as well.
For what its worth eco is easier to plant in than flourite.
Good luck

I plan on using the old stuff on top of the flourite.10 year old gravel substrate? Full of mulm and all that other good stuff.
I'd have kept that original "juicy" substrate.
