I was wondering if there're any solutions for an inexpensive substrate for my 100. I'm looking to create a substrate about 2.5" in depth.
Now, I've read the posts about Onyx, Fluorite, and Eco-Complete. I really, really would like use Eco-Complete, but I just can't afford the twent-some dollars that it costs per bag. My budget is around $40 for the substrate, does anyone have a suggestion about how to create a viable substrate with only $40 in the pocket? Thanks in advance.
