First of all, gravel can equal substrate. Substrate is simply a nutritional source and what you anchor your plants into. I'm using regular gravel in a few planted tanks with great success. It allows good flow through the roots while still providing an easy anchor for plants.
The only problem, as I see it, with ordinary fine gravel is that it is inert and will provide no nutrient storage capacity. You could supplement your gravel with Laterite, Flourite, Shultz Aquatic Soil (from Lowe's) or Root Tabs. What color is your gravel? That's going to dictate, to a great extent, what substrate enhancer you might want to mix in.
