Here's a link of how to set up a natural planted tank. I just use cheap top soil sold at walmart or lowe's. Cover that with a layer of gravel or sand. Works great for me, and not as expensive as the flourite.

This says you don't have to use a filter, but I still do, just in case. I also don't follow the "one water change every 6 months" thing either...sounds terribly bad for "old tank syndrome" when the water change does come around. I do 20-25% weekly.
