I actually have a thin layer of small pebbles on the bottom of my pots. The organic matter in the soil mix is high enough that the soil that sifted down into that pebble layer has made contact with the pot itself. The fabric pot acts as a wick and the soil pulls it up from there. There's no need to have any special layer in the pot, although there are a number of growers who do so. The soil will work either way.
I use perlite in the reservoirs but I used pumice in the soil mix. Perlite tends to float to the top over time. I wanted something that would aerate and stay put while it did so. Many growers use perlite and are very happy. Most of them recycle their soil between grows. A no-till garden requires long term thinking - pumice over perlite.
