Growing with neoprene...anyone else?

I am new to this site, but definitely not new to growing...I've been doing Aero with incredible yields for close to 6 years. My mentor has always taught me to grow using only neoprene collars (no rockwool, no grow plugs, no grow medium at all, except the neoprene the holds the seedling (and plants) in place, with the misters spraying the water underneath directly onto the roots. I am not sure if this is a widely used method, does anyone else do this? Just curious...
