Just wondering any ideas about using perlite alone as a medium in an ebb & flow set up.

I think that perlite is too fine for use in ebb and flow. You are gonna have small pieces that will clog up your drain line...and...could clog up your pump..if it makes it that far. Use the big clay pellets or grow rocks.

I've changed designs, going with a drip system. Thanks for your info though.
