1. and 2. complete plant module. the bottom container is a 40 quart muck tub from a farm supply store and the top is a 3 gal feed pan from the same place. the top of the
medium is 14" from the floor.
3. this shows the only modification you have to do to the bottom container. a single 13/16" hole. no glues, no fittings, no clamps.
4. the tailpiece in place with flow limiting plug in place.
5. same shot with limiting plug removed.
if you look carefully at the base of the tailpiece there are 4 3/16" holes drilled in the top container about an inch out from the tailpiece.
i'll explain all of these plumbing changes later.
