The grow media is rockwool. Once the sprouts get bigger I'll place the whole thing in a planter with clay pellets on the bottom and a coco/perlite mix on top.
Supposedly it helps keep the coco and perlite from leaking through the planter holes. If I have a lot of successful sprouts I might experiment with just coco/perlite for some. Most of them are various peppers so it's too soon to know if they're successful or not.
what is the white plasticy looking stuff on top? (since it's clearly not soil)
and are those black pipes in the back inlets/outlets?

Yeah those are the fill and drain.
why clay pellets on the bottom?
