My friend build his own vacuum former and started manufacturing these trays from thick ABS plastic.
Fuckin engineers, man....
Anyways, the vertical design is inspired by Heath and some other people out there....
Trays are pretty dope, can run them with aero, RDWC, or ebb&flow. I'm sure you can rig up drips, too... I fill em with 5.5" square pots.. You can fit ~18 in a tray. They sell tray lids, too. with netpots.
I kind of took their system and Frankensteined it.
They sell trays/stands individually, so you can take what you need and DIY it.
He is manufacturing these things now. Got really nice shelving.
Whole system takes less than 3.5'x3.5' floor space. And it's cool because it's adjustable, so you can change the levels between all of the trays.
I'm not sure if they are selling these systems yet, but they have a site up, almost ready to go.
