We took over a farm that was running mostly on Hydroponics and will be switching the design around a bunch so have a bunch of gear. A whole bunch of irrigation lines, drip emitters, pumps, tanks, Gro-slab fiber in micro, medium and long slab format, a few water reservoirs, and even a home made dehydrator. Swing by and take a look at what you think you could use, make an offer in cash or labour trade of hauling the crush rock from the greenhouse out to the driveway for a few hours.
