Guy Builds Crazy Hydroponic Lettuce Garden In His Living Room

I built this hydroponics setup over my Christmas break. My girlfriend @saysme eats a shit ton of lettuce so I designed this with her in mind. Everything is automatic and on timers. All I have to do is add seedling plugs and fertilizer once a week. The lettuce in the pics at the end is after two weeks from planting the seeds. They should be ready to harvest in a couple more weeks. After each tray is harvested, I'll rotate in fresh seedlings so we always have fresh lettuce in the kitchen. :)
