The world needs a simple, relatively high-volume and inexpensive hydroponics setup attractive enough to display in your living room, dining room, or on your patio. It's urban hydroponics -- grow herbs, for example. Make it out of white 6” PVC pipe held in a terraced stack by a saw-cut and finished plywood frame (or something more clever). If you make it, or find it, we want to sell it on Alienlandscapes.biz. Send us e-mail at firstname.lastname@example.org or visit The League of the Brick Moon and join up to discuss.
