I hope my mom doesn't see this, its going to be her birthday gift hopefully ;D. I was looking around instructables for good projects for my garden-loving and food-growing mom, and noticed several hydroponic systems. They all looked nice, but I noticed one thing: they all used the nutrient-film or submerged plant technique. I'm no expert, but this seemed bad for the roots. Rot, anyone? I recalled a system I had seen at Walt Disney World in the distant past (OK, 4 years ago :P), where plants roots passed through a nutrient-laden mist. This seemed a better solution to me, allowing the best nature of hydroponics to take root (no pun intended lol): supplying the roots with nutrients while allowing them to breathe and supporting them. I thought about how to create the mist and it hit me: a hose sprayer. Most sprayers nowadays come with an adjuster nozzle to change the flow, so if one were to move it to "mist" position, tape down the handle and attach it to a large submersible pump on a timer, you have a cheap aeroponics system. I'll be writing an instructable when I can, so stay tuned for updates.
