I have a small experiment at work where I want to look at the root structure of corn seedling. True aeroponic systems are supposed to produce finer root structures which would be great for imaging roots with a microscope.

Any websites for simple diy aerogarden-like build. I really only need the ability to grown 10-12 seedlings at a time up to about 12 inches tall. We have a plant growth room with lights.

The aerogarden looks like a good option, but since I am more interested in the roots than the plants, from what I can tell its more of a hydroponic system than aeroponic system.

I could do it all with a rubbermaid tub. I mainly need advice on the fogger build and nutrient needs.
