I've been growing in homemade boxes for a few years now. I don't get my biggest or best plants, but I get the most consistent results, with the least amount of disruption from heavy rains, and the fewest pests.
For my garden, I have a few different "models" of container. Most of them are based off of a 27 gallon tote, with corrugated pipe reservoirs - a slight modification of the "Albo Tote".

A couple of my containers are built from 55 gallon plastic (poly) drums. I cut off the top, slit the sides, and press it down into the drum to form the reservoir.
All of these are plumbed to my rain barrel(s). I have a 3/4" PVC line running from the rain barrel, along side the containers in rows. Each container is plumbed to the 3/4" line, and has a shut-off valve, so that I can fill the reservoir. When it's full, I know, because the container pisses out of the drain hole.
Now, I'm only posting this to validate the concept. It can take a few variations, but ultimately, this is a very good growing system. I don't use hydroponic nutes, and will not. Personally, I just use a good organic fertilizer up top, and I don't cover the container. But the point is, you can, and it works. Either way, it works. The only way you're going to mess up growing with this system, is A) don't give it food of SOME kind, B) don't leave proper air space in the reservoir, C) don't keep some water in it.
