I saw this guy a while back. https://www.youtube.com/watch?v=lzcC6zkDDiY https://www.youtube.com/watch?v=lzcC6zkDDiY I think he got a lot of flack for pointing out that the zip-grow towers are way overpriced and you can DIY them yourself reasonably well. There really isn't anything too-complicated about the ZipGrow towers, other than that they use a sponge as a media.
