I have been thinking about how to setup my greenhouse here in Arizona and found a growing operation that uses grow towers to produce food. Based on what I'm seeing in the design it looks like a great idea for emersed aquatic plant growth. Anyone have any experience with these for aquarium plants? It would be kept in a greenhouse to maintain humidity and control temp. The thing I like about this idea is the space needed per plant grow. Much more economical space wise.
