Is there a good design online for a self-harvesting bin made from concrete? I would think this would be the most cost effective for a permanent design. I am going to attempt to make a ceramic mold for a semi-underground unit this Summer. I may use a terra-cotta planter as the underground part of the unit. I figure a two or three piece design (base, ramps, cover) may work. Also, if my ceramic unit is somewhat decorative, these may be marketable up here. Another idea I have involves hanging an 18" diameter PVC pipe and building the model from that base. I want to get a little more creative than my boring plastic buckets.
If anyone out there has some unique and creative DIY design, I would love to see them.
Should I feel strange for scoping out coffee shops & grocery stores for BSF food sources?
