One of my favorite parts of working on something like this is that since I’ve never done it before I’m thinking of new ways to make the project work better as I go. The coat hanger wires were really tough to bend since the pieces I’m using are so short. It was also starting to rip the yogurt containers. Zip ties are easier to put on and are gentler, maybe stronger in the long run. I switched to Chinese take out containers for a similar reason. They are a little thicker plastic so they won’t rip a easily. Also, now I don’t have to worry about consuming 15 tubs of yogurt in a few days. (even though that might have made for a good party)
The socks came from my paranoia of dirt falling out of the water inlets. Most of the holes are smaller so maybe not a problem but loosing soil is something I really want to avoid. They will be stretched around the inside of the inlets, a barrier between lake and dirt.
All these fixes will be applied to the bins I’m building now but I have to retro fit the socks on the 6 bins I’ve already finished. I’m going to put the sock on the outside and leave the coat hanger since the dirt is already in and sprouts are getting comfortable. Learn as you go I guess.
