Zones and design
I have a hair brained scheme.
I thought of a design for a flow through system where you use an 8 to 10 foot long pipe, about 20 inches in diameter.
The pipe would be sloped (angle to be determined) and capped at the bottom end (removable). It would be on casters so the pipe could be rotated. The bottom end would be at wheel barrow height. The bottom cap would have a spigot for removing the tea. The pipe would have a beater bar mounted to the inside so when the pipe is rotated it will mix the contents, and aid in the removing of the castings. Comments?
Now the bigger issue, Zones. I live in 8b/9a zone. The system I am proposing would be above ground and mostly shaded. We do hit freezing in the winter and have months of 90+ degree weather. I know that they say the worms like a 60 - 80 degree temperature range. What temperature can they withstand before croaking? I could use heater tape in the winter and possible keep them to 40 degrees, but cooling, ain't gonna happen. Is vermicomposting not an option (for above ground at least)?
