Now that you have read David’s description, you might be interested in our adaptation of the idea to New England.
First, we decided to build our composter in a hoophouse, to extend the season of fungal activity. This entailed modifications to the pipes so that they could be withdrawn inside a structure that was not twice as tall as the reactor.
Second, we determined to irrigate the reactor daily by hand, rather than by a drip system, since we did not have a frost-free water supply to the hoophouse yet wanted to reactor to be functional in early spring and late fall.
The following pictures show our construction progress.
