Provenance record
KNF fermentation vessels buried in the Hügelkultur core as a zero-power heating jacket, with a 900 sq ft thermal boundary and a foil-side-down infrared seal.
Exothermic decomposition — including late-season mycelial fruiting — inside the buried vessels sustains microbial activity past the ambient freeze point of the 1,300 ft plateau and raises the baseline root-zone temperature along the canopy window.
Foil-side-down albedo tarping over the buried containers traps ascending soil radiation in the root and vessel zone instead of letting it radiate to the night sky.
