So I am trying to achieve a REALLY hydrophobic surface quality on specific parts of the mycelium material I am developing for outdoor beehive enclosures. I use Ganoderma Lucidum (reishi) to achieve compact and hopefully antiseptic housing for honeybee cuties
The issue with thermal insulation in construction is the condensation that occurs especially during the wintertime if the relative humidity is high in the inner space. If such material does not breath and gets moist enough, it gets mouldy. For a high-quality honeybee life standard, we need to make a good insulating material that can breath (air and water) and would not let the rain-incremental weather in.
I need a really hydrophobic quality on the outer skin of especially the roof part of the hive. I attached a diagram of the dew point that happens on a thick tree wall - where the fibres get saturated…
Question is: If I add pectin (from fruits or powder form), would the fungus cells break it down? and the mycelium tissue would become hydrophobic? Generally speaking, is the fungus what it eats -like us humans? - ??
