Boris The Beetle Posted March 20, 2020 Report Share Posted March 20, 2020 I am making some kinshi bottles right now using hardwood sawdust and Pleurotus ostreatus (liquid culture to rye grain to sawdust/bran). I will be using PP5 32oz deli containers with syringe filters (or just micropore tape) in the lids for air exchange. Does anyone know how long after full colonization of wood substrate I have to wait before I can add larvae? From my understanding, the mycelium needs time to break down the wood lignin but I'm not sure how long this takes. I'm planning to use this kinshi for various Dorcus species (alcides, antaeus, and curvidens). Additionally, if I let the mycelium go on forever without fruiting, would the sawdust eventually reach a point of degradation that would be suitable for megasoma/dynastes? I attached photos of some bags I have colonizing. The strain I have is very aggressive. A 1 quart jar of rye berries fully colonized after 4 days with a 1 tablespoon grain-to-grain transfer. The 5lb bags are around 65% colonized right now. I have 2 more jars of rye grain that I will use to colonize more jars as well as some 32oz tubs of sawdust/bran. Edit: I forgot to mention these bags are for us, not the beetles. Going to gift the bags to family members as "grow your own mushroom" kits haha Though I did find a report online of someone breaking up the fully colonized bags and filling bottles with already colonized sawdust.
