Modified metallic and 5PP lids for liquid culture with self therapeutic inoculation port and breathable syringe filter. Photo: D!NGO Use heat resistant higher temp silicone, like RTV (Amazon), to attach and seal all factors over the lid.
With this tutorial, We are going to guidebook you through the entire process of creating a four% carbohydrate broth liquid culture, especially customized for mushroom cultivation.
