Turn colonized grain into fat, reliable canopies. WHY SHIITBAG Dialed in by working mushroom growers, ShiitBag is a sterile, manure-based bulk substrate built to push yield on dung -loving species. The recipe’s been stress-tested for years for fast colonization, strong structure, and consistent fruiting—bag, tub, or tent. WHERE IT SHINES Run it in monotubs, filter bags, trays, Martha tents, or humidity-controlled rooms. Fruit straight from the bag or mix to bulk—your call. FEATURES Made from 100% organic materials pH balanced with a complex nutrient profile Proven vigorous mycelial growth Fast colonization and heavier flushes Great aeration + moisture retention Hydrated to field capacity Sterile and ready to use WHAT’S INSIDE A proprietary blend of composted horse manure, coco coir, and targeted supplements—sourced from quality local, organic, and non-GMO inputs. No sketchy additives; just clean, grow-ready substrate. HOW TO MIX (SPAWN:SUBSTRATE) Start with 1 colonized grain spawn bag to 2–3 ShiitBags.Higher spawn rates can speed up colonization and help outcompete contaminants. PRO TIPS Break up and mix thoroughly for even distribution and surface micro-texture. Keep surface conditions dialed (glistening, not soggy) for dense pinsets. Maintain clean technique from spawn to fruit for best results. Heads-up: Know your local laws and species guidelines.
