5lb sterile substrate bag for mushroom cultivation, perfect for 55qt monotubs! Ideal for compost/dung-loving mushrooms. Each bag is filled with field-capacity CVG substrate optimized for arid desert conditions. Our CVG blend is proudly made with 100% natural coco coir. 

  • PERFECTLY HYDRATED: We know how frustrating it is trying to grow mushrooms in an over-hydrated or bone-dry substrate. We've honed our procedures to get the perfect hydration every time.
  • OPTIMIZED FOR ARID CLIMATES: Growing mushrooms in the desert is a challenge. Our substrates use 100% natural coco pith selected for its water retention capabilities, hydrated to perfection for use in arid climates. 
  • STERILIZED: Sterile media to prevent hidden contamination and allow for the fungi to establish a healthy microbial environment.
