About this item

• Premium CVG Bulk Substrate — Includes 500g coco coir, 500g vermiculite, and 100g gypsum, the ideal coco-coir, vermiculite & gypsum blend for mushroom cultivation.
• Just Add Boiling Water — Easily hydrate in a 5-gallon bucket using 16 cups of boiling water, then pasteurize for 24 hours to reach optimal field capacity.
• Large Yield for Multiple Flushes — This dry mix makes about 9 lbs of hydrated bulk substrate, enough for two full monotub grows or other fruiting setups.
• High Moisture Retention & Aeration — Coco coir offers water-holding capacity, vermiculite adds air pockets, and gypsum stabilizes pH — creating a balanced environment for strong mycelial growth.
• Versatile & Beginner-Friendly — Perfect for spawn-to-bulk transfers (S2B) in monotubs, trays, or filter bags; a popular and reliable choice for both new and experienced mycologists.
