THROUGH THE Cultivator's LENS Highlights

  • You are scaling up your mushroom cultivation operation because your current media falls short on nitrogen and nutrient density for manure-loving species
  • You are setting up a new round of inoculation because you need a reliable, fully sterilized growing medium that eliminates contaminants right out of the bag

  • The 25 percent rabbit manure blend delivers a nitrogen-rich profile that supports rapid colonization.
  • Sterilization at 15 PSI for 8 hours produces a clean medium built for manure-loving species.

  • Growers running single tubs or scaling up production say they achieved vigorous mycelium growth and healthy yields batch after batch
  • Cultivators working with button and portobello mushrooms say the balanced slow-release nutrients helped reach full yield potential

Uncle Myc's Manure Blend Mushroom Substrate

Manure-loving mushroom species need a genuinely nutrient-dense substrate to reach their full yield potential, and most bagged mixes fall short on that front. Uncle Myc's Manure Blend Mushroom Substrate solves this with 25% locally sourced rabbit manure, naturally rich in nitrogen and essential minerals, delivering the balanced, slow-release nutrient profile that drives vigorous mycelium growth. To achieve the best results, we recommend inoculating your genetics into an Uncle Myc's Rye Berry Grain Sterilized Mushroom Spawn Bag before transferring to this blend.

Every batch starts with fresh, chemical-free manure sourced directly from small, local farms — never commercial feedlot waste. From there, the substrate is hydrated to field capacity and fully sterilized at 15 PSI for 8 hours, eliminating contaminants and producing a clean, reliable growing medium built specifically for manure-loving species.

Whether you're a home hobbyist running a single tub or a dedicated cultivator scaling up production, this substrate is available in multiple sizes to match your operation. For growers seeking a simplified process, the Uncle Myc's All-In-One Mushroom Spawn Bag offers a convenient alternative by combining growth stages in one bag.

Frequently Asked Questions

What makes this substrate different from standard mushroom substrates? +

It's blended with 25% locally sourced rabbit manure, which is naturally rich in nitrogen and minerals. If your species requires a different nutrient profile, we also carry Uncle Myc's CVG Supplemented Bulk Substrate for more general-purpose applications.

Which mushroom species is this substrate best for? +

It's formulated specifically for manure-loving species like button, portobello, crimini, and almond mushrooms, as well as Shaggy Mane. These species thrive on the nutrient profile that manure-based substrates provide.

Is the manure safe and chemical-free? +

Yes. The manure is sourced directly from small, local farms rather than commercial feedlots, and every batch is hydrated to field capacity and sterilized at 15 PSI for 8 hours before packaging.

Do I need to sterilize or prepare this substrate myself? +

No. The substrate arrives fully sterilized and hydrated to field capacity, so it's ready to use straight out of the bag once mixed with your spawn. If you are cultivating wood-loving culinary mushrooms like Lions Mane or Oysters, you should use our Uncle Myc's Master's Mix Bulk Substrate instead.

Which size should I choose — 2lb, 4lb, or 8lb? +

The 2lb bag suits small test batches, the 4lb size fits most home setups, and the 8lb bag is built for larger or multi-container grow operations.

Can beginners use this substrate? +

Yes. Since it arrives pre-hydrated and sterilized, hobbyist growers can go straight from spawning to colonization without needing specialized equipment or prep experience.
