Custom 5 pack Spawn Box is a mix and match that you can customize. Choose any mix of 5 spawn bags to suite your needs. Pick from: 

  • Blue oyster (MS 43),
  • Lion's mane (POW),
  • Gold oyster (PC),
  • Black Pearl,
  • Chestnut (PA),
  • Maitake (9827), or
  • Shiitake (3790).

(Example: 2 blue oy, 2 ch, and 1 bp for a total of 5 spawn bags) Need more than 5? Add another Custom 5 pack or just double or triple your order.

  • Blue Oyster - Pleurotus Ostreatus - MS43- An aggressive blue oyster typically colonizes bulk substrate in 10-12 days before pin set. Pin sets start out dark gray. As the mushrooms develop they may turn light blue/gray to brown (depending on environment). With a massive first flush MS43 does not disappoint. 
  • Lion’s Mane - Hericium erinaceus - strain POW- Sometimes called Pom Pom, and the bearded hedgehog as these are just some of the names associated with this versatile mushroom. The mycelium growth for this fungus tooth mushroom is wispy and faint. Then before you know it you will see clusters of primordial growth. A flavor and texture that has been compared to crab meat (you decide). The many uses (fresh, dried, or in a tincture) make it a must for any mushroom cultivator. Typically colonizes bulk substrate in 10-12 days (given proper environmental conditions).
  • Gold Oyster (PC) - Pleurotus citrinopileatus- The bright yellow/ gold color of this species is certainly an eye catcher at any market stand. Typically colonizes bulk substrate in 10-12 days (given proper environmental conditions). Colonization/ Incubation times based on Earth Angel Mushrooms fruiting block production times and substrate..

  • Black Pearl - Pleurotus ostreatus hybrid- When you first see this beautiful oyster hybrid you will notice the mycelium start to develop a black dense pin set that expands out into a thick stem similar to King trumpet. Another similarity to King trumpet, the Black Pearl has a 3 week colonization time on bulk substrate. Grow Black Pearl as part of one of our custom Packs. 
  • Chestnut - Pholiota adiposa has a unique nutty flavor and a cap that is unmistakable. When fruiting be sure to pick them early as they like to drop a lot of spores. Not a fast colonizer, this species takes its time in the colonization/ incubation room. Typically colonizing bulk substrate in 4-5 weeks (given proper environmental conditions).
  • Maitake - Grifola frondosa - strain 9827 is a commercial strain that is currently being cultivated.  Maitake is commonly refered to as Hen-of-the-Woods.
  • Shiitake - Lentinula edodes - strain 3790, is one of the most widely cultivated shiitake strains. Not for the novice or the impatient as all shiitake strains typically colonizes bulk substrate in 8 weeks  (given proper environmental conditions).


Note: Colonization/ Incubation times based on Earth Angel Mushrooms fruiting block production times and substrate.

Each 6 lb. spawn bag can be used to inoculate up to 30- 10 lb. bulk substrate bags. Not going to use all these bags in a week? Don't worry, just refrigerate unopen bags to use at a later date. Once received, we recommend using spawn bags within a month for best results.
