  • Made-to-order mushroom spawn is considered to be better than pre-packaged spawn because it offers several advantages. Here are some of the reasons why made-to-order spawn is better:

  • Freshness: Made-to-order spawn is produced fresh just before it is sent to the customer, which ensures maximum viability and vitality of the mycelium. 

  • Pre-packaged spawn, on the other hand, may have been sitting on a shelf for an unknown amount of time.

  •  Customization: With made-to-order spawn, customers can specify the species and strain of mushroom they want to grow, as well as the type of substrate they prefer. This allows for a more tailored and personalized growing experience.

  • Quality Control: When spawn is made to order, it can be carefully monitored and quality-checked to ensure that it meets the highest standards. This is not always possible with pre-packaged spawn.

  • Reduced Waste: With made-to-order spawn, customers only receive the amount they need, reducing the risk of waste and spoilage.
