The Unicorn 10A is the compact, mid-small mushroom substrate fruiting bag in the range — a step up from the 4A when you want a little more substrate per bag while keeping things space-efficient. It runs the same 0.5 micron A filter as the rest of the Unicorn fruiting line, so colonisation and gas exchange stay consistent as you scale. Made in the USA since 1990 by Unicorn Bags LLC, the industry's most trusted name in mushroom cultivation bags.

Specifications

  • Filter: 0.5 micron A filter — balanced gas exchange, maintains moisture retention during colonisation without over-drying your block
  • Capacity: Up to 1.8kg of substrate
  • Size: 5" x 4" x 18"
  • Material: 3.0 mil polypropylene — autoclave and pressure cooker safe at 121°C / 15 PSI
  • Side-gusseted, reinforced bottom seal

Why Growers Choose the 10A

  • More substrate per bag than the 4A, still compact enough for smaller grow spaces and shelves
  • The 0.5 micron A filter gives consistent gas exchange without the moisture loss that wider filters can cause
  • 3.0 mil polypropylene handles autoclave and pressure cooker cycles without warping or seal failure
  • Trusted by hobbyists + commercial growers worldwide
