Looking for wholesale all-in-one mushroom grow bags? Our Inject & Forget bags hold sterile grain and CVG substrate together in one bag, sterilised at 121°C for 2.5 hours and ready to inoculate through the self-healing injection port. No spawning to bulk: inject, leave it to colonise, then fruit.

Made for growers, farms and resellers, in 1.2kg and 2.4kg bags and wholesale quantities from 25 to 1,000+. Every option shows the price per kg. Each bag comes with instructions. Spores and liquid culture are not included.

Which bag each size comes in

• 1.2kg: Unicorn 3T
• 2.4kg: Unicorn XLS-B, one of Unicorn's largest bags

What you can grow

The grain and CVG mix is ideal for therapeutic varieties, and also grows oysters (blue, grey, pink, king and yellow), enoki, pioppino and more. Wood-loving species like Lion's Mane, Reishi and Shiitake prefer a hardwood substrate, so for those see our wholesale Masters Mix.

Genuine Unicorn bags only. Every bag we ship is a genuine Unicorn bag, the industry-leading mushroom grow bag made in the USA. We never cut corners with cheap generic bags. Unicorn bags are built to handle the autoclave and their filter patches are consistent bag after bag, so you get cleaner colonisation and fewer losses.
