Description

A wholesale case of 10 All-in-One mushroom grow bags, 4 lbs each.

The 4 lb All-in-One is the simplest way into mushroom growing we sell, which is what makes it easy to sell for a shop and easy to hand to a new grower. No tub, no separate substrate prep, no mixing: the grain and substrate are already in the bag.

Why growers and shops pick the 4 lb All-in-One

  • Everything in one bag – Sterilized grain spawn and bulk substrate share one self-supporting filter bag, so there is nothing to mix or transfer.
  • Easy first grow – Inject, incubate, break and shake, fruit. It is the least equipment-hungry way to run a bulk grow.
  • Small footprint – A single bag fruits on a shelf or counter — useful for customers without room for a tub.
  • Clean start – Pressure-sterilized in our own autoclave and shipped fresh rather than pulled from long-term storage.
  • Case pricing – Ten bags at a lower per-bag cost than retail, for resellers and growers running several at once.

What comes in the case

  • 10 × 4 lb All-in-One mushroom grow bags
  • Per bag: 1.75 lbs sterilized milo, millet & rye grain
  • Per bag: 2.25 lbs CVG bulk substrate (coco coir, vermiculite & gypsum)
  • Self-supporting grow bag with a 0.22 micron filter patch and a self-healing injection port
  • Step-by-step printed instructions with each bag

How to grow in an All-in-One bag

  1. Inoculate. Wipe the injection port with alcohol, then inject 4–5cc of spores or 5–10cc of liquid culture into the grain.
  2. Incubate. Keep the bag at 72–76°F, out of direct light, until healthy mycelium is spreading through the grain.
  3. Break and shake. At roughly 50–75% colonization, break up the grain and mix it into the substrate to speed up full colonization.
  4. Start fruiting. Once fully colonized, give the bag about 12 hours of indirect light a day and introduce fresh air.
  5. Harvest. Cut the top of the bag and mist the inside walls as needed to hold humidity. Harvest directly from the bag, or move the cake to a larger fruiting setup.

Full walkthrough: the All-in-One Grow Bag Guide covers inoculation, colonization, break-and-shake timing, fruiting conditions, harvesting and troubleshooting with real grow photos — worth sharing with your customers.

Common questions

What is an All-in-One grow bag?

It is a sterilized mushroom grow bag that holds grain spawn and bulk substrate together in one sealed, filtered bag. You inject spores or liquid culture, let the grain colonize, mix it into the substrate, and fruit in the same bag — no tub or separate substrate prep needed.

What is in each 4 lb bag?

Each bag has 1.75 lbs of sterilized milo, millet and rye grain and 2.25 lbs of CVG bulk substrate (coco coir, vermiculite and gypsum), inside a self-supporting bag with a 0.22 micron filter patch and a self-healing injection port.

How much spore solution or liquid culture should go in each bag?

Inject 4–5cc of spores or 5–10cc of liquid culture through the injection port. Liquid culture generally colonizes faster than spores.

How should I store the case before use?

Inoculate as soon as practical — the bags are shipped fresh after sterilization. Until then, keep them sealed in a cool, clean, dry spot out of direct sunlight, and do not open the bags.

Can I get retail boxes?

Retail boxes are available by request only. Contact us before placing your order.

Can I use a discount code on a wholesale case?

No. Additional discount codes cannot be applied to wholesale case pricing.
