Description

The XL 6 lb All-in-One mushroom grow bag gives you 2 lbs of sterilized 5-grain spawn over 4 lbs of Select Bulk Substrate in one self-supporting bag with a 0.22 micron filter patch and a self-healing injection port — the same inject-incubate-fruit workflow as our 4 lb bag, with more material for bigger flushes.

This XL bag was fruited in our Ecosphere grow tent with the top half of the bag removed.

The XL is for growers who want a bigger harvest without moving to a monotub yet. It fits the same small footprint, and like everything we bag it is pressure-sterilized in our own autoclave and shipped fresh.

Why growers pick the XL All-in-One

  • More material, same workflow – 50% more bag than the 4 lb size, with the same inject, incubate, break-and-shake and fruit steps.
  • Layered and ready – Sterilized 5-grain spawn and bulk substrate are already in the bag — nothing to prep, mix or transfer.
  • Fits a shelf – Bigger runs without the space a monotub takes.
  • Clean start – Pressure-sterilized in-house and shipped fresh.
  • Room to scale – Fruit in the bag, or move the colonized cake into a monotub for more surface area.

What's in the bag

  • 2 lbs sterilized 5-grain spawn blend
  • 4 lbs sterilized Select Bulk Substrate
  • Self-supporting grow bag with a 0.22 micron filter patch and a self-healing injection port
  • Full-color step-by-step instructions with photos, plus online video help

How to grow in it

  1. Inoculate. Wipe the port with alcohol, then inject 5–7cc of spores or about 10cc of liquid culture into the grain section. Not sure how many syringes to buy? Use our syringe calculator.
  2. Incubate. Keep the bag around 72–76°F until the grain is about 75% colonized.
  3. Break and shake. Mix the colonized grain through the substrate, then let the bag finish colonizing — typically 10–14 days.
  4. Start fruiting. Give the bag indirect light, fresh air and humidity once it is fully colonized.
  5. Harvest. Open the top and mist the inside walls as needed, or transfer 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, additional flushes and troubleshooting with real grow photos.

Which format fits you?

Option Best for Space Yield
4 lb All-in-One bag Beginners and simple grows Very minimal Moderate
6 lb XL All-in-One bag Bigger flushes, same workflow Low Higher
Monotub Scaling up More needed Highest

Faster startsLiquid culture usually colonizes faster than spores. Our QuickCulture Mini liquid culture jars turn a spore syringe into vigorous liquid culture before you inoculate your bag.


Common questions

How is the XL different from the 4 lb All-in-One?

The XL holds 6 lbs instead of 4 — 2 lbs of 5-grain spawn and 4 lbs of Select Bulk Substrate — so there is more material for larger flushes. The steps are the same.

How much spore solution or liquid culture should I use?

Inject 5–7cc of spores or about 10cc of liquid culture into the grain section through the self-healing port.

How long does the XL take to colonize?

Break and shake at about 75% grain colonization; the bag typically finishes colonizing 10–14 days later at 72–76°F. Liquid culture is usually faster than spores.

Can I fruit it in a monotub instead?

Yes. Many growers fruit right in the bag, but you can move a fully colonized cake into a monotub for more surface area.

Is this the same as the Wood Lover's XL kit?

No. This bag is our standard XL All-in-One. The Wood Lover's XL kit uses a hardwood-based substrate for wood-loving gourmet species and includes a liquid culture syringe.
