Fresh mushrooms at home without the waiting. Our Ready-to-Fruit Grow Bag arrives fully colonized and ready to fruit. We sterilize a supplemented sawdust substrate, mix in our grain spawn by hand and incubate the bag in our grow room until it's white all through. Open it, give it fresh air and humidity, and your first harvest is on its way. Many bags ship with small mushrooms already starting to form.

Why Choose This Bag:

  • No incubation needed. We do the colonizing for you, so the bag is ready to fruit the day it arrives.
  • Simple to grow. There's no injecting, mixing or sterile work. Open the bag, keep the air humid and harvest.
  • First flush guaranteed. Most bags then give a second flush, and sometimes a third.
  • Two sizes. The 10 lb bag holds about three times the substrate of the 3 lb bag, for bigger harvests.

What's Included:

  • Small: 1 fully colonized 3 lb (1.4 kg) grow bag of your chosen species
  • Big: 1 fully colonized 10 lb grow bag of your chosen species

Ready to Ship:

We keep colonized bags in stock, so there's no preparation wait before shipping.

How to Fruit:

Small Bag (3 lb)
  1. Open the bag as soon as it arrives. Spray the outside of the bag and your scissors with rubbing alcohol and let it dry.
    What you need: the grow bag, a spray bottle of rubbing alcohol, a bucket, two supports and a clear plastic bag
  2. Pioppino and King Oyster: cut the top of the bag open above the substrate. The mushrooms grow inside the bag, so there is no tent and no spraying needed.

  3. Lion's Mane: press the air out, fold the top down tightly and hold it with rubber bands or tape. Cut one slit in the side, 5–10 cm long, or an X.

  4. Lion's Mane: lay the bag on its side in a bucket with a little water in the bottom, raised above the water, with the cut facing up. Cover the bucket loosely with a clear plastic bag. No spraying needed while there is water in the bottom.

  5. Keep the bag in indirect light. Small mushrooms usually appear within 7 to 10 days.

Big Bag (10 lb)
  1. Open the bag as soon as it arrives. Spray the outside of the bag and your scissors with rubbing alcohol and let it dry.
  2. Pioppino and King Oyster: cut the top of the bag open above the substrate. Small mushrooms will start forming inside the bag.
  3. Lion's Mane: press the air out, fold the top down tightly and hold it with rubber bands or tape. Cut one diagonal slit in the side, about 10–15 cm long.

  4. All species: big bags need extra humidity to fruit. Cover the bag loosely with a large clear plastic tent and mist inside the tent 2 to 3 times a day, without spraying the mushrooms directly. Or place the bag in a fruiting room with controlled humidity.

Fruiting temperatures differ by species. Lion's Mane fruits best at 18–24°C (65–75°F), Pioppino at 13–18°C (55–65°F) and King Oyster at 15–21°C (60–70°F).

Flushes:

Your first flush is guaranteed. Most bags then give a second flush and sometimes a third, each usually smaller than the one before. After a harvest, rest the bag for about a week, then start spraying again to bring on the next flush.

Storage:

For best results, open the bag soon after it arrives, and right away if small mushrooms are already forming. If you need to wait, keep it in a fridge (2–8°C) for up to 3 weeks, then let it reach room temperature before opening. Do not freeze.

Quality Guarantee:

Every bag is inspected before shipment, and we guarantee the first flush. If your bag arrives contaminated, contact us within 24 hours with clear photos for a free replacement. If no mushrooms appear within 14 days of opening, contact us with photos of the bag and your setup, including temperature and humidity, and we will send a replacement. We replace bags rather than issue refunds. Second and third flushes depend on growing conditions.
