Our take on the Mushroom Grow Kit (Quick Kit)

The Out-Grow Quick Kit is a two-bag substrate set for growing gourmet mushrooms at home. It pairs a 1-pound sterile rye berry bag, with injection port and 5-micron filter patch, with a 1-pound manure-based bulk substrate. You supply the culture: inoculate the rye, wait 5 to 6 weeks, then mix into the manure bag for another 4 to 6 weeks. It suits growers who already have a clean culture and patience; rivals that ship a live culture or a ready-to-fruit block cut out the longest steps. Ratings are middling at 3.8 of 5, so expect a kit that works when your technique is clean rather than a push-button harvest.

What reviewers say

  • 3.8 / 532 ratings

Ratings sit at 3.8 of 5 across 32 ratings, so reception is mixed. Buyers treat it as a workable substrate kit rather than a guaranteed harvest.

What people mention
  • SterilityPraisedBuyers say the pre-sterilized bags save the messy prep step.
  • Colonization timeCriticisedThe 9 to 12 week total wait frustrates growers expecting faster results.
  • ContaminationMixedSome bags colonize cleanly while others stall or spoil, which growers tie to technique.
  • Culture neededCriticisedBuyers note the kit has no mushroom culture, so a separate purchase is required.
  • ValueMixedGrowers weigh the two substrate bags against buying rye and manure separately.

About the Mushroom Grow Kit (Quick Kit)

The Out-Grow Mushroom Grow Kit (Quick Kit) is a set of two pre-sterilized substrates for growing gourmet mushrooms at home. One bag holds organic, hydrated, sterilized rye berries for making spawn. The other holds a manure-based substrate that serves as the bulk substrate.

The rye bag has a self-healing injection port and a 5-micron filter patch for gas exchange. The bulk substrate is made from horse manure and fortified with nutrients.

To use it, inoculate the rye bag with 4cc of a gourmet mushroom culture and shake to distribute it evenly. Let the rye colonize at room temperature for 5 to 6 weeks. Then break up the mycelium, mix it into the manure substrate bag, and seal the bag. Let it colonize at room temperature for another 4 to 6 weeks. Mushrooms can fruit directly in the bag or in a fruiting chamber.

Questions and answers

Does the kit include mushroom spawn or culture?
No. It contains only the rye berry bag and the manure substrate bag. You add about 4cc of your own gourmet mushroom culture through the injection port.
How long until mushrooms appear?
Plan on 5 to 6 weeks for the rye bag to colonize, then another 4 to 6 weeks after mixing into the manure bag. Fruiting comes after that.
Can I fruit mushrooms in the bag?
Yes. The kit is designed so you can grow directly in the bag or move the colonized substrate to a fruiting chamber.
How should I store the bags before use?
Up to 4 months at room temperature or 6 months refrigerated. Keep them sealed until you inoculate.
Which mushrooms can I grow with it?
The manure-based bulk substrate suits manure-loving gourmet species. Check your culture's preferred substrate before starting.
Is it good for beginners?
It is beginner-friendly in setup, but success depends on clean technique. A kit with a live culture is easier for a first grow.
Where is the Mushroom Grow Kit (Quick Kit) cheapest?
At Walmart, for $16.95, as of our latest check.
What do buyers say about the Mushroom Grow Kit (Quick Kit)?
