Product Details

Our mushroom Mini-Farm grow kits are handmade on our farm in Moss Landing, CA. Crafted with the same technique we use for all of the organic mushrooms production on our farms.

We guarantee your first crop. If you follow the instructions the grow kit may produce 3-4 harvests but each grow kit is handcrafted and can have different results.

If no custom selection is made, an assortment of our freshest mushroom Mini-Farm grow kits will be delivered to you!

How to use?

If you have problems with the Mini-Farm Your Mini-Farm is guaranteed to produce mushrooms if the instructions are carefully followed. Direct sunlight, exposure to heat, and excessive drying can all damage or destroy the living culture of the Oyster mushroom (a species of Pleurotus ostreatus), so avoid these conditions. Sometimes the appearance of the mushrooms will follow a different rhythm than the one described above; if this happens, watch patiently. If you experience a problem with excessive drying during one crop, just remove the affected mushroom, mist well, reclose the bag, and the next crops should be fine. If the drying was caused by too-drafty condition, give the Mini-Farm more protection, such as hanging a plastic sheet to block the wind. If mold growth occurs on the Mini-Farm, remove the affected area with a knife, making a shallow cut, and throw the contaminated portion away, while continuing to follow the general instructions in that stage of development. Remember, the Tree Oyster Mushrooms thrive in the cool moist environments so try to provide these conditions.

Pre-Growth Storage 

Place your Mini-Farm in an indoor spot where it will receive some indirect sunlight, and will also be protected from heat and drafts. Although the Oyster mushroom can tolerate temperatures between 32° to 85° (or somewhat warmer for short periods), the very best results will occur between 50° and 65°. Above the mushroom will appear unpredictably, and may be of lesser quality. Try to locate a cool spot for your Mini-Farm. Place the Tree Oyster box down on the farm informational side down. Pull the tab located at the logo face of the box and expose the inner Mini-Farm. Next with a sharp knife cut two vertical lines equally spaced apart along the length of the block.
Locate the extra plastic bag located in your box and with a pair of scissors cut 10 x-shaped holes about ½ inch size into one half of the bag. The small holes you make will allow the mushroom culture to breathe without drying out. Open the bag and tent over the box with the newly cut x’s o the back si e of your box. Leave the uncut side of the bag loose in the area where the mushrooms will grow.

Storage when MiniFarm is Growing
Watch your Mini-Farm daily for the first signs of activity. Within a week or two you will begin to see some tiny, whitish “pinheads” appearing on the upper surface of the substrate. These will grow rapidly and soon will have the appearance of tiny Oyster Mushrooms. When mushrooms start to develop begin lightly misting the walls of the
plastic tent (not on the block directly) once or twice a day. If the bag is not perforated enough, or soon enough, the oysters inside will appear long and tubular, with tiny caps. Correct this by moving the air hole side of the plastic bag closer to the mushroom growing area of the box (and mist more). Similar problems may develop if there is a
lack of light so just move the farm closer to the light source.

You will be amazed at how rapidly your Oyster Mushrooms will grow; they should double in size every 24 hours, unless it is too cold. Tree Oyster Mushrooms can grow to be several inches across, but they are at their flavorful prime when the caps are between one and two inches across, before the outer margin of the cap begins to curl
upward. Lift the plastic tent from around the Mini-Farm and keep to use again. You want to pick Tree Oyster by grasping the base of the stem between your fingers, then pulling them free leaving as much of the block intact as possible. Your Tree Oyster crop can be stored in the refrigerator for up to one week in a brown paper bag until you are ready to eat them, but they are delicate mushrooms and are definitely at their best when fresh off the farm.

Second and Third Flush Production
After the first crop has been harvested, use a clean knife to lightly scrape off any “runts” that were left behind, position the plastic tent so as the air holes are to the back side of the growing area and give the inner plastic wall another good misting. Tighten the bag and tuck any excess plastic under the box leaving the growing area void
of much growing space and air. Return the MiniFarm to its cool, protected spot and allow it to rest for a few days, start watching for your Mini-Farm to begin to produce its next crop of Tree Oyster Mushrooms. Follow the above steps just as you did for the first crop. The entire crop cycle can be repeated every one to two weeks. Our Mini-
Farm will typically produce three or more crops when the above steps are followed.

Soaking the MiniFarm
With time your Mini-Farm may lose so much moisture on one side that it will stop producing mushrooms. If two weeks pass without a new crop emerging, you can try this: open the box and take out the bag of substrate. Flip around the top of the bag to expose the opposite long side of the block. This is the new growing side. Place the
substrate bag back into the box, recut two new vertical lines and restart the growing process.

Block Disposal
Even with the best of care, the MiniFarm will eventually have transformed its entire food reserve into the Oyster Mushroom you have enjoyed. Now it may be retired to your garden where it will enrich your soil. Should you wish to get another Mushroom MiniFarm we have more Oysters, and if you would like to try something new we have a
Shiitake, Pink Oyster, and Lion’s Mane as well.


  1. How many flushes can I expect from my block?
    With ideal growing conditions, your block could produce 2-3 and maybe even up to 5 flushes! Make sure that your block doesn’t dry out or reach extreme temperatures to have the best chance of multiple flushes.

  2. How long can I store my Mini-Farm before activating?
    Our shiitake, lions mane, yellow oyster and blue tree oyster mushroom grow kits will hold well under refrigeration for up to two weeks. Pink oysters are a tropical species and should be kept outside of refrigeration for up to two weeks.

  3. What are the ideal growing temperatures?
    Ideal growing temperatures are between 50-65 degrees Fahrenheit, and mushrooms can survive and thrive in higher or lower temperatures as well, but for best results we recommend not putting your mushroom block in significantly higher or lower conditions. If you want to delay activating your mushroom mini-farm, you can refrigerate it for up to 30 days, except for the Pink Oyster. Pink Oyster are a tropical strain that prefer warmer temperatures and will not perform well after being refrigerated.

  4. What should I do with my block after it is done growing?
    Your block will make a great addition to an outdoor garden as mulch for fruit trees, or as a soil amendment. You can break up the block and spread it around the base of a tree, or put it in a garden bed. With some moisture and shade it will likely produce more mushrooms!
