If a grow kit has let you down before
You are not the reason it failed last time.
Most grow-kit disappointment comes down to one thing: a block that was contaminated or under-colonized before it ever reached you. We have cultivated specialty mushrooms on the same Moss Landing farm since 1982, and every Mini-Farm is built from meticulously pure cultures, spawn, and substrate — then guaranteed to fruit.
That is why so many of our growers came to us after another kit failed them — and stayed.

I ordered the shiitake log as a birthday present for an 11-year-old boy. He said it was the best gift ever. He has had his first harvest and reported that he and his mom made mushroom and wild rice soup. Success!
The mushrooms started to brown and stink, right after a few mushrooms started to grow. We harvested a handful of mushrooms and the rest all went bad/stinky.
The mushrooms began to sprout within a week. The first harvest was stir fried and the second was stewed. They were delicious. Much better than the dried shiitake mushrooms you purchase in the stores. Growing the mushrooms isn’t difficult and it is a lot of fun.
Got just over 1 lb of Shiitake from the first round after following instructions. Super easy and clean. Hopefully we get another one or two flushes! Mushrooms were delicious.
It was a-mazing how fast the kit started working and how soon I was able to harvest about 1.5 lbs of beautiful caps. They went from knobs to "pick-me!" In a few days. Now it's resting and will hopefully be making a second flush in the new year.
I ordered two. They both fruited quickly and readily. I harvested my first mushroom within a week of getting the kit. One kit did start growing green mold however and some of the mushrooms were black at the bottom.
OMG the biggest and most delicious Shitake I ever saw. We used a trick they do in Japan and put the bag, mostly covered, outside during a thunderstorm and the caps grew exponentially larger by the next day.
The Mini-Farm is one of our most-gifted kits — a birthday surprise, a holiday host gift, a science experiment a kid will actually remember. It arrives ready to grow, with everything needed to harvest in the first week. Gifting it soon? Set it up within seven to ten days of arrival for the best first flush.
Located in northern Monterey County in the coastal town of Moss Landing, our eight-acre farm sits above the Pajaro River, overlooking the Pacific. The steady ocean breeze and coastal fog make it an ideal place to cultivate mushrooms.
The same Shiitake mushrooms our chefs buy fresh is the strain colonizing your Mini-Farm — grown on sterilized sawdust substrate, the way the Garrone family has done it for more than forty years.
