-
To get the best growth, we recommend pairing your fruiting blocks with a growing system like the BoomRoom, a monotub, or a Mella fruiting chamber to create the optimal growing environment for your mushrooms.
-
The average fruiting block will produce between 1-2 lbs per flush (less in subsequent fruitings). And depending on the species, you can expect 1-3 fruiting cycles per block. Note that some of the more advanced species are harder to get subsequent fruitings.
-
Yes! Fruiting blocks are mushroom grow kits. But, unlike our boxed countertop Spray & Grow kits, these are larger and grow in bags. Our fruiting block kits are made from vigorous edible mushroom mycelium grown on a proprietary blend of hydrated and sterilized hardwood sawdust with other organic amendments that mushrooms love! Just follow the directions specified for each species (in the instruction book provided) and watch your mushrooms grow!
-
We want every grow to be a success! The team at North Spore will select kits with the highest chance of optimal growth based on the time of year, so you’ll be sure to have an abundance of fresh edible mushrooms for your next meal. Plus, our ability to focus on making large numbers of select species each month means we can pass along the savings to you.

Mushroom Love
These all fruited within a week in a Martha tent, and again a few days later. After the second fruiting I tuck into our woods and I get more mushrooms if I can beat the slugs. I am very happy with the subscription box!

Not worth the price
I enjoyed trying out the fruiting block subscription; however, had difficulty with yields in max yield monotubs (likely my fault) and with the high cost of shipping added, makes it exponentially more expensive than buying the same gourmet mushrooms at Whole Foods.

Amazing
Opened very first box of subscription and all three blocks were packed with mycelium! Fast shipment and very informative on the books for growing included in box keep it up North Spore you guys and girls rock!

Excellent results
My first subscription box is doing great! I couldn’t start them immediately, because I was going to be gone for a couple of weeks. I didn’t have room to refrigerate them, so I left them in the box near the AC vent, hoping for the best. No problem! I’m growing them in a monotub with perlite in the bottom, so they have a nice, humid environment. A few weeks after receipt, I started the lion’s mane and the Italian oyster. The oyster started pinning on the same day I cut them open, and were ready in less than a week. Shortly after that, I started the pink oysters, and they are close to ready, again in about a week. And the lion’s main is moving right along at its own pace. Very easy to get excellent results! I’m browsing recipes, gonna be cooking a lot of mushrooms.

'The Blocks Box' Organic Mushroom Grow Kit Subscription
Blocks Box subscription is awesome and the North Spore support team was amazing as well! The first flush of golden oysters and the first flush of pink oysters flopped, due to a power failure. After removing the wilted mushrooms, both blocks are growing mushrooms. I hope to soon harvest both blocks. I'm not sure about what the king trumpet block is doing, but I may have to remove the pins from it and try again. The block seems to have stalled. I really appreciate all the help that the North Spore support team has offered during this process. Watching the mushrooms grow has been an amazing experience. I look forward to receiving my next shipment as I feel better prepared to work with mushrooms, and I want to feel confident with grow kits before moving on to more advanced mycological activities. Thanks North Spore!

Loved this box!
I got a great flush of mushrooms from these blocks. My friends love seeing what can be grown and it is always so exciting to show them. I use my Boom Room set-up to have a good environment for my mushies to grow in.
