Growing mushrooms just got easier!

Join our growing community of year-round mushroom cultivators by subscribing to The BlocksBox – a monthly mushroom kit subscription that features three of our ready-to-grow 5 lb. fruiting block mushroom grow kits. And you won’t just have delicious seasonal mushrooms growing year round – you’ll also save 25%!

How does it work?

The first week of each month, we'll ship you three (3) fully-colonized fruiting block mushroom grow kits, chosen by our staff based on seasonality to ensure the best optimal growth conditions. Choose from two box options, or subscribe to both!

The 'Explorer' Box: Curated for the mushroom grower interested in beginner-friendly species.

  • Each box will feature three (3) fruiting blocks with highly productive commercial mushroom strains, including Lion’s Mane, Blue Oyster, Snow Oyster, Italian Oyster, and Pioppino.

The 'Discovery' Box: Curated for the mushroom grower interested in both advanced and beginner-friendly species.

  • Each box will feature three (3) fruiting blocks with highly productive commercial mushroom strains, including Lion’s Mane, Blue Oyster, Snow Oyster, Italian Oyster, Chestnut, King Trumpet, Black King, Shiitake, and Pioppino.

We're loco for local!

Inspired by the popularity of CSA’s, having a subscription means you’ll be bringing agriculture into your own hands and supporting the ever growing community of mushroom growers. Because there is no food more local than the food you grow at home!

Or, you can find complete instructions listed on the bottom half of all fruiting block product pages.

Can I purchase more than one subscription?

Absolutely! Just select the number of boxes you want when you add the subscription to your cart.

Can I pause or cancel my subscription easily?

Yes! You can manage all of your subscriptions directly in your account. Log in and click "Manage My Subscriptions" to pause, skip, or cancel your shipments. Click here to learn more. 

What is the best way to grow fruiting blocks?

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.

How many mushrooms do fruiting blocks produce?

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.

Are fruiting blocks the same as mushroom kits?

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!

Why can’t I select my own kits?

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.

Frequently Asked Questions

Fruiting block kits are mushroom grow kits, but tend to be larger (5 lbs) and some require a bit more care depending on species. Instead of boxes, they are bagged. We recommend growing them in a fruiting chamber such as a monotub or martha tent set up like our BoomRoom. A controlled environment will produce the best results for the fruiting blocks. And, since these kits are slightly larger, they can produce more mushrooms than our Spray & Grow Kits.

Oyster mushrooms and lion's mane mushroom fruiting block kits are great for beginners because they are reliable producers and require the least amount of effort. Reishi is also great because the mushroom grows in the unopened bag (no special care or fruiting chamber required!)

All kits should grow a minimum of one flush of mushrooms, but with a little patience and skill you can often get a second or third flush depending on the species! After you’ve harvested your first flush of mushrooms, remove any growth from the block and follow these instructions:

⮕ If you have a martha tent or an automated fruiting chamber, leave the humidity and fan running and wait about 2 weeks for new pins to begin forming.

⮕ If you are using a monotub or non-autmated fruiting chamber, open 2x daily and spray blocks generously with water. Try not to expose the blocks for too long to decrease chances of contamination.

⮕ If you don't have a monotub, martha tent, or fruiting chamber cover the block with a humidity tent made from a large plastic grocery bag with LOTS of small, quarter-sized holes. Remove the humidity tent 2x daily and spray blocks generously with water.

Be patient: It's totally normal for it to take longer for mushrooms to appear with each subsequent fruiting. However, if there's no progress after two weeks, it’s a good idea to soak your block.

Soaking your block: Take your block out of the bag and soak in a bowl of cool water. Most species only need to soak for 20 minutes. However, only soak your lion's mane block for 5-10 minutes as these blocks tend to break apart if soaked for too long. After soaking, let the block drain by leaving it cut side down for another 10 minutes or tip it around to let extra water run off. You don't want to leave standing water in your bag, so pat your block dry with a towel before placing it back in the bag.

Note: Shiitake blocks should not be placed back in the bag.

For most species, you should leave the block in the bag for the entire duration of the growing cycle. However, there are some exceptions.

⮕ Shiitake should be removed from the bag before going into the fruiting chamber.

⮕ Nameko should have most of the top of the bag cut off (leaving about 4" of plastic above the block) before going into the fruiting chamber.

Our fruiting block kits are made from sawdust blocks that have been amended with substrate supplements.

We love our mushrooms!

We have been very happy with the mushrooms. We have been getting from you guys. Usually, we at two batches out of each block. My favorite is the trumpets.

Thanks for the great review, Karen! We're so happy you're enjoying the experience.

Outstanding!

I’m fairly new to the myco world as far as growing goes. Everything I’ve gotten from North Spore has produced beyond expectations. The online support and information is incredible! Customer service from this group is untouchable. Gave 5 stars because 10 isn’t an option! Thanks to North Spore team for an amazing start to my mycology future! Curt

Happy with the Lion Oyster Shiitake Blocks

Overall experience was very good, The Lions Mane had enormous fruiting, and is just now starting it's second. I dried and made powder for tea/coffee. The Oysters were the same, prolific first fruiting, and now on their second, although not as much. I made large batch of schroom soup and dried a bunch. The Shiiakes have not been as cooperative, first fruiting was small, I may have let it dry out too much (didnt have humidity chamber yet) or unwrapped to soon. Ive "reset" the block, and its in the chamber again, hopefully it'll go... over all happy with the results. It's a good hobby, with yummy results!

I want to entend my Mushroom cultivation gradually, but seeing these blocks of mushrooms and how they develop is step one. I get wonderful flushes from these and my cuisine now features a much greater variety of fungi!

We're so happy to hear you're enjoying the experience, Christine! Our team is here to help if you ever need anything.

Love these mushroom blocks. They fruit quickly. Once I harvest them, I put them back in the fridge for 48 hours and then they fruit again. Great product and great company. If I have any questions, they always respond.

Thanks for the great review, Colleen! Please reach out if you ever need anything.

Highly recommend this to anyone starting out. I used this subscription for almost a year and it was perfect for developing my skills with many different types of mushrooms, to prepare me for more difficult projects.

Impressed

I was not able to get my Fruiting Blocks into my Boomer II for a couple of months, so I placed them in the fridge.
I took my Lions Mane, Italian Oyster, and Shiitake blocks from the fridge and performed the normal preps, as described by NorthSpore helpful links and videos. Into the BoomRoom they went on March 6, the Shiitake block went in the next day after a spank, de-bagged, and a long cold water soak.
March 8, the Oyster block was pinning and the Shiitake was changing.
March 12, the Oyster block and Shiitake are in full development.
The Lions Mane is slower to develop, but small heads are showing.
Thank you North Spore, so exciting.

Thanks for the great review! We're so happy you're enjoying the experience.

Awesome subscription of Shrooms

I just received my boxes. I ordered the beginner and intermediate sub boxes to arrive monthly. Want to keep my new North Spore Boom Room filled to the gills with shroomage
This will hone my skills with the variety they send each month
Definitely recommend!

Thanks so much, Jeremiah! If you need help with anything, please reach out.

Only good things

The blocks and the boom room are great. User error has defined my experience so far. I have gotten 3 golden enokis in a row, so the boxes could use some variety from my perspective solely. Im probably going to reduce my subscription in the new year because I don't want the room too crowded. But Im looking forward to stashing the used boxes in the garden and around the house. We really like all the stuff we've got from North Spore. You're always the first name when we talk about our mushroom gardens. We will always be coming to NS. Im real excited about HB4, too. Keep it up. You guys are great. Im sure you guys sell merchandise, but I never get past the mushrooms before I spend more than I want to. Thanks a lot

BlockBox Subscription

I love the beginner BlockBox subscription. For me, it’s “set it and forget it” needing little maintenance. It only requires looking in on my monotub once daily to ensure the humidifier is full to see what’s growing! I have had very good results with the fruiting blocks often getting 2-3 flushes per block. With the subscription I can control the shipping dates to work for my schedule.

Only one lions Maine did well. Other two did not do well. Not sure if we will continue. I am sure what we did wrong. I do not recommend because of cost. 1 out of 3 success rate not good.

Mushrooms

I've had a great experience using North Spore's products. I was successfully able to cultivate Shiitake and Lion’s Mane mushrooms, and I'm now starting to see Chestnut mushrooms begin to fruit. The Lion’s Mane and Shiitake are already on their second round of fruiting, which is really exciting. The process has been rewarding and the results have exceeded my expectations.

Thank you so much for sharing your experience along with some photos, Charles! Congrats on your awesome harvest.

Blocks box

I received a boom room for Christmas so subscribed to the block box. All have grown. The pink oysters were gorgeous. The lions mane I am on my 4 th flush and the 3rd was the biggest flush. I had a good initial flush from the snow oyster and a small 2nd, same with the blue. Without the Boom room I was unable to grow counter top boxes as it’s so dry here. The boom room is great for growing.
Recommend the block box as a first step to growing your own. You get 3 varieties in each so a good way to try different mushrooms.

Thanks for sharing, Trudy! Your pink oysters and lion's mane look amazing. Please reach out if you ever need anything!
