Grow it, then cook it

Better than anything from the grocery store.

Blue Oyster is meaty and savory. Tear it into strips and sear it hot in butter or olive oil until the edges turn golden and crisp. It soaks up garlic, soy, and herbs beautifully.

Toss them into pasta, load them into tacos, layer them on toast. The grow guide inside your BloomBox includes our favorite recipes.

Super easy, kid friendly growing process, would 100% buy again!

This grow kit was amazing! I bought it for my son’s birthday because he’s very into nature and growing things. The process to start it was easy and needed minimal help from an adult. […] My son wanted to try the mushrooms right away upon harvest, so we pan fried some in butter and topped a bowl of ramen with them. They were extremely tender and flavorful!

SO FUN

To say this was fun for not only me, but my kids as well, is an understatement. This kit was worth every penny. We were so excited to learn more about how mushrooms grow and watch them start to develop and then grow to beautiful mushrooms! I was the only one who wanted to eat them but that was ok with me!

Fungi Feeling Fabulous

Received mushroom block, a little odd looking, I reached out to them and they got back to me super fast. They assured me that the mycelium is alive and gave me 2 different ways to proceed. I chose the recommended way, I need to wait a few days. So for now I'll post pictures of the block and once grown I'll post my harvest. I'm very impressed with the size of the block the health of the block and the accessories with directions that were all included. Great customer service. I'm sure I'll be a repeat customer. I have to add to this review---- I am so impressed by this company!!! The mycelium is so healthy and strong. I have tried 2 other companies and they don't compare to the quality that I have received from Nublume. High quality! Highly recommended!!!

Fun and easy set up!

This product is so nice for firat time mushroom growers! I love gardening and love cooking with mushrooms so I wanted to try growing my own. My kids (6&4) were so excited to see mushrooms grow that they set up the box with very little help from me. So easy, simple and so excited to try the end product. Will definitely be getting g more as my kids already want to set up more boxes!

NUBLUME BLOOMBOX ROCKS!

I bought the NuBlume Blue Oyster Mushroom BloomBox as a first time mushroom grower. It arrived the next day just as it said it would. The packaging is modern and attractive with an immense amount of pertinent information such as USA made, 1% to the planet reinvestment, details on the mushroom being grown, USDA organic, instructions for growing g, and a QR for all the information printed right on the attractive packaging. As far as the 1st grow went I purchased the Blue Oyster Mushroom Box. It said expect pinning by the 5th-7th day. Here on the Galveston-Houston gulf coast I had pinning by day 2. I am literally sitting here on day 3 watching the fruiting develop right before my eyes! I am loving my first attempt at growing mushrooms. NuBlume has made it fast, simple, fun, attractive, informative, and the experience exceeded my expectations. The box says flip over for the second grow! I will post if my experience changes after grow #2. But I don't think it will. Well done NuBlume!

Love it! Made delicious soup!

Follow directions. Delicious! Can get a second bloom sometimes. Used ghee, avocado oil, sautéed chopped mushrooms then added a little cider vinegar (stirred), then semolina flour, white pepper, onion, garlic, and pink salt, sautéed longer then added milk.

Highly recommended!

FAQ

Got questions?

How is BloomBox different from ShroomBloom?

BloomBox arrives pre-inoculated and ready to fruit, so there is nothing to inject and no culture to buy. Cut, spray, and harvest. ShroomBloom is an inject-and-grow kit for growers who want to choose their own culture.

Can I mix varieties?

Yes. Every BloomBox is $24.99, and any mix counts: add 2 or 3 kits of any varieties and save 10% on each, or 4 or more and save 20% on each. Use Build your pack on any BloomBox page; kits already in your cart count too. The discount applies automatically at checkout. ShroomBloom has its own bulk pricing and does not combine with BloomBox tiers.

Which variety should I choose?

Lion's Mane crisps up smoky and savory. Blue Oyster is meaty and mild. Pink Oyster is bold, colorful, and fries up crispy. Can't decide? Mix all three.

How fast will I see mushrooms?

Tiny pins begin forming within days of cutting your X, and most kits are ready to harvest in about 7 days.

How much will I harvest?

Up to 1 lb+ of fresh mushrooms from one box, across 2 to 3 flushes. After your first flush, soak the block in cold water for 4 to 8 hours and keep misting for the next one.

How much time does it take each day?

About 10 seconds, twice a day. Mist the exposed grow block with the included spray bottle and that is it.

How long can I store the kit before starting?

It keeps 3+ months on a shelf and 6 to 8 months in the refrigerator. For the best results, start it while it is fresh.

What does the guarantee cover?

Guaranteed to grow or we replace it. Didn't grow? We send a new one free. That covers mold, contamination, or no growth on kits started within 3 months of delivery. After 3 months we'll still send a replacement; we just ask you to cover shipping.

Who answers my questions?

Our team of mycologists. Reach out any time and we will guide you through every flush.

Do I need any special equipment?

No special equipment needed. The grow box, spray bottle, humidity tent, humidity bowls, bag sealers, and grow guide are all included. You just need water and a knife or scissors to score the X.

How fast does it ship?

Most orders ship in 1 to 2 business days. Orders of $59 or more ship free.

Want to choose your own culture?

Inject your own gourmet culture into a pre-sterilized all-in-one bag. 2LB and 4LB kits.
