Frequently Asked Questions

Inside your Spray & Grow Kit is a living organism, so we recommend activating it upon receipt. If you need to wait, they can be refrigerated for up to 6 months. 

It's important to get the area where you cut open the bag nice and damp! Try 5-10 sprays each time. If the surface of the block seems very dry the next time you spray it, you should give it a bit more water or water a bit more often. If you run AC or live in an arid climate, using a humidity tent can be useful to prevent your block from drying out.

We guarantee at least one fruiting of mushrooms off your kit, but it is possible to have multiple fruitings with care and patience. In terms of yield, you can usually expect your first flush to be somewhere in the range of 1/2 of a pound to 2 lbs. Each subsequent fruiting will likely be smaller as the fungi use up nutrients in the substrate.

The word fruit can be very specific, referring to foods like berries and apples, or a bit more general to refer to how an organism reproduces. So tomatoes and rosehips are the fruits of those plants; they contain the seeds. Mushrooms are the fruits of a fungus; they contain spores. So when a fungus starts to produce mushrooms, we call that fruiting.

Hold the cluster near the base and spin them. If you'd rather use a knife and cut them, that's fine too! Clean off any loose bits from the kit before continuing to spray and cut off any bits of sawdust from the block on your mushrooms before cooking and eating them.

After removing the front panel of the box along the perforated lines, cut an X into the exposed plastic. Remember to leave the plastic flaps of the X on the bag, they'll help to keep moisture in. The mushrooms will easily grow out of the sliced X section, so no need to open it up more as they fruit.

Absolutely! Mushroom cultivation is a great activity to do with the whole family, whether you'd like to grow indoors or outdoors. If you're new to mushrooms, we recommend starting with a Spray & Grow Kit or a Plant & Grow Kit – both make it easy to grow fresh, organic mushrooms at home.

We want you to have the best possible experience with every North Spore product and guarantee free replacements within 30 days of receipt for any damaged, contaminated, or unusable product.

We recommend absolute beginners start with our Spray & Grow Kits, which make growing mushrooms at home super easy.

Success in buckets

It was so cool. After purchasing golden oyster, I decided to try a bucket method. I used the spray kit to inoculate the straw I the buckets. It took some time, but it worked! I love your company and thank you so much.

Wow, thanks for the awesome review, Amanda! Great harvest.

The gift that keeps on giving!

I was successful in my first crop of golden shiitake mushrooms in the box but I am so happy that I then planted the contents of the box into a planter on my covered screened porch and they are just now pinning there. Gee, maybe I’ll have my own mushroom farm. I would submit pictures but I don’t see how to do that. I live in Florida and I am hoping for great things since our weather will favor the mushroom growth year round. My purchase was so worth it.

Hello Virginia!

Thank you so much for taking the time to leave a review! Your photos of the mushroom pins look great, congrats on your Golden Oyster success! We appreciate your support and will be here for all of your mushroom needs.

Sat around for 6 months before use but still grew!

So amazing and fast! Have bought many products in the past for outdoor grows but never for indoor. Grew super fast even after I forgot it for 6 months it busted thru the bag and began to grow in dormancy when I finally opened it and I thought it was trash but look at it now! It chose life! First flush, hopefully one or 2 more.

Awesome flush, Aleks! Thanks so much for sharing.

good, once I got the hang of it.

The first flush didn't last long: too many leprechauns nibbling when I wasn't looking

Haha, thanks for the mystical little review, Christopher. The mushrooms really do grow quickly once they start. Don't hesitate to reach out to our customer service team if you ever need anything!

First flush finished

I received this kit for Father's Day as my wife knew I've been interested in growing these for a long time. I've been a fan of North Spore's YouTube channel for some time so it was fun to finally have the kit here in person. The packaging, presentation and instructions are really well done. The daily maintenance is simple and it's a nice ritual to check in a few times a day and see how it's going.

Unfortunately, my first flush was nowhere near the size I see in pics or other reviews. I would estimate it was about 20% of what others are getting. We were able to get 1 very small side dish for dinner out of it. On the bright side, it was delicious! We followed the recipe they recommend, with butter, garlic, rosemary and thyme.

I would have really liked to have a bigger yield to try some other recipes. I don't know if it was my growing conditions or if I did something wrong. Hopefully there's a second, bigger flush coming! 🤞

Loved it!

Worked like it was supposed to and I just cut my second bloom. The first was about 1.2 lbs and the second was a bit less. I cooked the first bloom with some garlic and onion and served it with a hunk of beef. Magnafique! I'm getting ready to order a second kit.

Your grow looks amazing, Bill. We’re so glad everything is working out for you. Hope the mushrooms were delicious.

These are so easy and fun.

All these grow kits are a great way to get started in the hobby. Do yourself a favor and grab one (or a few) and get started. This is the best way to get your foot in the door of an amazing hobby. And, if you decide to keep going within your mycological journey, this is a simple way to grow a few and then let a couple go to spore for collection for later.

Thanks so much, Chad! We're so happy you're enjoying the experience.

This kit is golden

I received this kit as a gift. Put it next to the kitchen sink as suggested. Spritzed everyday and in less than a week it exploded with golden oyster mushrooms. Will harvest and let it grow again. Good science lesson for homeschoolers. Would highly recommend.

Your grow looks amazing, Laura! We’re so glad everything is working out for you. Please reach out if you ever need anything.

I love this kit!

This kit is great. It was easy to start, began growing in about a week, and it's fun to watch. I don't think it will be long until I cut it, and eat it. Thank you!

Your golden oysters look amazing, Laura! Thanks for the great review.

So pretty, and huge!

I love this kit. It took several weeks for it to decide to do something, but then it didn’t waste any time at all. Within a week I have a huge flush that I plan on harvesting some of it today and cooking for the football party we’re having today to watch the Arizona State game. There are so many small pins throughout and underneath that I decided to try to just cut off the mature ones and see if the others will continue to grow. That’s one of the fun things. I love about these kits, you can experiment a little bit. It was so much fun to watch a teeny tiny little nubbin, like the size of the head of a pin grow into this big beautiful cluster in a week. I swear every time I walked past it, it was bigger. So much fun. Can’t wait to taste it.

Wow Pat! Seems like you are on a roll! Thank you so much for sharing your incredible grows with us. We love to hear about how our customers are using our products, and sharing the love. Keep spreading those spores!

Amazing grower!

This kit, although they’ve all been great, is by far my favorite. I started seeing pins the day after I scored the Plastic and misted it. Within a week they were huge and ready to be harvested. I cooked them up with a little smoked paprika and served them with Christmas dinner. They tasted very much like bacon and everybody loved them. I soaked the block in water, let it drain and set it out and in less than a week, I have got more pins that I could possibly count. What an impressive producer and so delicious! If you wanna try a prolific and delicious mushroom for your first time, go with this one! I’m including a picture of my first harvest, and the new pins that have popped up, again in less than a week! Very impressive!

Thanks so much for these kind words, Pat! Love to hear about your positive growing experience!

Golden Oyster spray n grow

Excellent. Shipped to FL as a gift for my 11 year old mushroom loving granddaughter. The kit grew as promised and has amazed her and her family. She made mushroom scrambled eggs.
Thanks for a great product!

Love to hear it Elizabeth. They really do make amazing gifts, and are so fun to watch grow. So happy to hear your granddaughter is enjoying her mushroom kit!

Philip

They shipped fast. Upon receiving it I examined the package by opening it and removing the substrate. The ‘cake’ was NOT fully colonized. I contacted them and they said that it might look less than optimal, I should be patient and it would produce mushrooms.

While allowing the bag to sit and reacclimatize to my home due to shipping movement I noticed mold development. I contacted them again but so far haven’t received a response. We shall see how it goes once I get a reply.

We appreciate the honest review, Philip! I hope your replacement performs better. Don't hesitate to reach out to customer service if anything else comes up.

Easy to care for and fast. I'm already getting a second flush. We sauted them and ate them with steak.

Thanks for your kind review Tim! Golden oysters are one of our favorite species, too! Glad you’re enjoying them!

FRUITFULLY FUN & EASY!

I absolutely love North spore and this is one of the first spray and grill kits I purchased. Perfect for a beginner easy to follow instructions and multiple fruiting's. I did not use any type of humidity tent I just had the boxes on the table as you can see in the picture although this is in my large laundry room so there is some humidity present. Back to purchase another. Highly highly highly recommend I have sent them as gifts and everyone has been so excited and pleased with their spray and Grow boxes. I will add that the yellow oysters are also probably the best regarding the amount of harvest and also the amount of recruiting's out of the block so it is one of my favorites.

Thanks, Kat! Golden Oysters are one of our favorite species, too! Glad you’re enjoying them.
