Using a Spray and Grow Kit

Product Details

Why We Love Them:

Blue oyster mushrooms are velvety, savory, and mild and pair perfectly with just about any recipe! Blue oysters are a staple here at North Spore (going all the way back to when we began as an urban farm.) After perfecting our blue oyster kits over the years, they’ve become one of the easiest kits to get multiple fruitings from and should produce a second flush of mushrooms (or more!)

100% Guaranteed.

Our blue oyster mushroom kits are reliable producers and tend to yield large flushes of beautiful light grayish-brown to deep blue-gray mushrooms when given adequate humidity. With continued proper care, you should be able to get multiple flushes. We 100% guarantee your first flush of mushrooms, but hope you'll try for 2 or 3!

It's Mycelium!

Your kit includes an amended sawdust block fully colonized with mushroom mycelium. It may appear covered with a soft, white substance - that's the mushroom mycelium! It is completely normal and means your kit is packed with fungi ready to fruit. The mycelium of some species is more prominent than others.

Classroom Logistics

Planning for Your Classroom

  • Group size: Each kit works well for a small group (4-6 students) observing and recording growth together, or as a single teacher-led demonstration kit for whole-class observation
  • Time commitment: Daily spraying takes under a minute; mushrooms typically appear within 7-10 days, making this a good fit for a 2-week unit with a quick daily check-in
  • Classroom fit: Pairs naturally with units on decomposers, fungal biology, or ecosystems. No lab space or special ventilation required, just a stable spot out of direct sunlight
  • Safety: Kits are safe for students to handle and observe under normal supervision; no chemicals or hazardous materials involved
  • Curriculum included: Every kit comes with a free NGSS-aligned guide mapped to your grade band

NGSS Performance Expectation Codes:

  • K-2: K-LS1-1, 2-LS4-1 
  • 3-5: 3-LS1-1, 5-LS2-1
  • 6-8: MS-LS1-1, MS-LS1-2, MS-LS1-5, MS-LS1-6, MS-LS2-1, MS-LS2-3, MS-LS2-4

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.
