Organic Pink Oyster ‘Spray & Grow’ Mushroom Growing Kit

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.
