Blue Oyster Spray and Grow Mushroom Kit

Organic Blue Oyster Spray and Grow Mushroom Fruiting Kits from North Spore.  

About the kit:

USDA-certified organic 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!)

That's not mold, it's mycelium!

Your kit includes an amended sawdust block fully colonized with mushroom mycelium. It may appear covered with a soft, white, mold-like substance - that's the mushroom mycelium! It is completely normal. The mycelium of some species is more prominent than others.

Growing Instructions 

1) Inside this box is an amended sawdust block that has been completely colonized by mushroom mycelium. Open the front of your kit along the perforated line and dispose of the remaining cardboard.

2) Slice an 'X' into the plastic underneath with a sharp knife or scissors.

3) Lift open the top of your box to find the sprayer and instruction booklet. Fill the sprayer with tap water and generously spritz the plastic where you sliced your 'X' shape. Spritz your kit at least twice daily - more if you're in a particularly dry climate. (If your mushrooms start to grow but dry up and die, your growing conditions may be too dry and you should make a humidity tent!)

4) Place your kit in the most humid part of your home and outside of direct sunlight. We suggest putting it on a kitchen counter close to a sink. The mushroom mycelium will sense the oxygen in the air and produce mushroom 'pins,' another term for 'baby mushrooms.' 

5) It usually takes 5-14 days for pins to form. Once pins begin to form, mushrooms will grow quickly. So when you spot your first pins keep an eye on them. The warmer the environment the faster they will grow. Mushrooms should be ready to harvest 2-5 days after pin formation.
