 Grow the spawn of you choosing with our sterile, ready prepared spawn. This spawn hasn't been inoculated, so you can add your own mycelium to it and grow the spawn of your choosing. 

Our spawn is made in house, often using culture lines we breed ourselves. We use correctly hydrated wheat grain, with no wood additives.

Our sterile grain comes in 2kg (approx) bags, and is approximately enough to inoculate 10-20 mushroom growing blocks one colonised.

Oak & Spore sterile grain is made especially for mushroom growing enthusiasts, and beginners alike. It will be contamination free, and ready to use. 


  • Strain: none

  • Inoculation requirements: 1-2ml liquid culture or small cutting from petri dish

We ship all items as fast as we can. Some products might incur a slight delay as we ensure the mycelium is happy, healthy, and fully colonized.


Are these kits easy to grow?

Yes! All the hard work has been done. The mycelium is fully colonised, and they are ready to grow some tasty mushrooms!

How long do they take to grow?

Generally between 1-2 weeks to get your first crop. They grow very quickly!

How many crops (flushes) will I get?

Generally one or two flushes from a boxed farm, two or three from a commercial farm. There is about a 1-2 week rest period between flushes where the mycelium will just sit and relax for a bit.

Do I need a dark area?

No! Oyster mushrooms actually like some indirect sunlight. So nearby a window is fine, as long as the sun doesn't beam onto them.

Where can I grow them?

The bathroom or kitchen is a great spot for a few reasons. You are often in these areas, so it reminds you to spray them with water. Mushrooms like fresh air, and you often have a window slightly ajar. Mushrooms like indirect light, and these areas often get some sun. And finally, these areas have easy-to-clean surfaces, so you can wipe away any spores.

Is it OK to grow mushrooms inside?

Growing some mushrooms to eat in your kitchen, bathroom, or laundry is fine. They will drop some spores if allowed to overgrow, but these can be wiped up with realtive ease.
