Hey - I'm Tom, the creator, builder, and owner of the Oak and Spore mushroom farm. 

I've built two highly profitable mushroom farms. The first in my 2-car garage at our residential property, and the second, a purpose built facility on a 4 hectare block of land tucked into the Canterbury countryside.

I've learnt a lot about farming mushrooms, lessons I can teach you!

We went from a 2-car garage from producing $100k+ to a small commercial farm producing $250k+.

Our financial goal for 2023 is $400k+!

A message from our farm to yours 

The Oak and Spore mushroom farm has been operating since 2018, and we have learnt a lot on that time. Not only that, but we have grown each quarter since the start.

We have put this course together to help people who want to start their own farm, and want to see what we do on ours. It's not rocket science, it's simply growing and selling mushrooms. But each mistake you make is going to cost money, time, and will edge your farm closer to failure. Prevent failure from happening by learning by someone who's been there before. 

I have made the mistakes, and so I hope you don't have to make those same mistakes.

- Tom Brain
