Clean products are what we specialise in, it’s our bread and butter – and we’re good at it. We have to be.
Sterile technique is like driving – you can’t learn it by reading, you need to be practising it always.
While most contamination reports are statistically more likely to be down to beginner error, it’s not always the case.
Sometimes it may actually be us. Does that mean we don’t know what we are doing or that we’re rookies at this?
No. And here’s why.
We regularly purchase live gourmet mother spawn from one of, if not the largest, most accredited mycology business in the world.
This company is BIG and they even run week-long training courses in mycology and have the most incredible set up worth a fortune.
Even they make mistakes. We’ve had to get in touch with them a couple of times after receiving contaminated spawn.
The point we’re trying to make here is that even the masters of mycology mess up. Nature is unpredictable and we all make mistakes.
Although we don’t offer refunds on our products, we will send a voucher for it’s replacement.
Irregardless who is at fault.
A second chance on us 🙂

For spawn these filters perfect.
For FAE in say your own monotub builds etc, I’d say use polyfill over SFD’s or micropore as it puts a lot more FAE through it which is what you want.
are these used with the regular screw ring on a mason jar whilst pressure cooking grain for g2g?

However, we prefer to also use the metal lid with a drill hole in the centre.
