Review: Ecellent quality! - Excellent quality. Though, reading the packaging packet, Made in China, means it was sent to the U.S.A. and then sent to the U.K. Not really helping the planet! Happy with the product but not happy with my choice after finding that out on receipt of it.
Review: 50/50 - Used 7. Had two fail almost immediately. They’re okay. Factor in your potential losses. You bet what you pay for i guess.

## Questions & Answers

**Q: Why are all these rookies not capable of understanding that this product is for bags and not a grow kit?**
A: The description was misleading it says it’s a kit with the oyster mushrooms and growing medium. You need to change the description and you shouldn’t be hateful to legitimate customers.

**Q: How do you inoculate if there is no self healing port**
A: You install your own port with thermal(hi temp) silicone sealant or... don't seal the bags just use tyvek as filter and fold over a few times.

**Q: Do I need 8" or 12" impulse sealer to seal those bags?**
A: I use a 12" sealer. The bags are exactly 8", my concern was;  will i get a tight seal on the ends of the 8" sealer? I'm Still Not sure so i want big.

**Q: Is there a video on how to use these?**
A: Look on YouTube, that’s what I did
