## 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
