Review: Great product - Heard about this from a friend and wanted to try. Arrived very fast. Looks like it was made very well. Sturdy plastic just like the Uncle Ben ones, except this one is all see through which is why I bought it. Would be good to check on mycelium growing. Rice: looks well hydrated, but excess water!! Great! I know Uncle Ben’s had some formula change where there’s too much water lately. Been exclusively using Uncle Ben’s Tek following 90sec mycology tutorials with success. Crossing fingers that this one is even better.
Review: Nothing, absolutely nothing grows. - Absolutely a scam. I’ve had better luck on white label uncle Ben’s from grocers. At no point should anyone buy these for mycology. cordyceps, oysters, and reishi did not propagate…. They won’t even grow bacteria…. Been over 40 days watching to see if any of those three liquid cultures would start to grow….. nothing. Tossing this one up to citizen science. Don’t do it LOL

## Features

- UPGRADED UNC BEN’S TEK: Built for mushroom growers—clear pouch for monitoring, 50% more grain (0.8 lbs/bag), extra headspace for easy shake n’ break, and less water to cut down pooling
- RAPID COLONIZATION: Smaller grain size and higher starch mean faster mycelium growth than rye, millet, wheat, or typical all-in-one grow bags—colonizes quick and clean
- FULLY SEALED: Sealed tight to stay sterile—no filter patch means no risk of outside particles sneaking in during shipping or storage like with microfilter spawn bags
- CONTAM-RESISTANT: Infused with rice bran oil to boost resistance and performance—better antioxidant protection, stronger mycelium, and easy grain separation built in
- VERSATILE & EASY TO USE: Works great with spore syringes, LC, agar, or G2G. Beginner-friendly, grow-tested, and designed for high yields with low hassle

## Questions & Answers

**Q: How does Benny Boy's Tek compare to larger mushroom grow bags?**
A: Benny Boy's Tek lets you grow up to 6 different strains at once, giving you more variety and flexibility. With larger bags, you're limited to just one strain, and if something goes wrong, the entire batch could be affected.

**Q: Will Benny Boy's Tek colonize faster than other options?**
A: Yes! Our smaller, nutrient-rich bags are designed for quicker colonization and faster harvests. Larger bags take longer to fully colonize, which can delay your growing process.

**Q: Why doesn’t Benny Boy's Tek have built-in filters?**
A: Our fully sealed design locks in freshness and creates a more controlled environment improving long-term reliability. Bags with built-in filters can introduce unnecessary exposure over time.

**Q: I inoculated the bag but nothing grew. What happened?**
A: If no growth occurred, it’s usually related to insufficient gas exchange or issues with the liquid culture or spores used. Without proper gas exchange, growth can stall or stop altogether. Feel free to reach out if you need any help.

**Q: Why do I need to add gas exchange to the bag after inoculation?**
A: Mycelium produces CO₂ as it grows. Without a way for that CO₂ to escape, the environment inside the bag becomes stale, overly wet, and can stall colonization or lead to contams.

### ⭐⭐⭐⭐ They are good for beginners and mycologists that just want to size down
*by R***S on August 16, 2025*

I ordered these because I was tired of buying all in one bags so I wanted to give S2B a shot. So far these bags are amazing, they colonize pretty fast too and it’s good for shoe box grows with a ratio of 1:1 and it will be perfect. Im definitely going to buy some more. But I will say they’re a little too pricey for 6 bags tho.
