North Spore 'ShroomTek' + Spore Boostr All-in-One Mushroom Grow Bag | Grow Dung-Loving Mushrooms Like Magic Right in The Bag | Just Add Your Own Spores | Made by Mycologists

I have used these for 3+ years. Never a contam problem -- EVER. For you growers of dung loving species, I used to grow in bins but faced contamination in about 50% of grows. These pretty much solve that, so I find it more economical to get consistent flushes from smaller bags than contaminated grows in larger ones.

Best AIO bag out there...IMO.. Every one I've used so far has good growth and no contamination!

I didn't actually get around to using this grow bag right away, but even with the delay, it worked perfectly! The instructions included are incredibly thorough and foolproof. They ensure that no matter what medium you choose to start with, you'll get highly successful growth and delivery. A wonderful all-in-one kit for both beginners and experienced growers.

This brand never disappoints. Great quality, reliable, every time. I didn’t use the spore booster, never really needed to. I just poured some colonized grain into this bag this past week and already I have about 40% colonization. I’ve never had a contamination issue with this product, and I trust them implicitly. Price wise, they’re a little higher than some, but absolutely worth it for the piece of mind.

Gonna stick to my other brand (BA) this one just wasn’t growing at all, despite all sorts of troubleshooting, I think this can work for regular mushrooms but some species cannot thrive in this bag
