ShroomTek All-in-One Mushroom Grow Bag, 4-Pack | with Spore Boostr Liquid Culture Accelerator for Dung-loving Mushrooms, Mycologists-made, Beginner-friendly, Just Add Spores

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.

This looked very promising since I wanted to try another way to grow mushrooms. Unfortunately when I tried to inject my spores directly into the bag, nothing grew, besides mold. I used other products with my spores, and I didn't have mold or contamination.

Great shroom tech from Shroomtek. 100% am buying from this company again I’ve tried others and these guys are still the best. Great value for the price and great return for my investment.

This is a solid product overall. Unfortunately, 2 of the 4 bags I received ended up contaminated. That said, North Spore was quick to offer replacements, and their customer service alone is the reason I’m still giving this a strong review. I do larger bulk grows, and compared to traditional all-in-one bags, this design is actually much better. These bags colonize cleaner and faster in my experience, and the format makes them easier to work with than many standard AIO bags. The batch I received did seem a bit wet, which may have been due to shipping is such cold weather when they were received, which likely contributed to the contamination in two bags. I verified my liquid culture on agar beforehand, so I’m confident the issue was with the grain rather than my inoculant. That said, contamination can happen with any grow product, and it’s part of the learning process when trying new tek. Overall, I’m impressed with the design and performance of the bags that worked. North Spore is also sending two replacements, which shows they stand behind their products. I’m happy to give them another shot.

Great results as long as you follow the very helpful and comprehensive instructions. You will need to get your own spores for whatever type of mushrooms you wish to grow, be it Morels, Truffles, (good luck finding those spores!), or one of the many "Magical" varieties. Great size for the beginner, (that would be me). I had great success first time I tried growing my own and I am not a master gardener by any definition of the word.
