Features 6

  • GROW IN THE BAG FROM INOCULATION TO HARVEST: ShroomTek is an all-in-one mushroom grow bag with everything your dung-loving mushrooms need built in sterilized substrate, self-healing injection port, and filter patch; just add a spore syringe or liquid culture and the entire grow happens inside
  • INCLUDED SPORE BOOSTR ACCELERATES YOUR GROW: Each bag comes with 5ml Spore Boostr, a nutrient-rich broth that converts slow-starting spores into vigorous liquid culture in 1-2 weeks so your mycelium colonizes faster and your first flush arrives sooner
  • MYCOLOGIST-FORMULATED PROPRIETARY SUBSTRATE BLEND: ShroomTek's sterilized mushroom substrate combines organic manure-based compost, organic grain, coco coir, and hand-selected supplements optimally hydrated and balanced for strong mycelial growth and a healthy first flush within 30-60 days
  • SELF-HEALING INJECTION PORT AND 5-MICRON FILTER PATCH: The self-healing port accepts a spore or liquid culture syringe for clean, needle-guided inoculation; the 5-micron filter patch blocks airborne contaminants while maintaining steady gas exchange throughout colonization

Description

North Spore was launched in 2014 by a mycologist, an organic farmer, and a photojournalist -- three college friends brought together through their shared love of the mycological world. North Spore provides everything one needs to grow mushrooms, from the beginner to the expert. From Spray & Grow Kits to growing chambers, sterile substrates, lab supplies, and more. We also offer medicinals made with the highest quality fruiting body extracts. Our beginner-friendly ShroomTek All-In-One Mushroom Grow Bag was formulated by mycologists to simplify mushroom growing while maximizing the speed and size of your grow. (All that's required is a spore syringe or liquid culture!) Our beginner-friendly ShroomTek All-In-One Mushroom Grow Bag was formulated by mycologists to simplify mushroom growing while maximizing the speed and size of your grow. (All that's required is a spore syringe or liquid culture!) The entire grow takes place inside the bag – from inoculation to colonization to flush – making the entire process both seamless and effortless! Before inoculating your ShroomTek bag, inject some of your spores into Spore Boostr , draw the Spore Boostr liquid back into your syringe , and allow them to germinate. After 1-2 weeks, when you see visible mycelium, it’s time to inject! Spore Booster is the newest addition to the ShroomTek family, and it's designed to to increase the speed of your grow by germinating spores in your syringe, creating a faster growing "liquid culture". Spore Booster also allows you to catch contamination before you inject! Learn how to use it and achieve your best grow in this video! The entire grow takes place inside the bag – from inoculation to colonization to flush – making the entire process both seamless and effortless. Made with a proprietary blend of sterilized, nutrient-rich, manure-based compost, organic grain, coco coir, and quality substrate supplements. Each bag is optimally hydrated for substrate mix and volume to ensure a healthy, well-hydrated environment for optimal mycelial growth. Bags are sterilized in a commercial-grade autoclave. Sterility is verified using biological indicators and temperature sensors. How soon can I expect my bag to start pinning? Depending on the mushroom species and strain, it will take about 25-30 days before pins form. Can Shroomtek be used by beginners? Yes, ShroomTek is easy to use and requires minimal maintenance. However, it is important to read through all of the instructions before you begin to gain a better understanding of the entire process from inoculation to fruiting. How should I store my bag while it's colonizing? Allow your bag to colonize undisturbed and out of direct sunlight. Temperature for incubation shouldn't exceed 75 degrees F or dip below 55 degrees F. Keeping your bag at the higher end of the temperature range will encourage faster colonization. How can I speed up colonization? When the mycelium has grown 3-4 inches outward from the point of injection, carefully massage the bag to break up the colonized substrate and mix it into the uncolonized substrate. IMPORTANT: Do this without opening the bag. Do I need any special equipment or supplies to use Shroomtek? When you inoculate your bag, you will need a spore syringe or liquid culture, a pair of latex or nitrile gloves, a spray bottle with 70% isopropyl alcohol, and paper towels. Later in the process, you will also need scissors and an XL rubber band.

Phenomenal instructions and guaranteed success!
Item Package Quantity: 1
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. ... show more

My number one go-to for quality mushroom cultivation equipment
Item Package Quantity: 1
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. ... show more

Contamination Twice!
Item Package Quantity: 1
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.

Always reliable.
Item Package Quantity: 1
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. ... show more

Not bad.... I like them. Even with some trouble.
Item Package Quantity: 4
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. ... show more
