As easy as inject, grow, harvest

ShroomTek contains a proprietary blend of sterilized, nutrient-rich, organic manure-based compost, organic grain, coco coir, and several quality substrate supplements (although we keep the exact blend a secret!) Each bag is optimally hydrated for substrate mix and volume to ensure a healthy, well-hydrated environment for optimal mycelial growth.

Bags also include a self-healing injection port for use with a spore or culture syringe plus a 5 micron filter patch to block airborne contaminants while providing even gas exchange. Once inoculated, you can expect your first flush within 30-60 days (depending on species and strain.)

Spore Boostr

Speed up your grow with Spore Boostr!

Each ShroomTek includes Spore Boostr (5 ml), a nutrient-rich broth that turns slow-growing spores into fast-growing liquid culture. Before inoculating your ShroomTek bag, simply inject some of your spores into Spore Boostr and 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!

Inoculation ratio

We recommend using 2.5-5ccs of your favorite spore syringe or liquid culture syringe. (Higher inoculation rates may improve colonization times and mitigate contamination.)

Storage

ShroomTek All-In-One Mushroom Grow Bags should be stored at room temperature out of direct sunlight. No refrigeration is necessary. They can also be stored for several months before use.

Best Practices

We always recommend clean hands and latex or nitrile gloves to reduce the introduction of contaminants.

It is best practice to wait a minimum of 1 week after arrival before injecting all-in-one grow bags to ensure they were not compromised during transit. Rest assured that your purchase is 100% guaranteed. If your bag was compromised, we will replace it.

More ways to grow

Although the ShroomTek All-In-One Mushroom Grow Bag is designed as a self-contained growing chamber, it can be used in conjunction with other growing chambers such as a monotub or BoomRoom martha tent, should you want fuller control over environmental conditions.

Important Info

⚠️ IMPORTANT: Spore syringe vs. liquid culture syringe

The ShroomTek grow bag works with both spore syringes and liquid culture syringes. However, spore syringe users will not see growth for an additional 1-3 weeks during the germination process without the use of Spore Boostr. This is because liquid culture syringes contain live mycelium whereas spore syringes contain fungal spores that need to become mycelium.

⚠️ IMPORTANT: If you choose to use spore syringe without Spore Boostr

DO NOT shake the bag immediately after inoculation. Doing this may prevent the fungal spores from germinating.

Frequently Asked Questions

We recommend using at least 2.5-5ccs, but up to 15cc, of your favorite spore syringe or liquid culture syringe. Higher inoculation rates may improve colonization times and mitigate contamination.

No, each ShroomTek Bag should only be used once.

ShroomTek is shelf stable and is viable within the first year after manufacture, and likely longer. However, we have found best success can be achieved if you use it within 30 days of receipt.

ShroomTek includes a 5ml vial of Spore Boostr, which is a nutrient-rich broth that turns slow-growing spores into fast-growing liquid culture. If you're using a spore syringe, simply inject your spores into Spore Boostr before inoculating your ShroomTek bag and allow them to germinate. After 1-2 weeks, when you see visible mycelium, it's ready to inoculate your ShroomTek bag.

ShroomTek combines sterilized grain and nutrient-rich substrate in one ready-to-inoculate bag, so your entire grow happens in one place—from inoculation to harvest. It’s beginner-friendly yet powerful enough for experienced growers seeking simplicity.
