Uncle Ben’s Tek: Is It Worth Using for Shrooms?
Growing mushrooms is now easier than ever. Low-cost methods like Uncle Ben’s Tek let many people grow magic mushrooms at home. This article explains how the method works. It also covers why it is popular, and how it compares to other ways to grow mushrooms for those who want to begin small and then grow more.
Why Uncle Ben’s Tek Is Gaining Popularity
People have become much more interested in growing mushrooms at home in recent years. This is especially true for magic mushrooms, grown for personal use or research. Uncle Ben’s Tek is a favorite for new growers. It is also liked by people who use psychedelics for healing, creativity, and personal growth. This method is popular because it is easy to get started with and simple to do.
Other growing methods are more complex. But Uncle Ben's Tek does not need a lab setup. You do not have to do many sterile steps. There is no need to make your own substrate or clean jars. You can also use things you find in most grocery stores and pharmacies. So, Uncle Ben’s Tek is a good way to start. It works well for people who are just curious or want to learn about psilocybin mushrooms for healing.
What Is Uncle Ben’s Tek?
Uncle Ben’s Tek is a simple, effective way to grow mushrooms. It uses pre-cooked, packaged rice as a growing base. "Tek" means "technique." This method started online in places like Shroomery.org. Users there made and shared easy ways to grow mushrooms with few tools.
Here is the basic idea. A sealed bag of sterile brown rice, usually Uncle Ben’s Ready Rice, can be a sterile growing spot. This happens when you add mushroom spores or liquid culture correctly. Growers put spores into the closed bag. Then, they let mycelium grow over the rice. After that, they move the rice with mycelium to a place where mushrooms can fruit. The rice is already wet and cooked inside a sealed bag. This makes it a mostly sterile place for growing at the start.
This process is not perfect, and it is not sterile like in a lab. But it is very easy to start. This makes it a great way to begin growing mushrooms.
Why It Appeals to New Growers
If you are learning how to grow magic mushrooms for the first time, Uncle Ben’s Tek is a good practice method. Here are the main reasons many people use it:
- No specialized equipment needed: Forget about pressure cookers, grain preparation, or laminar flow hoods.
- Minimal sterilization steps: Since the rice is sealed, fewer opportunities exist for introducing contaminants early on.
- Affordability: The startup cost is low—often under $30 for your first grow.
- Quick preparation: The setup can be completed in less than 30 minutes.
- Low commitment: Great for experimental batches or single-use attempts before investing in more robust setups.
For many, growing even one batch of mushrooms with this method is enough. These results are also often enough to make them want to try bigger or more long-term ways to grow mushrooms later.
What Type of Rice Do You Need?
Not all pre-cooked rice works for growing mushrooms. Using the wrong kind often leads to contamination and poor growth. Here is what to look for:
-
Fully Cooked Brown Rice: Brown rice has more nutrients than white rice, especially the complex carbohydrates and trace minerals needed by mycelium. Avoid enriched or glossy rice.
-
Minimal Ingredients: Choose bags where the ingredient list is limited to just brown rice and water. Avoid oil, butter, salt, preservatives, or seasonings.
-
Moisture Content: Check that the rice has a fluffy but not mushy texture. Too little water and mycelium won’t colonize well. Too much, and bacteria will thrive.
-
Microwave-Safe Bags: These are manufactured under strict conditions which provide a semi-sterile growing environment. Brands like Uncle Ben’s, Seeds of Change, and 365 by Whole Foods are popular due to their simple processing and consistent quality.
Check expiration dates and make sure the package is not damaged. If seals are broken, there is a much higher chance of contamination and failed growth.
Materials Checklist: Everything You Need
Before you start, make sure you have everything you need to do this technique safely and cleanly:
- ✅ Uncle Ben’s Ready Rice packs (brown rice, unflavored)
- ✅ Mushroom spore syringe (or liquid culture)
- ✅ 70% isopropyl alcohol & paper towels
- ✅ Microflame or butane lighter for needle sterilization
- ✅ Sterile gloves and medical face mask
- ✅ Micropore tape or injection port stickers
- ✅ Still Air Box (SAB) or draft-free workspace
Optional but helpful materials include a digital thermometer, humidity gauge, and disposable scalpels for moving colonized rice into fruiting containers.
Step-by-Step Process: Growing Shrooms with Uncle Ben’s Tek
Let’s walk through the full procedure from inoculation to fruiting:
-
Sterilize Your Workspace
Start in a clean room. Wipe all surfaces with 70% isopropyl alcohol. Wash your hands well. Wear gloves and a face mask to keep airborne particles down. -
Heat-Sterilize the Spore Syringe Needle
Flame the needle until it's red-hot. Wait 10–15 seconds to cool before injection to avoid killing spores. -
Inject the Rice Bag
Select a flat area on the bag. Wipe with alcohol and inject 1–2 mL of spore solution or liquid culture through the plastic. Aim for the middle or bottom layer for best colonization distribution. -
Seal the Hole
Immediately place micropore tape over the injection site to prevent contaminants from entering. Alternatively, use bags with self-healing injection ports. -
Optional: Gently Mix Contents
Some users lightly shake or massage the bag post-injection to spread spores evenly. Do this with extreme care — don’t rupture the bag. -
Set Aside to Colonize
Store in a warm, dark area (ideally 72–76°F / 22–24°C). A drawer, cabinet, or closet works well. -
Monitor Colonization
In 7–14 days, expect signs of white mycelium growth. Continue monitoring over the next 2–4 weeks, depending on the species and ambient conditions. -
Initiate Fruit Body Formation
Once 100% colonized, transfer the rice to a fruiting chamber like a shoebox or a simple plastic bin setup. Add a top layer of coir or vermiculite if desired. Mist daily and provide light 12 hours per day.
Timeline: How Long Does Uncle Ben’s Tek Take?
| Stage | Duration |
|---|---|
| Colonization | 2–4 weeks |
| Pre-Fruiting (after 100% colonization) | 3–5 days |
| Fruiting (mushroom growth) | 1–2 weeks |
| Total Time From Start to Harvest | Approx. 4–6 weeks |
This makes Uncle Ben’s Tek one of the quickest ways to grow magic mushrooms compared to other grain spawn or log-based methods.
Risks and Contamination: Keeping Things Clean
Uncle Ben’s Tek is not fully sterile. This means contamination is always a risk. Here are possible risks and how to lessen them:
- Bag Puncture or Damage: Exposes rice to ambient spores and bacteria.
- Unclean Injection Practices: Don’t skip needle sterilization—this is the most common vector for contamination.
- Excess Moisture or Oil: Creates anaerobic pockets where bacteria thrive.
Red Flags:
- 💚 Green: Trichoderma mold
- 🖤 Black: Aspergillus
- 🛢️ Slime or foul odor: Bacterial infection
Avoid opening contaminated bags. Dispose of properly and sanitize your space before starting over.

Uncle Ben’s Tek is like the training wheels of mushroom growing. It's great for learning. But people who grow mushrooms for a long time often move on to bigger setups, like grain spawn to bulk substrate systems.
Case for Growing Magic Mushrooms with Uncle Ben’s Tek
This method can fully grow Psilocybe cubensis. This is a popular magic mushroom species. It is known for being hardy and growing fast. P. cubensis is good for beginners. It grows well in the rice bags and responds well to simple fruiting setups like basic bins or shoebox teks.
A 2022 study (Sebastien) found about 70% of new growers used Uncle Ben's Tek for their first try. This was because of its low cost and small effort needed. The method works well enough for microdosing, medicinal use, or checking how pure a culture is.
Best Practices for Maximizing Yield
Uncle Ben’s Tek is simple. But you can make it better with some tricks to get more mushrooms:
- 🌡️ Maintain colonization temps between 72–76°F
- 💦 Boost humidity during fruiting with regular misting
- 💡 Use a 12/12 light cycle using indirect sunlight or LED lights
- 🚰 Consider a casing layer to retain surface moisture
- 🔁 After harvesting, dunk rice in water for 24 hours to trigger a second flush
These additions can turn a simple grow into a surprisingly productive one.
Troubleshooting: When Things Go Wrong
| Problem | Likely Cause | Fix or Prevention |
|---|---|---|
| No mycelium growth | Dead spores or unsuitable rice | Check spore quality, use brown rice |
| Mold or slime | Contamination from unsterile technique | Improve sterile setup and workflow |
| Slow colonization | Temperature too low | Warm up storage area |
| Mushrooms won’t fruit | Poor humidity, no lighting | Begin misting, introduce light cycle |
| Bag dries up | Heat and airflow exposure | Keep in enclosed, humid area |
When grows fail, it helps you learn. Each try makes you understand more about how mycelium acts and what conditions it needs.
