If you’re interested in growing B+ magic mushroom spores, you’re in the right place. This strain is known for its adaptability and ease of cultivation, making it a great choice for beginners. In this guide, we’ll walk through the step-by-step process of cultivating B+ liquid spores into fully developed mushrooms.

Before we dive in, it’s essential to note that growing magic mushrooms is subject to legal restrictions in many places. Always research your local laws before starting.

What Are B+ Liquid Spores?

B+ magic mushroom spores refer to the microscopic reproductive units of the B+ strain. When suspended in a liquid culture solution, they become what’s known as a “spore syringe.” This liquid suspension helps speed up colonization and is easier to work with than dry spores.

What You’ll Need

To successfully grow B+ mushrooms from liquid spores, you’ll need:

• A spore syringe containing B+ liquid spores
• A sterilized substrate (brown rice flour and vermiculite are popular)
• Mason jars or grow bags
• A still air box or glove box (to maintain sterility)
• A pressure cooker or autoclave
• A fruiting chamber (such as a monotub or SGFC)
• Perlite or another humidity-retaining medium

Now that you have your supplies ready, let’s go through the process.

Step 1: Preparing Your Substrate

The substrate is the food source for your spores, so it needs to be properly prepared. A common beginner-friendly recipe is the PF Tek method, which uses:

• 2 parts vermiculite
• 1 part brown rice flour
• 1 part water

Mix these ingredients thoroughly and load them into sterilized jars. Cover the jars with a breathable lid (like a coffee filter or micropore tape) to allow gas exchange.

Step 2: Sterilization

To prevent contamination, sterilization is crucial. Place your jars in a pressure cooker and sterilize at 15 PSI for 60–90 minutes. If you don’t have a pressure cooker, boiling for 90 minutes is an alternative, though less effective.

Step 3: Inoculation with B+ Liquid Spores

Once the jars have cooled, it’s time to inoculate them.

1. Sanitize your workspace. Use isopropyl alcohol to wipe down surfaces and wear gloves.
2. Use a still air box (or glove box) to minimize contamination.
3. Shake your spore syringe to evenly distribute spores in the liquid.
4. Inject the spores. Insert the needle into the jar (through an injection port or micropore tape) and inject about 1-2 cc of liquid spore solution.

After inoculation, store the jars in a warm, dark space around 75–80°F (24–27°C). Within 1–2 weeks, you should see mycelium growth.

Step 4: Colonization

Let the jars sit undisturbed while the mycelium takes over the substrate. Full colonization usually takes 3–4 weeks. Once the jars are fully white with mycelium, they’re ready for the next step.

Step 5: Fruiting

Now, it’s time to introduce fresh air and humidity to trigger mushroom growth.

1. Prepare your fruiting chamber. Line it with damp perlite to maintain humidity.
2. Move the colonized cakes (or bulk substrate) into the chamber.
3. Mist and fan the setup daily to encourage growth.

After about a week, you should start seeing mushrooms forming.

Final Thoughts

Growing B+ magic mushroom spores takes patience and attention to cleanliness. By following these steps, you can successfully cultivate this strain with minimal issues. Remember, research legalities before starting, and enjoy the fascinating process of growing fungi!
