B+ Psilocybe cubensis spore vial

Who doesn't know the B+ magic mushroom? This all-round cubensis is one of the strongest "survivors" on the market. Because the B+ is so resilient, it can even grow well in colder temperatures and can easily be spawned outside. B+ can grow mushrooms as long as your underarm. B+ is so efficient that it only stops fruiting when there are close to zero nutrients around and the mycelium can no longer be supported. When you are new to mycology, this strain is a very good one to start off with.

Product Description

B+ magic mushroom spore vials are produced under sterile conditions and should be kept dark and refrigerated (2-8°C) to increase the shelf life of the spores.

    Vial vs. Syringes

    Spore vials are superior to the spore syringes in most fields. Get the best results when cultivating B+ magic mushrooms with this quality spore vial. Using spore vials will result in a higher success rate in the colonization and fruiting process.

    Reasons to go Vial:

    • Longer shelf life than most spore syringes (2 years vs 6 months)
    • It's easier to get ALL spores out of the container. Plastic syringes are often charged with static electricity making the spores stick to them. Glass vials are never charged, so 100% of the spores will come out.
    • Works great with liquid culture growth media. Syringes can be prepared with a different solution, rendering any liquid culture medium unusable.
    • Spore vial solution has over a 1000 grow parts per milliliter, versus 500 g.p.p. ml or even less in most syringes.
    • Professional look and feel
    • Takes up less space
    • Easier to transport



    • 1x Glass Vial with 10ml B+ p. cubensis spore solution
    • 1x Sterile 10ml Syringe
    • 2x Alco Preps


    Instructions to use a B+ spore vial

    The vials have a cap with a circular rubber membrane. The rubber membrane, or septa, can be pierced by the needle of a syringe, but will stop any airflow, micro organisms or anything else to go through by itself. 

    Shake the B+ spore vial vigorously to spread the spores evenly throughout the vial. Sterilize the septa with an alco prep. Unpack the sterile syringe and remove the protective cap from the needle. Insert the needle of the syringe through the septa.

    The point of the needle should be submerged in the spore solution. Pull back the plunger of the syringe slowly so that the syringe will fill with spore solution. Just 3 milliliter of spore solution is needed to colonize 1 liter / 1.05 quart of substrate. After having filled the syringe with the required amount of spore solution, slowly take out the needle from the vial.

    To proceed from here to the inoculation process, there are several methods to choose from:

    Dropping the spore solution onto the substrate

    After having prepared your own substrate or cakes, you can drop the B+ spore solution directly from the syringe onto this. Press the plunger slowly so that dropplets of spore solution will come out of the needle. Every dropplet that will be in contact with the substrate is a potential mycelium growth point. Spread out these dropplets over the substrate evenly to colonize the substrate with mycelium.

    Injection through injection ports

    This is almost identical as dropping the spore solution onto the substrate. Open the injection port by pulling back the port protection cap. Use a alco prep to sterilize the injection port entry. Pierce the opening with the needle. Now drop the spore solution evenly over the substrate inside the spawn bag or grow box. After the B+ spore solution is injected, remove the syringe and close the injection port with the port protection cap.

    Liquid culture for faster colonization and stronger mycelium

    When injecting the B+ spore solution in a 'bath of nutrients', such as the Liquid Culture Growth Medium, the spores will form into mycelium inside this liquid suspension. This is called liquid culture or LC for short. Liquid Culture Growth Medium itself can be used to inoculate substrate and cakes. Liquid culture growth medium has a higher success rate and will be much more reliable than trying to germinate the spores without the use of  LC. In short: Using LCs will increase the chance on mushrooms.

    Note: The Liquid Culture Growth Medium will not work well with our spore syringes.

    Study spores and research using a microscope

    Seen from a scientific point of view; all Psilocybe cubensis are alike. But they do differ slightly in appearance and fruiting speed (phenotype). There are numerous Psilocybe cubensis that have different phenotypes. These different cubensis are not considered subspecies, but different strains. The B+ is a strain of Psilocybe cubensis.

    The differences in phenotype can be seen with the naked eye, but the true beauty lies under the microscope. The wondrous world of the spores. Many of our customers are scientists, doing research on these differences in a homemade laboratory. After having prepared your microscope slide, drop some of the B+ spore solution on it. Cover the specimen with a microscope covering glass. The best magnification for Psilocybe cubensis and Panaeolus cyanescens spore research is a magnification of 1000x or higher.

    The syringe and reusing it

    After using the syringe to inoculate the substrate, cake, or LC  with B+, you can reuse the empty syringe after you have sterilized the needle. This can be done with a spirit burner or lighter. Burn the needle by keeping it in the flame long enough to make it glow orange. Let it cool down before you insert the needle again. Instead of reusing one, you can also order a sterile needle separately.


    Store the B+ vial in the refrigerator between 2°C - 8°C or 35°F - 46°F. Leave the 'septa protecting stopper cap' in place when storing the vial. After removing this protective cap, always sterilize the septa with an alco prep before you insert the syringe.

    B+ spore vials can be stored this way for 2 year after leaving our warehouse.

      Good B+ Review by Oli
      It took much time the growth process to begin.
      Grow slowly, not abundantly.
      Had 3 waves. (Posted on 11/3/2022)
      HAPPY CUSTOMER Review by Max
      I received two vials and both of them were vital. I am very satisfied and I do recommend this product.
      Very fast delivery as well. (Posted on 4/7/2021)
      Reliable B+ - good for beginners Review by Steve
      B+ has a reputation as a forgiving tolerant fast-colonising strain that reliably produces generous flushes. I found that to be the case with mine. I even got a single mushroom of 122 grams, my largest yet. (Posted on 2/15/2021)
      Good Review by Mohammad
      It works. thanks. (Posted on 1/26/2021)

      great fast growing Review by Grant
      very fast from inoculation to fruit... nice healthy size fruits. highly recommended (Posted on 1/3/2016)
      Not what I expected but still good Review by Edward
      It was my first time using this so I did not get such good results. I did nnt know how much to use and I broke some of my jars when I left the rye grain cooking without water . I managed to get enough colonized for 1 1l box out of the syringe. I have not grown the mushrooms yet because it is not ready yet. If you are looking for something interesting to do this is a good option. But if its just mushrooms you are after the B plus mycelium boxes are much better. Some of the mushrooms I got from the B Plus mycelium boxes weigh 15 grams most 10 grams. Very easy to grow. Spray 5 times every 2 days with water and not too bright light. A kind of shaded area is best. 3 weeks later almost the whole surface is covered with huge 10 gram mushrooms. Very fast delivery. This is the best website to buy mushroom stuff from. Fast customer service as well. (Posted on 5/29/2012)
