Magic Mushroom spore syringe B+ Cubensis

Who doesn't know the B+ magic mushroom? This all-round cubensis is one of the strongest "survivor" on the market. Because the B+ is so resilient, it can even grow well in colder temperatures. B+ can grow mushrooms as long as your underarm.with thich sometimes hollow stems. And large brown caps.

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+ 20 ml magic mushroom spore syringes are produced under sterile conditions and should be kept dark and refrigerated (2-8°C) to increase the shelf life of the cubensis spores.


  • 1x 20 ml B+ spore solution in a 20ml syringe
  • 1x sterile needle
  • 4x Alcohol prep/swap

How to use the B+ spore syringe

The B+ spore solution is held inside the syringe by a luer lock stopper on the end where the needle goes. With this luer lock stopper attached makes it easier to transport and to store the B+ spore syringe.

Make sure to work as hygienic as possible. Wear a face mask and sterile gloves and/or disinfect your hands. Hold the B+ spore syringe in front of you with the luer lock stopper pointing upwards. Remove the luer lock stopper by screwing it counter-clockwise. Take the needle out of the sterile package and screw it on the B+ spore syringe. Shake the spore syringe vigorously for ten seconds before you remove the protective cap from the needle.

To proceed from here, 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 these. Press the plunger slowly so that drops of spore solution will come out of the needle. Every drop that will be in contact with the substrate will be a potential mycelium growth point, so spread out these drops all over the substrate to evenly colonize the substrate with mycelium.

How many cakes can you make with spore syringe?

One 20 cc/ml spore syringe can easily colonize 6 liters / 13 pints of substrate.

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.

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 or enthusiasts, 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.

Using liquid culture growth medium with the spore syringe

Add only a few ml (drops) of the B+ cubensis spores to a liquid culture growth media. 1-2 ml of spores are enough, but add a few drops more, just to make sure. We recommend using the Liquid Culture vails, but we'd love to hear your feedback on your results with your own liquid culture.

How to store a spore syringe

The B+ spore syringe should be stored refrigerated in a temperature between 2°C - 8°C or 35°F - 46°F. The shelf life of the spore syringe is at least 12 months after they leave our warehouse.

Top Quality Review by Mr. Fungi
Fast delivery, good strong genetic, no contamination (Posted on 10/4/2023)
The mycelium is growing vigorously. Review by Thoor
The syringe is very easy to handle and since it contains 20 ml it goes to several more inoculations for a great price.

The spores have now turned into beautiful super white mycelium. Looking forward to next stage. (Posted on 7/5/2022)
All good Review by Rado
Good product, fast delivery and best prices I could find. So definitely recomend. (Posted on 6/24/2022)
amazing Review by Nina
I was worried when mistakenly had the unopened spores sitting at room temp for a week before I knew to refrigerate them, but even with that stress they took to my substrate like a charm! I have two spawn bags completely germinated and ready to move to the next phase after exactly 3 weeks in darkness. I also choose to buy the mushbag rye substrate bag they offer here, and it all worked perfectly! (Posted on 5/7/2022)

Very satisfied with this product. I am a beginner in growing mushrooms and it worked out just fine for me! (Posted on 3/15/2022)
Great spores Review by Martin
These spores were great, I managed to inoculate grain jars despite my lack of knowledge and technique after having sterilized them in a PC.
I highly recommend them ;)

Nice spores Review by Great
Good spores , you need to really shake your syringe very well . Nice product (Posted on 10/2/2021)
Hungry little invisible monsters Review by Willempie
Injected these little invisible spores in BRF substrate. They were colonizing, spreading their little mycelium arms in next to no time, consuming everything in the bottles like little hungry monsters. No contam. About to fruit the cakes, so no shrooms yet, but by the look of the cakes this is going to be a good harvest. (Posted on 1/29/2021)

Very good. Review by Tomáš
Great product. Works perfectly. (Posted on 3/2/2020)
Not concentrated Review by Fred
I used 0,5ml per injection site. Only 1 in 4 sites germinated. Now, places that germinated show thick rhizomorphic growth but will take some time to take over the substrate. (Posted on 12/6/2019)
Good spores Review by FB
Great stuff, use 1ml per injection spot for a high colonization rate, 0.5ml is hit and miss. (Posted on 12/19/2018)
