The infamous B+ strain of cubensis... what a chameleon this one is. This is by far the most versatile cubensis we've ever seen. Adapting and growing in such a wide range of temperature conditions and substrates. It truly thrives to spread its seed, which by the way its a very heavy spore depositor. Not only does it grow easily indoors, we've seen the B+ fruit outdoors several times in a wide range of temps and substrates. Several times one winter, night time low of 45F, day high of 60F, the B+ just flourished. Spring/summer, low of 75F, high of 90F, the B+ once again fruited beautifully. We've seen it grow on alder wood and fruit, compost, straw,dung,rice, and it especially loves bird/finch seed. We've heard so many good reports back from ppl that just love this mushroom and how easy it grows, and how beautiful it is, its loved by many.
Although the B+ is not a super fast colonizer, its speed is average, producing some very large mushrooms that are generally a caramel color. Grown in cooler temperatures, it usually always produces a very beautiful color caramel cap and stems. The stems are generally very thick, and it produces some large caps. It also drops a very thick veil. Grown in warmer temps, its color changes to a more golden color at times.
The B+ cubensis has been around for a while. It was brought to us by a grower that went by Mr. G. There was a lot of controversy surrounding this mushroom for so long because Mr. G started off by telling everyone it was an azure/cubensis hybrid. Although at times it does grow some broadly umbonate caps like Psilocybe azurescens, it is just a unique cubensis. But a huge thanks to Mr. G, where ever you are these days, for bringing us such a beautiful mushroom. We like to refer to this one as "super strain". It really is a superior cubensis in many ways.
This is a Hawk's Eye Favorite and belongs in everyone collection!
These were grown outdoors in a greenhouse, on a mix of 2:1 finch seed to vermiculite, then cased using the 50/50+ tek and mix.
