The famous B+ cubensis is our best selling spores. This fungi is the most versatile cubensis around. Adapting and growing in such a wide range of temperature conditions and substrates in nature. It truly thrives to spread spores and it’s a very heavy spore depositor. Mr. G is the founder of this one and deserves a big pat on the back. The B Plus spores were originally found in Florida, which is not surprising since cubensis grow throughout the state year round. This has been our all time best seller for years and Mr. G should be proud for finding such a fantastic cubensis. The B+ has been witnessed growing outdoors in nature fruiting several times in a wide range of temperatures and substrates. Several times one winter, night time low of 45F, day high of 60F, the B+ just flourished. This is unusual for cubensis mushrooms to grow in such cool temperatures. Cubes are more common in warmer subtropical temperatures, 75F to 95F.  We've heard so many good reports back from growers in Amsterdam that just love this mushroom and how easy it grows and how beautiful it is. The B+ is loved by many. 

For microscopy details on the spores, look in the SPECIFICATION tab.​

Due to high demand and limited stock, the B+ is limited to 8 per customer temporarily.

Fast shipping. Sterility is good. Very vigorous strain - fast colonizer.

I was a little sceptical sending straight cash through the mail because that is something that can easily screw you. Though I put my trust in this website and they are awesome!
Quick shipping speed friendly cs. Spores look great thank you very much!
