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.

They shipped fast arriving in just 2 days with normal shipping+ warmer. Specimens were alive, plentiful and sterile. I've shopped at a few vendors for my mycology research however this has been the best site i have ever dealt with. I plan to return for my future research requirements. Thank you for the fast shipment and professional preparation of the specimens.
