Flesh-N-Bone is hoping to smoke the competition in the weed biz ... 'cause the Bone Thugs-N-Harmony rapper claims he's created his own unique strain of cannabis and he's now trying to get it in pot shops across the country.
Flesh -- who happens to be an avid ganja enthusiast -- has named his new creation "Phifty Caliber Kush" ... and says the strain was created to help with pain relief.
A rep for the rapper tells TMZ ... Flesh has already signed a deal to sell PCK at a dispensary in Flint, MI ... and hopes to expand to California, Colorado and Washington in the near future.
Flesh isn't just selling the bud -- he's also selling the seeds ... hoping people in the stoney crowd can pull themselves away from The Cartoon Network long enough to grow their own stuff.
