Cadillac Rainbow is a hybrid weed strain made from a genetic cross between Pure Michigan and Runtz. This strain is a gassy and fruity hybrid that has a lemon and diesel flavor with hints of cherry and mint. Cadillac Rainbows is a potent strain of cannabis that has a powerful concentration. With such a punch, we only recommend this flower for experienced users. Newbies can sample a small amount, but it may be too intense and knock them flat on the couch, where they’ll remain until it wears off.
