Pop Rocks, also known as the Pop Rox strain,  is one of those strains that you hear people whisper about, and only a few people ever get the chance to use it. The Pop Rocks strain is said to originate from a hidden collection in Las Vegas, Nevada, and is available only at one very secretive store. The breeders of this elusive strain are also unknown – so is its lineage – but rumor has it that Pop Rocks is an Indica-dominant strain that’s part of the Purple family. It’s almost as if the strain itself is as secretive and mysterious as a covert government project – only this time, the objective is to conceal some of the best marijuana.
