Blackberry Widow, Purple Urkle, Grandaddy purple, purple kush. those are a few potent varieties but arent the easiest to get. a few you may find easier are.

dj short's-blueberry, flo

dutch passion's-purple#1, purple star

paradise seed's-sweet purple

reefermans seed's- potent purple, purple g-sus, purple pineberry

now are you growing indoors or outdoors cuz most of these are suited for indoors plus it's late in the season to start outside. secondly if you are only growing for profit your setting yourself up for failure. goodluck on your search for the purple haze doggg next time look for dat dro i heard dats real fiya hahaha
