I've tried a few of Nirvana's strains and Wonder Woman is one of my favorites. Big yielder and the Highs good. Aurora indica is another good one but a smaller plant in height, but dense. I've never tried PPP, always wanted too. These are the Nirvana strains I have used. White Castle,Bubblelicous,Master kush,Aurora Indica,Northern Lights,AK-48,Black Jack(have it,haven't tried it yet) and currently Papaya. My favorites are Wonder Woman,Aurora Indica and White castle(med Yield).
Peace
