Kyle Kushman's Purple Kush (KKPK)

Very rare and very good soulshine cut. Pungent, with notes of "purple" (incense, perfume, musky grapes), and the spicy Kush end of the spectrum as well. Much like the smell, the flavor is is a dark fruity musk with a bit of sweetness at times - a great blend of the typical purple flavor and traditional Afghani/Pakistani Kush varieties. Relaxing and rather potent, Purple Kush is definitely in touch with its Afghani/Pakistani roots. Coming on with a slight rush of energy, that subsides quickly and leave the user with a floaty, highly medicated body experience that makes aches and pains as well as anxiety/stress melt away. Purple Kush is also known for being a long laster, normally going out to the 3 hour mark. Recommended highly for body pain, muscle relaxation, mood elevation, appetite stimulation, and sleep aid at higher dosages.

Flowering time 63 - 70 days.
Genetics: Probably Northern Lights x Purple Indica
