RKS is derived from a cross of Afghani, Colombian and Thai land-race strains to produce a sativa dominant variety of cannabis with an old school terpene profile. DNA's test grows of this strain, conducted in their legal climate, showed strong plants with a high calyx to leaf ratio and larger than average yields.

RKS has a very pungent aroma, reminiscent of classic Skunk strains: the use of carbon filtration was essential to control the odours. Uplifting effects are the order of the day with RKS - a long lasting, euphoric effect with lovely old school flavours.
