Royal Purple Kush CBD is a medical marijuana strain that produces three times as much CBD as it does THC. This plant can be vegged quite a long time to get the size you want as it only stretches about 15% - 25% during flowering. Royal Purple Kush is a 60% , 40% indica plant that was bred by crossing a Black Afghani with a Bubba Kush and a sativa CBD strain. sativa it flowers in 8 - 9 weeks; Indoors it should be ready at the beginning of October in the northern hemisphere. Yields are impressively high especially if allowed a longer period of vegetative growth. Its magnificent purple colours will be enhanced by lower temperatures towards the end of flowering or by the simple expedient of using cold water to feed both indoors and outdoors. The flavour is a combination of the sweet earthiness of the Black Afghani mother together with the fruit and pepper of the Bubba Kush male. The effect is very well-balanced providing energy along with relaxation. Cannabinoid levels are high and Royal Purple Kush provides a heavier stone than many purple varieties. The increase in both stature and yield is due to the effect of the sativa CBD plant.
