Vortex is definitely a one and done strain - one hit and you are on your way. The jury at the High Times Medical Cup agreed when they awarded it as Best Sativa in 2010. TGA Subcool obviously has his favorites and Vortex is the offspring of two of them. He crossed Apollo 13 and Space Queen, both varieties with high potency and copious amounts of resin.

Vortex is definitely an exceptional variety, all it takes is one toke and you are on your way - on a long way. Everybody has his favorites and this is a cross of two. TGA Subcool really went to town when he crossed Apollo 13 and Space Queen, because both are varieties with a high potency and copious amounts of resin.

The outcome of welding those kick-ass genetics together is a variety with a significant Sativa dominance, but despite the 80% Sativa share the plants grow up to wide bushes of a short to medium height, provided you prune and trim them properly to support the development of ramification. The rather small size makes Vortex the perfect choice for the ScrOG method. Another astonishing fact is the short flowering time of only 7-9 weeks, which is extremely short for a Sativa.

Vortex plants share the traits of both parents and develop very long, rocket-shaped buds with a pointed top. The incredible amount of trichomes covering the buds makes then sticky to the touch and gives them a look as if they had been rolled in sugar. And Vortex is not miserly when it comes to harvesting, brought up with a competent hand you can expect a yield of 100 grams from a 100cm plant.

The aroma of the end product varies from phenotype to phenotype, so Ill list only a few flavors here. Self experienced and aromas reported by other breeders and users: Mango with lemon, baby diarrhea and rotten fruit with a slight dash of fuel, lemony chemically musty smelling, sweet and sour. The strange part about those reports is that all agreed that the buds with the "baby poop" smell were the most potent.

The dried and properly cured end product contains roughly 18% THC and you surely wont be disappointed by the instantly and hard-hitting and long-lasting effects of this smoke. One hard rip and you will feel full of energy, confused and stoned, inspired and freed from anxiety and mental stress, but also driven to stupid laughing fits. The smoke tastes like mango with a hint of fuel, with a dash of spice. This is one of the best Sativa experiences you will ever encounter. The jury at the High Times Medical Cup agreed when they awarded it as Best Sativa in 2010.
