There's little info. Almost pure sativa for outdoor cultivation that is mature and ready by the end of September. The high is sativa-like and uplifting.

    This almost pure sativa was developed for outdoor cultivation in colder climates and finishes very early - by the end of September. It also performs wonderfully indoors.


    A high THC content. A clear, stimulating, creative high with some indica body buzz. A Cannabis Cup winner.

    Good for:

    Complex and unique. Citrus, anise, spice and lots of other flavors.


    Serious 6 was created by mixing genetics from Canada with Sativa-landraces from Africa through a long process of selection and cross-breeding. We wanted to create a strain, which is very mold-resistant and will finish EARLY outdoors in a humid and cold climate at the end of September. Outdoors she grows tall and slender with full buds with very few small leaves and a particularly thick layer of cristals. Half of the plants will show beautiful pink pistils. At the end of flowering these pink colors are substituted by purple colors of the calyxes and leaves. The Serious 6 is an almost pure Sativa with a very short flowering time, which also gives amazing results indoors. She will fill up and produce dense long buds glistening with trichomes.

    The aroma of Serious 6 cannot be compared to other cannabis varieties, it is built up in layers; citric, anise, spicy are only a few of the recognizable aromas. Her effect is a cristal clear head-high, which will get you active and creative.

    At the Spannabis 2013 an indoor bud was tested at the CANNA-lab with 17% THC, that was the highest measured THC-content of ALL strains tested that day!
