Fast flowering Sativa with pink pistils!
Serious 6 was created by mixing genetics from Canada with Sativa-landraces from Africa through a long process of selection and cross-breeding. Serious Seeds 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 crystal 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!

Serious 6 Feminised Seeds - 6
Huge leaves that are pretty wide but the African pedigree is clear in how large the plants get. Really hardy and will push through the multiple toppings that are needed to keep the height of this one sensible. Takes the cold and damp well and most are indeed early to ripen. Some of these are near enough the perfect outdoor plant and you can tell the breeding work that has gone into these. Really worthwhile for the outdoors in less than perfect climates, highly enjoyable stuff.

Perfect for those in wet/humid/cool regions.. early finisher. Some phenos display beautiful pink pistils! Almost pure sativa so those looking for an indica/hybrid couch-lock type effect might be disappointed, but do some research before you buy son

Serious 6 Feminised Seeds - 6
Very special variety, magnificent plants, homogeneous in structure, growth characteristics and appearance. Fast flowering outdoors, revealing very aesthetic pink/purplish pistils at the end of flowering. The taste is unique and very complex, sweet, spicy, floral, some notes of anise clearly recognizable at times, pleasant and persistent fragrance. The effects are of medium strength, very cerebral and motivating, an excellent herb for active days. It's really not a sleeping variety.

Not sure why the other guy says these suck, cause they don't. I just finished curing a great crop of large tasty buds and they give me a great buzz without the couch lock that indica's tend to produce. Serious 6 buds are large, tasty, give a great high and lots of energy to boot. They are even ready after a short (8 week) time of 12 on and 12 off. I used the SCROG method of growing and am very happy with the quality of these sativa seeds.

Frequently asked questions
Is this strain suitable for my growing environment?

In theory most strains can be grown outdoors, indoors or in a greenhouse but how well they perform depends on the more exact environmental conditions. This is most important outdoors where climatic conditions can vary widely, so please check the strain information carefully. If your climate is more extreme or growing season shorter you should choose strain that is specifically adapted. Indoor and greenhouse environments can be controlled and made suitable for most strains although space can be a factor for strain that grow very large.

How difficult is this strain to grow?

Growing difficulty varies depending on a strain's resilience, structure and environmental needs. Some strains are more forgiving and better suited to beginners and a range of environmental conditions, while others may require closer control of factors such as light, humidity, temperature and feeding.

What can I expect in terms of cannabinoid content and yield?

Our product information and that provided by suppliers can be an indication of potential levels under optimal conditions, and it should not be assumed that results can be replicated in all conditions.

Is this strain suitable for beginners?

Strains described as beginner-friendly, easy to grow or resilient, in particular Autoflowering Feminised strains, are generally more manageable for less experienced growers. These varieties are often a more reliable starting point than more specialised genetics.
