Strain Description

The result of a selection work, research, and crossing for optimized genetic characteristics! 

Flowering INDOORS is ONLY recommended to EXPERT growers, as a tiny portion of the plants can have hermaphroditic tendencies (2 out of 100 plants are stress-sensitive to light stress). Outdoors under natural light that is no problem, Serious 6 grows tall and slender with full buds, only a few small leaves and a particularly thick layer of crystals.

Genetics:

The genetics of Serious 6 is a long work of selection and crossing between local African sativa varieties and Canadian genetics.

Taste and Aroma: 

The aroma of Serious 6 buds is extremely complex: lemony, aniseed, fresh and spicy, are just a few of the recognizable flavors! Serious 6 will delight terpene hunters! 

Its Cultivation:

 Outdoors, Serious 6 cannabis plants are ready to be harvested even in northern climates by the end of September at the latest. Serious 6 grows tall, with full flowers and low foliage. Throughout the flowering of Serious 6, an extremely thick layer of resin crystals forms. About half of the plants display beautiful pink flower pistils. Serious 6 also has pink hues  during growth, which are replaced by purple tones in the flowers and leaves towards the end of the flowering period.

Our advice is to not start the seeds indoor before April 15th to prevent early onset of flowering and revegging when the plants are put outside too early.

Its Effects:

Serious 6 has fundamentally a moderately strong effect on the Mind (a little bit Activating or Creative  and also a hint of Thoughtful or meditative) in short: a crystalline high in the head that activates and makes you creative, but also affects physically a bit.

In a few numbers:

Flowering period: 53 days or 8 weeks 

Harvest potential: Indoor: between 350 and 500g/m2, Outdoor: 500 - 1000 gram per plant
 

In a few words:

Serious 6 is a very mold-resistant and very early outdoor variety, finishing in September in a humid and cold climate. The plant, with thin stems, grows tall, with well-filled heads under a very thick layer of crystals. Half of the plants have very pretty pink pistils, some plants have purple hues. Serious 6, an almost pure Sativa variety, has a very short flowering time (8 weeks) and a surprising yield indoors. Long and dense heads shiny with trichomes (hairs) of an aroma in different layers: lemon, anise, spices, and others. A clear as crystal water, active, and creative cerebral effect. Serious 6 finished 2nd at the Higlife Cup 2013 in Amsterdam, in the BIO-Weed category.

A bit of history:

-At Spannabis 2013, an indoor bud was tested in the CANNA laboratory and had the highest measured value of all herb varieties that day with 17% THC!

Serious 7 - Additional Information:

We have been working for years to improve Serious 6. Not so easy. Now, we have something that might be interesting for people. Serious 7: a more uniform plant than Serious 6 in all respects. The harvest date of Serious 7 is generally more similar to the older Serious 6. A bit less smelly than Serious 6, which is good against neighbors. More crystals make it a bit stronger and no pink pistils. Losing the pink colors is not what we wanted, but in breeding, one has to make choices and compromises. The pink colors of Serious 6 are beautiful as long as the plant is alive. The dried buds no longer have a pink color anyway. Serious 7 is a rewarding variety. One could say it's the white pheno of Serious 6. previously gave this variety as a promotional seed to get feedback from you. We received lots of positive feedback on Serious 7, and because of enough people liked it, we have put Serious 7 on our menu. It's thanks to our customers and their feedback that we improve!

I have been growing serious 6 in m in the backyard for 3 years now, 5 plants each time. I find it a surprisingly easy species to grow outdoors. They are in 30 liter pots and I have never once harvested less than 200 grams cut and dried per plant, with peaks of up to 350 grams. With her beautiful pink buds, they don't look out of place in the garden. She is wonderful to smoke and gives a good high. I'm going to use larger pots this year and see what that does to the yield.

First of all I want to thank customer service. I bought a pack of S6 seeds in Amsterdam, but for whatever reason none of them germinated. I contacted Serious seeds and they sent me a new pack for free. All of them germinated and gave me beautiful flowers by late September outdoors in a Mediterranian climate.The effect was as expected uplifting and inspiring. Definetely growing Serious 6 again.
