Serious Seeds Regular

The breeder behind Serious Seeds, Simon, is responsible for the material sold by the seed bank. He studied biology at one of the universities in Amsterdam and was always a non smoker. (Tobacco, and therefore also marihuana because in Holland it is common practice to mix the latter with 'tobacco', and roll a joint.) He only discovered the merits of smoking pure marihuana after his study while travelling through Africa in 1986. Today he remains one of the few dutch who smoke this wonderplant in its pure form as one should.*
From that moment on he st
arted collecting seeds. Back in Holland he immediatly started growing those seeds out for personal pleasure.

Crossing what he thought were the best plants seemed a natural follow up. Contacts with other growers gave him access to different plants from which he also selected the best ones. The genetic background of this material was not always clear.

Simon taught biology at a highschool when Alan Dronkers asked him to come and work at Sensi Seeds. It was quite a career change to do that but he never felt sorry about it. After some time working for Sensi he left and started a seed company with some American pot refugees.
That ye
ar (1994) the AK-47, as well as the 'Chronic', .won prices at the American Cannabis
AK-47 did strike again!!
In the dec 2003 issue of High Times magazine the AK-47 was chosen as plant of the year!! In the Cannabis Cup competition in 2003 the AK-47 won the 2nd place in the indica cata- gory.
The indica-cup
Yes the indica cup. And that while AK is classified as more sativa, how is that
? Well, if you take track of sativa/indica% over multiple generations and make a nice calculation you have an exact nr. with even 1/2 %. But that's on paper and real life is not that predictable.Imagine for example that during your breeding proces you choose from each generation the shortest, fattest, mostly kick-ass plants for next parents all the time.  Indeed, the % stays the same whatever plants you choose but the plants effect and looks will be more what we call indica like. Such is the case more or less.
Last ye
ars cup there were reversed entries al- ready, clear sativas in the indica category. And since AK is more approprietly described as an indica type of effect we decided to enter it under indica. But it needs a story to explain that and here you have it.

Serious Seeds Serious 6 (11 seeds)


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!

Type: F1-hybrid, almost pure Sativa
Recommended veg. time seedlings: 3-(4) weeks
Indoor flowering time: 55 - 60 days
Indoor yield: 400-550 gr/m2
Outdoor/Greenhouse harvest time: End of September

Serious Seeds Ak-47 (11 seeds)

 This easy to grow plant is our most popular. It is of medium height and produces good yields quite quickly. Extremely STRONG odor and smoke. Take extra care with odor control when growing near neighbors. The name was given not out of any idea of violence, but more in association with the ?one hit wonder? that the smoke is. Quality without compromise makes AK suitable for commercial grows or home use. These plants have a short flowering period for a sativa, producing compact, not too leafy buds that gleam with a coat of resin crystals.

Winning EIGHT prizes!! in Cannabis competitions, including second prize for the Best Sativa in the 1999 High Times Cannabis Cup, proves it is a favorite to smoke as well as to grow.

Type: mostly sativa
Indoor clone grow time: 5  10 days
Indoor flowering time: 53  63 days
Indoor yield: 350- 500 grams/m2
Outside/ Greenhouse harvest time:
15-31 October

Serious Seeds Bubblegum (11 seeds)


Bubble Gum is a medium tall, usually not too branchy (sometimes stretchy) plant, producing compact, crystal covered buds. Originally the Bubble Gum was developed by growers in Indiana, USA. From there the genetics moved to New England and eventually Holland. lt took many generations to finally produce this stable Bubble Gum, with the characteristic, sweet smell (truly resembling a typical bubble gum taste) and euphoric high; the original trademarks of this famous strain. The only inbred strain (no F1 hybrid) on the Serious menu.

Winner of two awards in the High Times Cannabis Cup of 1994, a 2nd place in 1995 and again a 2nd prize in 1999, gives Bubble Gum a total of 4 awards from the judges.

Type: sativa/indica hybrid
Indoor clone grow time: 7 ? 14 days
Indoor flowering time: 56- 63 days
Indoor yield:300- 450 grams/m2
Outside/ Greenhouse harvest time

Serious Seeds Chronic (11 seeds)


Our most commercial variety, this medium height, not too dense plant is the perfect combination of good yield and excellent quality. Smokers that know and grow choose this plant for its combination of appearance and sweet smell. With its indica background Chronic can produce up to 600 g/m2 without losing that connoisseur feeling. Grows a single huge central bud with few side branches. Do not top plants to encourage multiple big buds, as this strain does not respond well. Mild, sweet smell develops while flowering, take care to dry thoroughly after harvest (before packaging) to maintain this subtle fragrance. 3rd prize High Times Cannabis Cup 1994, improved in 2000.

Of all our strains, this is the best choice for growers tired of losing quality when increasing yield.

Type: sativa/indica hybrid
Indoor clone grow time: 5 ? 10 days
Indoor flowering time: 56-63 days
Indoor yield: 350 ? 600 grams/m2
Outside/Greenhouse harvest time:
15-31 October

Serious Seeds Kalimist (11 seeds)


 Arguably the top sativa strain available today. With 90% sativa genetices, Kali Mist grows into tall, classically sativa plants with very few leaves. This strain produces dense clusters of full fluffy buds, producing much higher yields than you would expect. The plant structure and few leaves allow the light to pass all the way to lower branches, allowing bottom buds to develop fully. When planted outside early in the year this plant can grow very tall. Expect spiraling flowers with a high resin content and a delightfully spicy scent.

Kali Mist is often the choice of experts for their own stash grows.

Also, women particularly seem to like this strain, next to the sheer pleasure of smoking it, we received several reports that it works great against menstrual cramps.

We are proud to announce that Kali Mist was improved in 2000 to produce bigger yields. In Spain it proved to be very mold resistent, even outside during bad weather. This strain has flavor and subtle cerebral effect that gave it a Cannabis Cup first prize in 1995 (Hydro Cup) and again (with this new and improved version) in 2000 (Seed Company Sativa Cup)! Without a doubt the choice for connoisseur stash.
Gives a very strong, clear and energizing high.

Type: sativa
Indoor clone grow time: 1 - 5 days
Indoor flowering time: 70 ?90 days
Indoor yield: 300- 500 grams/m2
Outside/ Greenhouse harvest time; November

Serious Seeds White Russian (11 seeds)


These seeds produce plants that are fantastic in both appearance and effect. Our most typically indica strain, White Russian is a stable cross of AK-47 and White Widow (a prize winning indica clone). Medium height, consistent plants and dense, very resinous flower tops (crystals appear after about 5 weeks of flowering). With such a strong indica background, the plants smell quite strong during both their growth and flowering period. In an independent seed comparison in which over 150 different seedstrains were grown out in a greenhouse, the White Russian came out as the strongest plant (22% THC, likely to be the strongest plant known at present!!).

Winner of the overall Cannabis Cup in 1996 and of the Cup for Best Bio Grass in 1997. The plants yield very powerful buds, coated with resin.
Very strong, long lasting high, more cerebral than knockout. Medicinal plant.

Type: mostly indica
Indoor clone grow time: 5 - 10 days
Indoor flowering time: 56- 63 days
Indoor yield: 350-500 grams/m2
Outside/ Greenhouse harvest time;
15-31 October

Serious Seeds Warlock (11 seeds)


Although indica dominant, this plant really combines some of the best Indica and Sativa characteristics. Short and bushy during veg. but grows huge compact buds with few leaves in flowering. Few medium sized leaves with a massive amount of flowers make it easy to manicure. The clear white pistils change to a tan/pinkish color when ripe. Strong sweet smell with a tinge of sour, reminds of fresh fruits. The effect is a strong high, more felt in the head than in the body.

Serious Seeds Double Dutch (11 seeds)


Double Dutch is a cross between a Warlock male and a (Serious) Chronic. During vegetative growth, Double Dutch shows its Indica side with its wide leaves, heavy stem, and a bushy growth pattern. In the flowering stage Double Dutch produces giant Sativa-like buds, like its mother; the Chronic. All tips that receive enough light will form huge buds similar to elongated popcorn balls. Double Dutch buds must be staked due to their heavy weight. Performs well in bio, coco and hydro mediums. The Double Dutch aroma is a pleasant fruity wildflower scent. The effect is complex and strong; the cerebral high and pleasant bodily effect gave this plant several awards. In combination with its high yield a must trie for all serious' growers.

Serious Seeds Motavation (11 seeds)


This short/squad Indica plant is the final creation of a long process. In the parental lines are older plants 'Starwarz' & 'Medizin Power' fused into this ideal indoor plant. A thick layer of resin glands on the flowers and single leaves, makes manucuring less necessary, and gives her a popular presence in every grow room. Excellent for indoor and closet rooms with limited height. A powerful aroma, sweet with undertones reminding of fresh paint, developes during flowering. The effect is an overwhelming body stonedness, nailing you to the couch while your mind is fueled with creative ideas. Executing them however will have to wait till the effects wear off. Any 'boring' feelings will fall away after a hit of 'Motavation'! Medicinal plant!

Serious Seeds Biddy Early (11 seeds)


'Biddy Early is our first outdoor variety, and for western European countries already one of the best ever. It can easily reach 2 meters of height in a normal outdoor season. Its relatively early finishing time combined with a good resistance against molds make it very suitable for outdoor growths in dutch and similar climates. Most plants will show red and purple colors under low temperatures. The 'Biddy Early' gives great results indoors as well, but keeping mothers in a vegetative state is difficult because of its willingness to start flowering. The aroma is a mix of an unfamiliar Earthy scent and a Sweet Candy taste which gives a surprisingly pleasant and powerful high. Some people claimed it was the best they ever smoked.

Two legends were crossed to produce this strain. We combined our famous Warlock-father with our legendary AK-47-mother and the result gave us pure happiness! In fact this hybrid brings happiness TWICE. First you will be happy about how easy to grow she is. Serious Happiness has the perfect hybrid-structure for indoor growing with several side branches not too close together. In flowering each branch grows a very big and dense bud with few leaves, she is easy to manicure! Her aroma and taste are sweet and fruity, sometimes a bit spicy, with a sugary aftertaste when smoked. That is the moment when she gives pure happiness for the second time. Her effect is a longlasting buzz that combines a nice body-stoned with an incredible head-high, we felt this as pure bliss. The name Serious Happiness came up after smoking this fantastic strain, because thats exactly how the grower feels, happy while she grows and seriously happy when she is finished. FIRST award won by Serious Happiness: 3rd prize in the category: 'Sativa / Grower' at the IC-420 Cup 2015 in Amsterdam, entered by CLOUDZ. The yield of this variety is AMAZING! She received the SPECIAL AWARD for the MOST PRODUCTIVE variety at the Master Seedscup 2016 (edition: Outdoor Spain) from YERBA-Magazine.
