Strain Description

Frosted heads covered in trichomes with an intense strawberry aroma and a powerful effect, were our breeding goal for this unique strawberry weed. Of medium size with an abundance of buds and an insane amount of trichomes , it smells of fresh strawberries during flowering.

The perfect combination of great yield and excellent quality. 

Genetics:

Chronic comes from a genetic cross between an AK47, a Northern Light, and a cross between a Northern Light and a Skunk. This strong cross is a variety with mainly Indica origins.

Taste and Aroma: 

Smokers who know and cultivate Chronic choose this plant for its combination of appearance and sweet smell (sweet honey aroma).

With serious and rigorous work you will obtain fabulous flavors that will make the difference with "normal" weed.

Its Cultivation:

The genetics of Chronic produce a medium-sized plant, not too dense, this is the perfect combination of good yield and excellent quality, each grower who cultivates this variety correctly stands with his mouth wide open in front of his plants at harvest time, astonished by the enormous size of the cola and the beauty of the Chronic flowers. 

It grows mainly into a single large central bud that delights the eyes and has few side branches.

Chronic does not respond well to topping, it is better to favor a 'one bud' or a selection of the most beautiful side branches. 

The grower must keep a special eye on the drying process to preserve this sweet honey aroma. Simon gives the following recommendations: "Even when alive, the scent of wildflowers is subtle,  it will be lost for good if not dried properly. When put in plastic before being completely dry, the scent has irreversibly disappeared, this even more so for this variety than for all others I have worked with."

Its Effects:

Chronic fundamentally has a strong effect on the physique but also affects the Mind (a bit relaxing or Carefree and also a hint of meditative or creative effect).

Its kinship with AK-47 brings a long-lasting and appreciated high.

In a few numbers:

Flowering period: 53 to 63 days or 8 to 9 weeks 

It is one of the highest yielding varieties (can reach up to 800g/m2!).

In a few words:

Chronic variety is our most commercial variety, this medium height, not too dense plant, is the perfect combination of very good yield and excellent quality. Smokers who appreciate high quality and who grow themselves choose this plant for its combination of appearance and sweet smell. With its Indica genetic background Chronic weed production can reach 600 g/m2 without losing that special connoisseur feeling.

A bit of history:

Every cannabis seed breeder strives to create the optimal combination of quality, quantity, and potency. A variety that produces heavy flower tops with a delicious smell and tasty aroma that practically drip THC from large amounts of resinous glands. Well, Serious Seeds, for example, is certainly a seed bank that has succeeded in achieving this goal, having selected the famous Chronic variety. With its introduction in 1994, it set a new standard in terms of combining superior yield, flavor, and potency excellence in a single plant. If growing and harvesting were an active part of the screening ceremony of the High Times Cannabis Cup, Chronic would surely have won more than the 3rd place in the hydroelectric category in 1994, when it had been entered in the Cup for the first and only time. Because the buds are not only huge but also almost leafless, beautifully composed of abundant small single flower clusters that add up to big brick-sized colas or even larger.

The pedigree of Chronic is very classic, composed of Northern Lights/Skunk x Northern Lights/AK-47. This is the formula of today's Chronic. The original, which existed in the 90s, did not contain AK. But in the late 90s, Simon, the breeder of Serious Seeds, thought his Chronic was somehow "dated", as he says, and that it needed to be refreshed and made more complex by breeding in a slight degree of new superior genetics. He opted for his proven AK-47. It was of utmost importance to lose none of those wonderful characteristics that had made the variety so popular among growers worldwide. Simon reports: "I bred more sativa into the indica-dominant chronic, which gave it a more complex and full high spectrum without losing the good yield and flavor. The facelift also improved both resistance and resin content. The slightly sweet scent with a bit of piquancy also remained intact."

Chronic - Maybe the fattest bud on earth

Chronic StrainEvery cannabis seed breeder strives to create the optimum combination of quality, quantity and potency. A variety that produces heavyweight flower tops with a delicious smell and tasty aroma that virtually drip THC from vast amounts of resin glands. Well, Serious Seeds for example certainly is a seed bank that has managed to achieve this goal, having bred the famous Chronic strain. With its introduction in 1994, it set a new standard in terms of combining superior yield, flavour and potency excellence in one plant. If growing and harvesting would be an active part of the High Times Cannabis Cup`s testing ceremony, the Chronic strain surely would have gained more than just 3rd place in the hydro category in 1994, when it had been entered in the Cup for the first and only time. Because every grower who properly cultivates this strain stands mouth wide open in front of his plants at harvest time, stunned by the Chronic`s enormous cola size and flower beauty. The buds not only are huge, but also nearly leafless, nicely composed of abundant small single flower clusters that add up to large colas with the size of a brick or even bigger.

The pedigree of chronic is very classic, consisting of Northern Lights / Skunk x Northern Lights / AK-47 strain. This is the formula of today`s Chronic strain. The original one, being in existence during the 90`s, had no AK in it. But by the late 90`s, Simon, the breeder of Serious Seeds, thought that his Chronic was kind of “dated”, as he puts it, and had to be refreshed and made more complex by breeding in a slight degree of superior new genetics. He decided for his proven AK-47. It was of utmost importance not to lose any of those marvellous characteristics that had made the strain so popular amongst worldwide growers. Simon reports: “I bred more sativa into the indica dominant Chronic, which gave it a more complex, full-spectrum high without losing the nice yield and flavor. The facelift also improved both the strength and resin content. The mildly sweet scent with a bit of spiciness also stayed intact.” The grower has to keep a special eye on the drying process in order to preserve this honey-sweet aroma. Simon gives the following recommendations: “Even while living, the wildflower scent is subtle, but it will be lost for good if not dried properly. When put in plastic before completely dry, the scent is irreversibly gone, more so for this variety than for any others I've worked with. But if you let it dry thoroughly, the aroma develops a very strong, sweet smell which doesn't fade. For flavor connoisseurs, this could be the difference between thinking Chronic weed is fabulous or just okay.”

Chronic StrainSo at the beginning of the new millennium, the Chronic strain was reborn and nowadays is stronger than ever, a fact that I recently could convince myself of, having the opportunity to see and shoot splendid specimens of the Chronic weed, grown by “Mr. Power-Planter”. He had sowed five original Chronic seeds, three of which turning out to be female. They were grown on soil in 15 litre pots, watered and fertilized by a drip-feeder system. 33 days after germination, Mr. Power Planter switched the timer to 12 hours light and 12 hours darkness, inducing the plants to enter the flowering stage. What happened very quickly, already within 5-7 days the plants showed their gender. One of the remaining three ladies was pruned for clone production at the main stem so that it grew into a set of strong side branches. While Simon recommends “not to top the plants to encourage multiple big buds, as this strain does not respond well”, this pruned Chronic plant turned out to be a real 102 cm-bomber in the end, exhibiting five tremendous rock-hard top colas and four very well-shaped tops in the lower region of the plant. So at least with this Chronic individual, Simon`s rule was disproved, but this plant probably was an exceptional specimen, with an outstanding hybrid vigour effect. Mr. Power Plant of course was very happy about having selected this especially powerful plant for clone production. The second plant had an impressive top cola and a couple of very well developed side branch colas, reaching 94 cm at harvest time. The third plant measured 80 cm and was not as spectacular as the other ones, but still an excellent indoor plant. Flowering time was 66 days for the “mighty bush”, 68 days for the second and 65 days for the third plant. All of the buds were extremely dense and could very easily be processed at harvest time, as the plants exhibited a high calyx-to-leaf ratio. They were cured and dried very carefully, keeping in mind what Simon had said about the Chronic weed precious, but fragile wildflower scent. When the dry harvest was put on the scales, it was like Eastern and Christmas together for Mr. Power Planter. The multiple top cola bush yielded amazing 85 grams, the second one above-average 58 grams and the third one still respectable 47 grams. Also the aroma, taste and high of the buds fulfilled any expectations, these chunky nuggets were a sweet pleasure to smoke and delivered a long-lasting high that expressed both the sativa and indica spectrum. No wonder that Mr. Power Planter has already started growing the first batch of clones… his new discovery Chronic will keep his garden occupied for a long time, as he said - with a broad smile in his face.

According to Simon, the Chronic strain can also be successfully cultivated under natural light, but has to be grown in a protected environment, e.g. on a sheltered balcony or under glass resp. foil. Ripening time is 15-31 October.
