Chronic Seeds – Cup Classic by Serious Seeds
What is Chronic? Chronic by Serious Seeds is a feminised, photoperiod hybrid with Indica dominance; the breeder does not disclose the exact cross. It flowers for 56 to 63 days, stays medium-sized and, according to the manufacturer, yields up to 600 g/m². A dominant main bud, a sweet, floral scent and a physically relaxing but not too heavy effect are typical. In 1994 Chronic took third place at the High Times Cannabis Cup. The strain suits yield-focused growers who do not want to compromise on aroma – in the High Yield & Short Flowering category. Available in a pack of 6 seeds.

Genetics & Origin of Chronic
According to the strain description, Chronic is one of the commercially most successful strains in the Serious Seeds catalogue. The breeder is tight-lipped about the lineage: the strain description speaks only of an Indica hybrid that is not specified in more detail. The history of the line, by contrast, is known. In 1994 Chronic reached third place at the High Times Cannabis Cup, and in the year 2000 the strain was improved once more. Since then, according to the breeder, it has won several cups in Spain; those named are the La Bella Flor Cup 2003 and the Highlife Cup 2004 in Spain, there also in the hydro category, as well as the El Punto Cup 2005 in the outdoor category. The seeds are feminised and photoperiod. Serious Seeds gives the THC content as high, without a percentage; a CBD value is missing. In our range you will also find Chronic Regular and CBD Chronic from the same breeder.
Who Is Chronic For?
Chronic is designed for a high yield with good aroma. It suits:
- Yield-focused growers aiming for up to 600 g/m²
- Indoor growers who rely on one central main bud rather than many side shoots
- Self-suppliers who would like to harvest after 56 to 63 days of flowering
- Lovers of sweet, floral-fruity aromas
- Consumers looking for a relaxing but not too heavy effect
It is less suitable if you take shortcuts when drying and curing – according to the breeder, the fine aroma is only preserved with gentle processing. You can find more strains under feminised seeds.
Growing Chronic: Indoor & Outdoor
Indoor Growing
Serious Seeds states 56 to 63 days of flowering, a medium height and up to 600 g/m². The plant is medium-sized and not too dense; thanks to the Indica-leaning genetics it usually forms one dominant main bud with few side branches. Topping that encourages several large side shoots is possible but, according to the breeder, can slightly reduce the overall yield – so the strain is intended more for growing with a single main shoot. The sweet, intense smell already develops during flowering, which is why a carbon filter makes sense. So that the aroma is preserved after harvest, the flowers must be dried gently and cured carefully. You keep a large main bud dry with good air movement. The Growpedia offers further basics.
Outdoor Growing
Outdoors, according to Serious Seeds, Chronic ripens in early to mid-October. It thrives particularly well in a mild climate; with suitable care, the breeder calls it suitable for outdoors. Figures for height and yield per plant are missing. A sunny spot sheltered from rain helps to keep the heavy main bud dry in autumn. Only grow where it is legal to do so.
Effect, Aroma & Flavour of Chronic
According to Serious Seeds, Chronic has a sweet and floral scent and tastes fruity and sweetish. The breeder emphasises how much the result depends on processing: the fine aroma shows itself especially with a good cure and is only preserved if drying is gentle. The manufacturer does not give a lab terpene profile. It describes the effect as balanced – physically relaxing but not too heavy. Serious Seeds rates the THC content as high but does not state a percentage, and there is no information on the CBD content; we therefore do not add any values. If you do not yet know the strain, start with a small amount. How strongly you feel the effect depends on dose and personal tolerance.
