Read moreChronic Fast F1 BX regular seeds mark the first release from our exclusive “Be a Breeder” collection. This champion hybrid was created by backcrossing the original Chronic from Serious Seeds with our Chronic Ryder. It inherited the speed, yield quality, and smoke characteristics of its parents.
“Be a Breeder” offers regular strains selected for their stable leading characteristics. These varieties are bred for strong yields and reliable performance and can also be used in breeding projects. With Chronic Fast F1 BX regular seeds and personal support from Doctor’s Choice, you can work toward creating your own autoflowering varieties.
Chronic Fast F1 BX is a fast-flowering photoperiod version of the original Chronic Regular from Serious Seeds. Influenced by its autoflowering ancestry, it can finish 1–2 weeks earlier than the original strain. Flowering takes approximately 8–9 weeks under optimal conditions. Plants begin to show their sex 30–45 days after germination.
Chronic Fast F1 BX is described as a pure F1 heterotic hybrid, combining desirable characteristics from both parents. Its vigor, rapid growth, resistance to bugs and pests, and heavy-yield potential make it particularly suitable for outdoor growing.
Indoors, Chronic Fast F1 BX develops into an average-height plant with a bushy structure, limited side branching, and noticeable stretch. It produces dense, rock-hard buds with a sweet aroma. This stable variety is straightforward to grow and requires no special care. Plant training can help shape its structure, although intensive training may affect the final yield.
Chronic Fast F1 BX regular seeds are intended for growers seeking high-quality, heavy yields. With proper care, plants can produce 500–800 g/m² indoors and up to 1,000 g per plant outdoors under favorable conditions.
Chronic Fast F1 BX develops a recognizable sweet aroma at the beginning of flowering, becoming more intense as harvest approaches. The dried buds combine a light citrus note with a distinctive apricot nuance.
Chronic Fast F1 BX delivers a balanced combination of uplifting and stoned effects. It gradually creates a calm, relaxed atmosphere that can lead into a meditative state lasting for hours.
