Bunkerlinge – Ultra Early Love F7

Aroma and Flavor

The terpene profile of the UEL F7 is fresh and expressive: citrus and grapefruit notes dominate the bouquet, accompanied by floral undertones. The result is a nuanced, light aroma that clearly reflects the line’s Colombian sativa heritage.

Genetics & Origin

Ultra Early Love traces back to the Canadian breeder Reeferman (Charles Scott), who established the original line as an early-pheno selection from his Love Potion #1 seed stock. Love Potion #1 was created by crossing the female G13 indica clone with Santa Marta Colombian Gold, followed by a backcross to the Colombian sativa line. The earliest and most light-sensitive phenotypes within this seed stock were selected as Ultra Early Love – not a separate breeding project, but the most consistent selection for early maturity and climate resilience.

After the line was barely available in Europe for years, it was taken over in 2016 by Belgian breeder Arnold for continuation – in a repro effort the community describes as a rescue operation. The line has since been carried forward by Arnold along with the breeders Archangel, GrowHoe, and Harold. The present F7 generation is the result of this long-running selection work, focused on early maturity, mold resistance, and climate adaptation under Northern European outdoor conditions.

Thanks to its extreme light sensitivity, UEL F7 is one of the earliest-flowering sativa lines available for Central European outdoor cultivation – and at the same time a genetically valuable crossing foundation for your own outdoor sativa projects.

Important Germination Notice – Please Read Carefully

Our seeds are extremely light-sensitive. We therefore strongly recommend germinating them exclusively under the natural light cycle. Even if your fingers are itching to get started in spring – be patient and don’t start the seeds before early May.

For germination, we recommend the following methods:

• Direct sowing: Sow directly at the final outdoor location
• Small greenhouse propagation: On a windowsill (using natural daylight!) or sheltered outdoors

Why Not Indoor Pre-Growing Under Artificial Light?

We strongly advise against any indoor pre-growing under artificial light. The reason lies in the high light sensitivity of our genetics:

• Indoor, seedlings are typically lit on an 18- to 20-hour light cycle
• The natural light cycle, however, has not yet reached its maximum in spring – outdoors, 18 to 20 hours of daylight are never reached
• When plants are moved from the long artificial light cycle into the significantly shorter natural outdoor cycle, they respond to this abrupt shortening by forming flowering hormones

Important to understand: This reaction is not an indication of semi-autoflowering or autoflowering genetics, nor of any such introgression – it is simply the result of the pronounced light sensitivity of our lines. This very sensitivity is the actual goal outdoors: shortly after the longest days of the year (summer solstice), the plants reliably respond to the decreasing day length and initiate flowering.

A plant that already shows flowers in spring, however, will not properly recover from this stress and will stay small – effectively wiping out the entire yield.

If the seeds are instead germinated consistently under the natural light cycle, they develop into vigorous outdoor plants that, with ideal care, easily reach 2 meters – more likely 3 to 4 meters – in height, provided nothing artificially holds them back.

Cultivation

UEL F7 has been selected exclusively for outdoor cultivation and is particularly suited to temperate climate zones. Thanks to their high light sensitivity, the plants typically begin flowering in Central Europe by mid-August at the latest and are ready for harvest from late September to early October. The strain shows adaptable growth and suits both experienced outdoor growers and breeding projects.
