About Sweet Diesel Auto

South Africa is really two growing countries, and Sweet Diesel does not behave the same way in both. North and east of the escarpment the rain arrives in summer, so this 14/86 sativa does its flowering while the air is still heavy; in the Western Cape the rain comes in winter, so the same plant ripens through a dry autumn instead. An open sativa canopy is the right structure for a humid coast, which is roughly how Durban Poison ended up the shape it is β€” air moves through the plant instead of sitting in it, and the botrytis pressure that ruins denser cultivars through a KwaZulu-Natal February mostly passes it by. The trade-off is the calendar. A 55-65 days bloom on the Highveld has to start early, which in practice means seedlings out by October, or the closing weeks run into frost. limonene expression is strongest where day-to-night swings exceed 10Β°C, and at altitude that is simply what autumn does.

The Aromatic Three

Leading with Limonene, then Pinene, and Terpinolene underneath.

Sweet Diesel Auto β€” Breeder Information

Royal King Genetics

Recreated and stabilised by Royal King Genetics, the breeding team behind this catalogue. Seed lots are germination-tested before they ship. More on the breeding process and about page.

Breeding Programme
Autoflower Programme β€” five-generation auto trait fixing
Stabilisation Notes β€” What This Means for Your Grow

Sweet Diesel is an autoflowering line that has been progressed through five rounds of Royal King Genetics autoflower stabilisation. The autoflower trait is recessive β€” fixing it takes multi-generation work β€” and at F5 the auto trigger and finish window are welded across the pack.

Breeding Goal

Stabilise the recessive ruderalis trait in Sweet Diesel for uniform auto-trigger.

Selection Focus

Chosen for terpene saturation, sativa vigour and a workable finish time despite long-flowering genetics.

Pollen / Mother Source

Royal King Genetics in-house mother stock β€” pollen taken from a sibling male drawn from the same selected pheno population.
