How to grow Sweet Harlem Diesel

Yield 300 – 400 g/m² 
Height 120-150cm Taste
Seb's take
The same Sour Diesel and Sweet Afghani cross, described here as splitting the difference evenly between the two lineages rather than leaning either way. Ten to eleven weeks of flowering produce a few big, amber-crystalled colas on a tall, mould-resistant plant that never quite masters the art of discretion.
Where it comes from
Sumo Seeds crossed Sour Diesel with Sweet Afghani to make Sweet Harlem Diesel, splitting the difference evenly between the two lineages rather than leaning either way. The name carries a story the breeder tells plainly: with a heritage from the United States, they could not omit its origin, so they named her for Harlem with a nod to the Netherlands where they developed her further. A trans-Atlantic pedigree, in other words, and one worn openly on the name.
Nose & flavour
The record does not catalogue the flavours, so the nose is read from the lineage: Sour Diesel lends its unmistakable fuel and sourness, Sweet Afghani a rounder, hash-plant sweetness beneath. Take it as a diesel-forward aroma grounded in Afghani weight, in keeping with the parentage, carried on sticky buds studded with amber crystals. A loud, characterful scent that never quite masters the art of discretion.
The high
The record does not list the effects in detail, but it calls her a great strain to spark the creativity, and the balanced Sour Diesel and Sweet Afghani makeup points to an even hand between head and body. Take it as an engaging, creative character in keeping with the diesel heritage, the Sour Diesel lift tempered by the Afghani's settling weight. Companionable, inventive company rather than a one-sided effect either way.
Growing it
Not the fastest sativa hybrid in the collection, taking 10 to 11 weeks of indoor flowering, around 70 to 77 days, so patience is asked of the grower. She reaches a medium 120 to 150cm indoors and a taller 200 to 230cm outside, producing just a few leaves and several big colas, the buds sticky with amber crystals. She is mould-resistant and an ideal outdoor plant, and the yield is a modest 300 to 400 g/m². A slow but characterful grow that rewards the wait, and never quite learns discretion.
