Sweet Harlem Diesel
We crossbred an Old Afghani ( Afghanistan Indica heritage) with our Honey rock ( Super Widow x Swazi Poison) we called this offspring Sweet afghani. We then further crossed it with a beautiful Sour diesel to create the Sweet Harlem Diesel. A nice mix of citrus and diesel aroma. A nice hybrid of indica and sativa genetics. You will get the best of both worlds. A great strain to spark your creativity. With a heritage from the United States we couldn’t not mention her origin. So we choose to name her Sweet Harlem Diesel with a slight reference to The Netherlands where we further developed this cannabis strain.

Flowering time and appearance
Not the fastest sativa hybrid cannabis strain in our collection. With a 10 to 11 week indoor flowering period the Sweet Harlem Diesel takes a while to grow. She will produce just a few leaves and several big colas. The buds are sticky with amber crystals. It’s an ideal plant to grow outdoors as she will grow into a 200-230cm outdoor cannabis plant. She will be ready to harvest in the end of October. She is very mold resistant. The pungent odor of the sweet Harlem diesel makes it a good idea to use some odor control.
Yield indoor/outdoor
An average yield between 300-400 g/m2 is possible when growing indoors. Outdoors you can expect a harvest between 450 and 600 gram per plant. Sweet Harlem Diesel thrives in sunny climates. If you want to grow Sweet Harlem Diesel in colder climates we advise to use a greenhouse.
Effect + THC + CBD
Almost a perfect hybrid mix of Indica and Sativa genetics. The effects are more Sativa minded with a clear sativa high with a slight indica body high effect. A medium high THC potency with a low level of CBD. It can be used to relief stress, pain, headaches and depression.
Taste and odor
A pungent diesel aroma with a sweet citrus taste is the best way to describe the taste and aroma of the Sweet Harlem diesel.

Why do we use cartoons for our strains
Diesel is an iconic cannabis variety thought to be a cross between Afghani and Mexican landrace strains. This sativa-leaning strain is reportedly another phenotype of the original Chemdawg 91, though its true origins remain a mystery.
According to Seedism, which carries its own version of Diesel, the strain has an intense aroma of grapefruit and lemon that translates into a fruity flavor with hashish undertones.
