We crossbred an Odl Afghani (Afghanistan Indica heritage) with our Honey rock (Super Widow x Swazi Poison)  and 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.

Sumo Sweet Harlem Diesel Seeds Info

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 strain.

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.

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.

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.

A pungent diesel aroma with a sweet citrus taste is the best way to describe the taste and aroma of the Sweet Harlem diesel.
