Research as of 11/01/2026

Towards the end of flowering, the colas of Diamond OG become so heavy that one grow description provides for supports for the branches. The strain belongs to the OG Kush family and is listed as a cross of OG Kush and an unknown second strain; the original breeder is regarded as unknown, and its origin is placed in Southern California. Several descriptions emphasize the dense trichome coverage that glitters in the light.

Cultivation:

The strain descriptions give differing figures for flowering time: two state 9 to 10 weeks, two others 8 to 9 weeks. Outdoors, harvest is reached around mid-October according to the grow description mentioned. The same source calls for a warm, dry climate without risk of frost for outdoor cultivation and credits the plant with resistance to common molds and powdery mildew. Another profile likewise names warm, dry conditions and additionally requires constant air movement.

The grow description puts the yield at 18 ounces per square meter indoors, about 510 g when converted, and 16 ounces per plant outdoors, about 454 g. Another profile arrives at 400 to 500 g/m² for indoor cultivation. Difficulty ratings range from easy to medium, and plant height is described as medium to tall. Medium internode spacing, flexible side shoots and a pronounced stretch in the first weeks of flowering are also mentioned.

A grower who by their own account has been growing for 25 years places the original plant, in its growth, among the more sativa-leaning OG Kush forms. They describe it as heavily covered in trichomes and higher-yielding than other OG Kush lines, including Pure Kush. What is in circulation under the name today is not, in their view, identical to this original plant.

Genetics and Origin:

OG Kush is the only named parent; the descriptions list the second parent as unknown, in some cases explicitly as a hybrid. Several strain profiles classify Diamond OG as indica-dominant, whereas one grow description sees it as a balanced hybrid with a slight indica lean. Besides Diamond OG, the name Diamond OG Kush is also in use.

The most concrete account of the origin comes from the grower mentioned: the original Diamond OG was an especially good OG Kush cutting from the San Fernando Valley, grown in Diamond Bar, in indoor setups in private homes in the Los Angeles area. Other accounts place the strain more generally in the Southern California OG scene. There is also a seed line from Premium Cultivars, whose description likewise gives OG Kush and an unnamed second parent.

Diamond OG is documented as a parent of Black Diamond, a cross with Blackberry, and also of Diamond Valley Kush.

Aroma and Flavor:

Pine, earth and wood form the core of the profile in the strain descriptions, joined by sour citrus notes, a spicy diesel note and a sweetish component. In user reports pine appears most often, sometimes together with citrus; one report recalls red berries, another describes an unpleasant, onion-like taste. Strain profiles name pinene as the dominant terpene, followed by myrcene and caryophyllene. Other descriptions put myrcene or limonene first.

THC and CBD Content:

The THC figures vary widely: 17 % is given as a single value and 17 to 22 % as a range, while other profiles put the content clearly higher at 20 to 26 % or 20 to 27 %. CBD is given as 0 %, in other profiles with values up to 1 %. One profile additionally lists 1 % CBN.

Effects:

User reports center on a relaxing, body-focused effect that turns into drowsiness in several reports; euphoria, elevated mood and giddiness are also mentioned. Individual users, by contrast, describe the strain as clear-headed and creative, or as focused, and one as stimulating. Impressions also diverge on potency: one report finds it disappointing compared with other indicas, while others rate it as very strong. Accompanying effects named are dry mouth, dry eyes and dizziness, in isolated cases also headache, paranoia, lingering tiredness and a strong feeling of physical heaviness.
