Grow facts
Grow facts come from the breeder first, then seed banks and strain databases. With 2 sources we show the range and the middle; with 3 or more, the range and the median, after leaving out values far from the rest. The breeder's own value is the anchor, unless it is far from every other source (outside their range and more than 20% from their median); then we show the full range and the median of all of them. A fact from a single source is marked "1 source", and a fact no source lists is left out. Yields are converted to one unit: indoor per square meter, outdoor per plant.
CTU writes every profile from these facts; we do not copy other sites' descriptions. Values that are a generic default in the source data are left out. Last checked Oct 21, 2026.

Chemdawg is a legendary hybrid strain with THC levels ranging from 18% to 21%, famed for its distinct chemical-diesel aroma and dense colas. Its genetics stem from mysterious bag seed origins, making it a foundational strain for classics like Sour Diesel and OG Kush. This cultivar thrives both indoors and outdoors but demands attentive nutrient management due to its strong feeding needs. Its moderate flowering period and high resin production distinguish it in cultivation and extraction contexts.
The high from Chemdawg initiates with a euphoric and uplifting cerebral rush that sharpens creativity and focus. This peaks into a relaxed and tingly sensation that balances mental stimulation with a calming body effect. The overall experience is balanced, lasting approximately 2 to 3 hours, suitable for both daytime and early evening use depending on harvest timing.
Upon opening a cured jar of Chemdawg, the aroma bursts with sharp chemical and diesel notes accented by a pungent undertone. The inhale presents a smooth profile with subtle sweetness reminiscent of caramel or coffee, while the exhale intensifies the diesel and chemical essence. The terpene-driven flavor profile matures beautifully with proper curing, enhancing its distinctive pungency and smooth smoke.
Chemdawg displays consistent growth indoors and outdoors but requires careful nutrient management due to its high feeding appetite. Indoors, it responds well to SCROG and LST training methods, which help manage its moderate stretch and maximize light penetration for top colas. Outdoors, it favors dry, warm climates with stable temperatures between 70 deg F and 85 deg F. Maintaining humidity below 50%, especially during late flowering, is critical to prevent mold in its dense buds. Proper airflow and defoliation practices further reduce mold risk. Yield optimization depends on canopy management to ensure light reaches lower nodes, supporting its high yield potential.
Chemdawg's moderate stretch requires early training such as topping or SCROG before flowering to maintain an even canopy, which maximizes light exposure and yield. Its high mold risk demands strict humidity control below 50% in late flower and thorough defoliation to prevent bud rot, especially given the dense colas.
Indoor growers using topping or SCROG will benefit from Chemdawg's strong training response and moderate stretch to optimize canopy and yield. Growers in dry, warm climates will find its outdoor preference aligns well with Mediterranean conditions, making it a reliable choice for those environments. Both profiles should be prepared for attentive nutrient management given its strong feeding habits.
Compared to Sour Diesel, Chemdawg has a similar diesel aroma but offers a more balanced effect combining cerebral and body sensations. Unlike OG Kush, Chemdawg's flowering time is slightly shorter and it demands less advanced grower experience. Chemdawg 4 phenotypes tend to be more indica dominant with denser buds, whereas Chemdawg maintains a hybrid balance with moderate stretch and resin production.
Chemdawg typically has THC levels ranging from 18% to 21%, making it a moderately potent strain suitable for experienced consumers. This THC range contributes to its balanced cerebral and body effects that last 2 to 3 hours.
Chemdawg is a hybrid strain with genetics that balance both indica and sativa traits. This hybrid nature explains its combination of uplifting cerebral effects and relaxing body sensations.
Chemdawg flowers in approximately 7 to 9 weeks, which is a moderate flowering period allowing growers to plan for timely harvests. This timeframe supports its dense bud development and resin production.
Chemdawg is moderately difficult to grow due to its strong nutrient appetite and sensitivity to humidity and mold. However, with proper training methods and environmental control, growers can achieve high yields and quality buds.
Chemdawg offers a sharp chemical and diesel aroma with a smooth, slightly sweet inhalation reminiscent of coffee or caramel. The exhale intensifies the pungent diesel and chemical flavors, making its taste profile distinctive and memorable.
