Black Cadillac strain specs
Black Cadillac Auto is thinly documented: its THC, ratio, flavor and effect data come from AllBud, and its parents' traits from SeedFinder and Leafly. No breeder page with tested timing, height or yield could be found, so the grow rows give estimates based on similar autos and say so.

Where does the Black Cadillac strain come from?
Black Cadillac comes from crossing Jack Herer with Black Domina, and the autoflower version adds an unidentified ruderalis line so it flowers by age. Jack Herer is the Sensi Seeds sativa usually traced to Haze, Northern Lights #5 and Shiva Skunk. Black Domina, also from Sensi Seeds, is a roughly 95% indica built from Afghani, Ortega, Northern Lights and Hash Plant, known for black-green leaves and a heavy effect.
Who first made Black Cadillac, and when, is not documented; AllBud lists the strain but names no breeder, and SeedFinder and Leafly have no entry for it. The same Jack Herer × Black Domina pairing sits behind other strains, such as Black Jack, but there is no published proof that Black Cadillac is one of them under a new name.
How does Black Cadillac Auto differ from the photoperiod Black Cadillac?
Black Cadillac Auto flowers on its own after a few weeks, while the original Black Cadillac needs its light cut to 12/12 to bloom. AllBud lists both at 19–23% THC; the auto carries a small ruderalis share, and its user tags lean more energetic and focused, while the photoperiod entry adds a giggly, heavier body calm.
Data is thin. AllBud's Black Cadillac Auto entry has about 22 ratings and no written reviews, so its effect and flavor lists are only a rough guide.
What does Black Cadillac taste like, and what are its effects?
Aroma and flavor
Black Cadillac tastes light and citrusy, with lemon, pine and flowery notes over a woody, spicy base. AllBud also lists a sour edge and a dank, diesel-like smell, and describes the flavor as on the lighter side.
- Lemon
- Pine
- Flowery
- Woody
- Spicy
- Diesel
Terpenes
- Terpinolene
- Leafly's dominant terpene for the Jack Herer parent; fresh, piney
- Myrcene
- Earthy base listed for the Black Domina parent
- Caryophyllene
- Peppery spice reported in both parents
- Pinene
- Pine-forest note shared by both parents
No terpene test of Black Cadillac Auto is published; these come from its parents' Leafly profiles.
Reported effects
Black Cadillac Auto is most often tagged as uplifting, creative and energetic, with users noting focus and motivation that fits daytime. On the photoperiod entry, users describe a quick head rush that later turns into a calmer, heavier body feeling, which likely comes from the Black Domina side.
- Uplifting
- Creative
- Energetic
- Focused
- Motivated
AllBud lists no specific downsides for Black Cadillac, but users note it can make focusing on a conversation harder and bring on sudden giggles; dry mouth is common with most THC strains.
These Black Cadillac effects come from AllBud's user-voted tags for the auto and photoperiod entries, which have few written reviews. Individual reactions differ, and nothing here is medical advice.
How do you grow Black Cadillac seeds?
Black Cadillac autoflower seeds grow like most sativa-leaning autos: plant them in their final pots, keep 18 to 20 hours of light the whole time, train only lightly early on, and judge harvest by trichomes, since no official timeline is published.
- GerminateDays 1–7
Sow Black Cadillac Auto straight into a 10–15 liter pot so the young plant never has to be moved.
- Early growthWeeks 2–4
The Jack Herer side can make Black Cadillac Auto a little stretchy; tie the top down gently instead of topping.
- FlowerFrom about week 4
Black Cadillac Auto begins blooming on its own on the same 18–20 hour light schedule, with no 12/12 stage.
- HarvestEst. 8–10 weeks from seed
This is an estimate from similar Jack Herer × Black Domina autos; harvest when most trichomes turn cloudy.
Grow tips for Black Cadillac Auto
- Keep notes on your timing. Because no breeder publishes a schedule for Black Cadillac Auto, track sprout date and first pistils so the next grow is easier to plan.
- Expect some variation. A sativa Jack Herer parent and an indica Black Domina parent can give Black Cadillac plants of different heights and bud shapes.
- Watch for purple tones. AllBud describes purple undertones in Black Cadillac buds; mild night cooling late in bloom may bring them out more.
- Go easy on nutrients. Autos like Black Cadillac Auto have a short life and small root zone, so start light on feed and increase slowly.
- Control the dank smell. With diesel and lemon aromas listed, Black Cadillac Auto can get noticeable in late bloom; a carbon filter helps indoors.

Great pick if you
- Want an uplifting, creative autoflower for daytime

Think twice if you
- Need a breeder-published schedule, height and yield before you buy
- Want a heavy, sleepy indica effect
- Plan to keep a mother plant and take clones
- Want a strain with a long track record of grow reports

Jonathan Mustela –
It has a powerful scent that is somewhat earthy with a hint of citrus! Every time I use this product, I feel so much ease and happiness! I heartily recommend it! Despite being one of the easiest strains I’ve ever grown, this one is far better than the others! As I harvested it, I got a ton of yields outside—roughly 198 grams! Wonderful! Easily one of the most fun kind to smoke! Very strong strain that grows quickly and strongly.

Excellent germination of seeds. Healthy and vigorious growth with abundant yield. Potent and very satisfying smoke.
