Auto Cinderella Jack won 2nd prize at the Copa Esmeralda in Colombia in 2018.
This Dutch Passion auto has a strong terpene profile. It smells piney, spicy, and fruity. The dominant scent mixes pine and herbs.
Some types also smell fruity and fresh. This positively affects taste and smell. The top four terpenes are alpha-pinene (Pine), beta-myrcene (Floral, earthy, fruity), beta-caryophyllene (Spicy, woody), and limonene (citrus, fresh, fruity).
These terpenes, along with cannabinoids, create a tasty, long-lasting high.
Auto Cinderella Jack produces compact plants and buds that resemble a festive Christmas tree. The plants bloom with beautiful flowers that glisten with crystals. Because of their compact nature, the buds are simple and quick to harvest and trim.
Auto Cinderella Jack reigns as our most potent autoflower strain. It’s the world’s strongest autoflower yet, boasting nearly 26% THC. This fact is backed by two labs using the HPLC method. These autoflower seeds promise an intense high.
Buds are super white and loaded with trichomes, which in turn are packed with THC. In addition to a high THC percentage, this strain also has a very strong terpene profile. This autoflower strain guarantees a unique powerful high with a wonderful aroma and taste.
This project originally started with a crossing of Cinderella 99 and Jack Herer. Using genetics from the “Magnum” line ensures high yields. It boasts over 20% THC consistently, making it potent. Auto Cinderella Jack focuses on increasing THC levels through breeding. Skilled breeders developed this standout strain with precision. The parent genetics are renowned for potency and flavor. Cinderella 99 and Jack Herer are strong strains. Crossing them and adding the Magnum autoflower line produced greatness.
The majority of the plants will be average in height. Exceptions exist, such as a bigger Sativa-dominant type, less dense but yielding more. In addition, there are also special “Christmas tree” phenotypes.
Although some of these plants stay a little smaller, they are fantastic plants to grow. Compact and strong, packed with sticky flowers and a balanced leaf ratio.
Auto Cinderella Jack can be grown indoors, outdoors, or in greenhouses. She performs well under different lights: LED, HPS, or CMH. Also in a micro-culture with energy-saving fluorescent bulbs.
In every grow setup it is possible to achieve top-quality buds and results with this high-performance autoflowering seed variety.
She also does well outdoors and in greenhouses. It is possible to grow her in all climates. Pay extra attention to high humidity.
Because of the compact buds, in some phenotypes, it is important to keep the relative humidity (%RH) as low as possible during flowering. She usually grows into a plant about 0.75-1 meter high, with few exceptions.
The genetics used to grow Auto Cinderella Jack guarantees the following traits:
Auto Cinderella Jack is a top-quality autoflower seed for growers seeking premium cannabis. Its dried buds, with a very high THC level, aren’t ideal for beginners.
Auto Cinderella Jack delivers a potent high with energetic and relaxing effects. It combines an uplifting sensation with a calming body buzz. Some variations lean towards Indica for a mellow experience, while others are more Sativa for a lively effect. Customers describe this hybrid high as a very pleasant high that gives a good punch and can last for a long time.
These marijuana seeds grow from seed to harvest in about 10 to 11 weeks. We suggest growing this strain indoors with a 20/4 light schedule. It’s 20 hours of light and 4 hours of dark. Plants take a break from photosynthesis during the 4-hour dark period. Indoors, it’s best to grow her in a SOG setup. SCROG is possible for experienced growers but not recommended. The plant’s compact nature makes it unsuitable for scroggin. They thrive when grown naturally with fewer plants per m2. Place them in pots from the beginning or after sprouting.
Outdoors and in greenhouses, it may take a little longer to fully mature. Keep in mind that in some circumstances it may take 12 to 13 weeks.
In moderate climates, you can get 2 harvests per season. In places like the Mediterranean, 3 harvests per season are possible. With good planning, it’s achievable.
For optimal outdoor growth in colder, wet regions, start indoors. Pre-grow plants indoors for 1-2.5 weeks under 20/4 light.Preferably in a pot of about 0.5L-1L. This ensures that the plants go outside with a firm root ball and the advantage of a head start. This usually increases the chances of success and yield.
Auto Cinderella Jack produces good yields both indoors and outdoors. Indoors, she can easily yield between 400-500 g/m2. Outdoors, yields of 100-150 grams per plant are fairly easy to achieve. With a good pot, organic soil, nutrition, and sufficient (sun) light, she will provide the grower with a large number of compact buds per plant.
For best results, we recommend growing this strain indoors under LED lights. Preferably using an LED lamp with a controllable spectrum.

It’s possible to use ‘Blue Light Treatment’ post-cultivation for a better terpene profile. However, it’s not a must. Plants may need extra 1-2 weeks beyond flowering time. Harvest it when mature for best quality and yield. Timing varies; inspect with a microscope. Based on the maturity of the trichomes, a decision can be made whether or not to harvest the plant.
One of the strongest THC-rich autos we’ve ever seen! Auto Cinderella Jack® is a feminized autoflower created in partnership with Buddha Seeds, an exceptional autoflower producer from Spain. THC concentration was the only factor considered while selecting the original genotypes. Professional laboratory analysis was performed at every stage of development to confirm that the basic genetics with high THC levels remained constant across multiple generations and in all individual plants.
These autoflowering cannabis seeds are ideal for commercial cultivation for licensed producers and farmers that generate concentrates. Because of its strong cannabinoid and terpene profile, this strain is ideal for producing rosin, BHO, glass, shatter, wax, and other cannabis concentrates.
This high THC autoflower is a cannabis plant that is easy to grow. Every home grower can produce cannabis buds of the highest quality without too much effort. In addition to her strong and potent buds, she also generates good yields. See below some online breeding reports from our customers:
