This project originally started with a crossing of Cinderella 99 and Jack Herer. Auto genetics were used from the “Magnum" genetic line, which guarantees above average harvests. With THC levels consistently in excess of 20%, this is one of the most powerful autoflowering cannabis strains available today. Auto Cinderella Jack is the result of many generations of selective breeding focused mainly on one characteristic, the THC percentage. By applying careful breeding techniques (only possible with a skilled master breeder) this strain has become so strong that it stood out from the rest of the competition. The parent genetics of these Auto Cinderella Jack hybrid weed seeds are known for being potent, full of flavour and with great yields. Both Cinderella 99 and Jack Herer are two very strong cannabis strains with an excellent reputation. Crossing these, and then breeding this cross with the Magnum autoflower line from Buddha Seeds has created a truly epic autoflowering cannabis seed variety. Seed to harvest time of around 10-11 weeks.

Cinderella Jack Auto turned out to be a very compact plant, finishing at just 24 cm in height. The yield was 41 grams of dry buds, which is quite decent given the size. The effect is light and uplifting, perfect for work or creative activities. It has a clear sativa dominance, providing a mild and motivating high without couchlock. However, I expected a bit more potency. This could be due to the specific phenotype I got, or perhaps some mistakes in the growing process. Overall, it's a great strain for those who prefer a smooth and functional high, but next time I might try another phenotype or a different strain for a stronger kick.

Since I am a noob in gardening I can't tell exactly whether Cinderella Jack (CJ) is easy or hard to grow. From a beginners point of view I would say the strain performed very well. It was very forgiving and continued growing despite my mistakes like overwatering, underfertilizing, overlighting etc.
I applied LST by bending the main stem down to expose the lower shoots to the light source (though Dutch Passion guys don't recommend this). Since the plant was very bushy the leaves didn't have enough space to grow and prevented the airflow. That's why I had to defoliate quite a lot. I think it is better to let CJ grow naturally.
CJ has a very nice scent of pepper.
I would grow it again.

растение пожелтело полностью, наверное из-за того, что рано начал промывку и перестал давать удобрения. Запах шишек фруктовый, похож на манго или на дыню, эффект сативный удар по голове.

Plants were easy to grow and totally hassle-free. Very strong & compact plants. The buds are impressive in size - big, thick, massive, densely packed, dripping with resin.
When smoked, marijuana has an earthy-birch smell and taste, slightly sour. It has a pleasantly stimulating effect at first. But after the second puff, it already slows down the thoughts a bit, and after the third one, it puts you into deep meditation. Strong stuff, although not as i expected. Nevertheless i like it. It was very pleasant to cultivate and even more to consume.

Buds on both plants grew nice and big and very dense. Mainly ran under my 100w. Stinks of blackcurrant berries
pine and hints of citrus. Buds are dense, loaded with long batches of trichomes and they glisten after their 48hr dark rest. Some of the most pungent bud I've yet to grow that stinks so much coming out of the drying period. Can't wait for the cure.

Wow! My new morning favourite! This baby kicks butt!! It is absolutely delicious and it is very potent.
The plant grew like a champ throughout her life cycle, and the smell that developed in late flowering was extremely sweet.

Amazing yields, this is one monster Auto! She filled up my entire tent with thick, fat colas, that didn't lose a lot of weight or volume drying! So thick infact that I lost one cola to mold, would it not have happened I wouldve broke 300g of pure bud from one plant, great genetics

Dried for 8 days but this was maybe 1 day to much . Buds were a bit too dry but this is no problem . Rh % in the jar is 58 . Buds turned out pretty hard and dense , this girl gave me 102 g of fat tasty smelly buds 😍 . She’s definitely a strong sativa , very strong not for an first time smoker . Taste is earthy with a fruity touch , very tasty love that .

I never expected this strong growth from an autoflower. A bit slow to start, but once she was up to speed there was no stopping her.
Aroma is very sweet with a small sting like urea. Effects happy and balanced. Pretty strong for an auto, but definitely not a jack herer. Dutch passion have created a very good strain here.
