Auto Cinderella Jack

Auto Cinderella Jack is an award-winning marijuana strain from Dutch Passion that achieves unprecedented THC levels for an autoflowering cannabis plant. Indeed, its THC percentage can reach as high as 26%. This outstanding performance is combined with great growing ease, a considerable yield per plant and a strong but pleasant smell and taste.

What characterises Auto Cinderella Jack cannabis seeds?

Auto Cinderella Jack cannabis seeds have autoflower and feminised characteristics. They grow into plants about one metre tall. The plants develop a compact top with full flower clusters. Those clusters produce weed with a very high THC content, giving an unprecedented high for an autoflower. Cultivation is also very easy for beginners and experienced growers alike.

Genetics of this cannabis strain

Auto Cinderella Jack is a cross of different weed varieties. First, Cinderella 99 was crossed with Jack Herer to create a very potent weed. Then this combination was crossed again with an autoflower from the Magnum line sourced from Buddha Seeds. This gave the plants autoflower properties without sacrificing high and yield.

Yield per plant

The yield per plant differs for this marijuana strain depending on growing method. In particular, the difference between growing indoors and outdoors can be significant. Under LED lights in a professionally managed indoor environment, yields of 400 to 500 grams per square metre can be achieved. Outdoors, yields will be between 100 and 150 grams per plant. In hot climates, by the way, outdoors you can easily achieve two and often even three harvests per year.

Smell and taste of Auto Cinderella Jack

Auto Cinderella Jack has a very strong smell and taste. The largest component of the terpene profile consists of Alpha-Pinene, or pine scent. In addition, you will recognise notes of fruit, spice, wood and citrus. These scents also recur while smoking the weed coming from Auto Cinderella Jack. The spicy and strong combination of scents intensifies the high that will often come in with a big kick.

THC percentage and effect

This cannabis strain has been closely monitored throughout its development to ensure an extremely high THC content. This has done Auto Cinderella Jack no favours, as multiple laboratories have determined the THC percentage to be just over 26%. That is extremely high for an autoflowering cannabis strain. So it goes without saying that this weed will give a strong high that can last a long time.

How do you grow Auto Cinderella Jack cannabis seeds?

Auto Cinderella Jack is an easy-to-grow cannabis strain. Of course, this is mainly due to the plants' auto-flowering properties. In addition, the seeds are feminised so you won't spend time and energy on that either.


The plants thrive under LED lights, growing from seed to harvestable plant in 10 to 11 weeks. Generally, a 20/4 light schedule is used for this, or 20 hours of light and 4 hours of darkness.

Outdoors, the flowering period can take two to three weeks longer. When growing outdoors, it is also a great option to pre-breed indoors for 1 to 2 weeks first. The plants will then be stronger when they go outdoors.
