Over time, cannabis has become stronger with modern varieties containing much higher levels of THC than popular strains of the sixties and seventies. Potency will always vary according to how the plant is grown and harvested, but some varieties are undoubtedly more powerful than others. So, without further ado, let’s reveal the top ten highest THC strains ever.
Top 10 – Highest THC strains of all time!
- Chiquita Banana
- Godfather OG
- Sirius Black
- Gorilla Glue
- Acapulco Gold
- Granddaddy Purple
- Big Bud
- Pure Power Plant
Chiquita Banana is an Indica/Sativa variety and can be grown indoors (where the female plants will need a flowering time of just under two months), outdoors and in the greenhouse. The strain is THC-dominant and is not available in feminised versions so male plants will need to be either discarded or used to make hash.
The strain features 33% THC, which is over 50% more than most Amsterdam weed. Hybrid type predominantly Sativa, it is known to make people talkative. Chiquita Banana is an award-winning variety, winning the 2014 Santa Cruz Cup, in the Most THC Category, and finishing third in the hybrid category at the Cannabis Cup in Northern California in 2015. Very sweet and fruity, it resembles its cousin Banana Kush, another legendary smoke.

Godfather OG is always included in the lists of the strongest weeds of all time and with good reason. He is a mostly Indica variety native to southern California that can be cultivated indoors (where the plants will take about two months to reach the flowering phase) and outdoors. Godfather OG is a THC dominant strain containing levels of 28 to 34%.
The strain is a short, squat plant with dense buds that turn purple at the end when you can look forward to a heavy yield. Godfather OG is recommended for the treatment of pain and insomnia thanks to its sedative properties.

With a delicious taste, a super-powerful effect and high production levels, the Gelato variety deserves to be in the garden of every cultivator.
On the one hand, the Gelato descends from the famous Thin Mint, a phenotype of the mythical variety Girl Scout Cookies, on the other side, it has all the genes of the Sunset Sherbert. Thanks to these impressive genes, the buds of the Gelato combine berry flavours with mint and citrus nuances, as well as intense and sweet floral aromas.
The effect of Gelato is bright and relaxing at first, then creative and uplifting. Some Gelato weeds contain up to 27% THC, high by any standards.

Why is Sirius Black such an intriguing strain? Is it the fact that it is named after a Harry Potter baddie? Or its THC content that is an impressive 25%? Or its deep purple flowers and enticing aroma?
We think its a combination of all three, added to the fact that its rich flavour of berry and grape make it an enjoyable smoke that induces an uplifting cerebral high that helps to alleviate anxiety, depression and many other ailments.

If you cultivate Gorilla Glue outside, it will be ready for harvest by the beginning of October, its flowering being 56-63 days. The aroma of its flowers will remind you of pine and a citrus flavour with a background of dark chocolate.
This variety is highly recommended for medicinal use, pain relief, relaxation of muscle tension and assistance with sleep disorders.

The origins of Zkittlez are surrounded by mysticism, but despite this, it has made a name for itself among consumers of cannabis for its rich range of fruity and sweet flavours that surprise from the first smoke. Sweet, sticky caramel combines with berries and sweet and sour flavours that astound everyone who tries it.
Zkittlez is a lovely plant to grow with leaves that are a rainbow of colours, hinting at the complex and delicious tropical aromas and flavours which will eventually follow.
Part of the recognition that Zkittlez has obtained is based on its euphoric effect, which leaves the consumer happy, with a completely relaxed body, thanks to high THC levels that range from 20 to 24%.
Outside, Zkittlez grows like a large Indica, with short internodes which help the formation of large dense buds which, with its side branches also filled with flowers, help to obtain a high production with each harvest. Zkittlez can be harvested in 7 weeks, while those who want to get its maximum potential, production and flavour should wait until the end of the 9th week.

The latest version of Acapulco Gold is a well-balanced Sativa/Indica hybrid. It is one of the most iconic strains of weed in the world, thanks in part to its impressively high THC levels of 21% and CBD of 0.7%. It produces large resinous buds with superb red and brown pistils covered with generous quantities of beautiful THC crystals. Its fruity and intense flavour lingers in the mouth. This Sativa-dominant strain induces a lasting, balanced, relaxing and stimulating effect. Acapulco Gold far exceeds the much-touted effects of earlier varieties.
Acapulco Gold flowers after 60 to 70 days and ripens by mid-October if grown outdoors.
