Manufacturer Information
Genetics & Origin of Auto North Thunderfuck
Behind the striking name is a well-known line: North Thunderfuck Automatic is the autoflowering version that Royal Queen Seeds developed from the original North Thunderfuck; in one heading the breeder speaks of its autoflower version of Matanuska Thunderfuck. According to RQS, the original is popular for its high THC content and its euphoric effect. Thanks to the cross with a Ruderalis plant, the flowers are available considerably faster. The data sheet states 50% Indica, 45% Sativa and 5% Ruderalis. On the THC content the figures differ slightly: the data sheet states 21%, while elsewhere the manufacturer gives 22%; the CBD content is low. The seeds are feminised. You can find more fast, high-yielding autoflowers under High Yield & Short Flowering.
Who Is Auto North Thunderfuck For?
Auto North Thunderfuck is a potent autoflower that we rate for experienced growers. It suits:
- Experienced growers looking for a potent autoflower
- Indoor growers who can control the height with LST
- Outdoor gardeners in regions with long summers
- Fans of citrus, pine and Skunk aromas
- Consumers who appreciate a stimulating high for the morning
We do not recommend it for a first grow, and if you are looking for a purely calming evening strain, you are better served by an Indica. More tried-and-tested autoflowers can be found under Best Autoflowering Seeds.
Growing Auto North Thunderfuck: Indoor & Outdoor
Indoor Growing
In the grow box, Auto North Thunderfuck grows 90 to 140 cm tall according to the data sheet, while elsewhere the manufacturer states 70 to 140 cm. According to Royal Queen Seeds, it can be kept shorter with training techniques such as LST. The yield is 500 to 550 g/m². The flowering phase lasts 8 to 9 weeks; it takes 10 to 12 weeks from germination to harvest – the light cycle does not need to be switched for this. Because of the Skunk note in the aroma, a carbon filter makes sense. You will find the basics on LST and climate in the Growpedia.
Outdoor Growing
Outdoors, the plants grow 120 to 150 cm tall. For the yield per plant, the manufacturer gives two different figures: 90 to 140 g in the data sheet and 140 to 180 g elsewhere – to be on the safe side, reckon with the lower range. The time frame of 10 to 12 weeks from germination applies outdoors too. Royal Queen Seeds names long summers as the climate zone; a sunny, sheltered location fits this. You can find more strains for outdoors under automatic seeds outdoor. Only grow where it is legal to do so.
Effect, Aroma & Flavour of Auto North Thunderfuck
When it comes to potency, Auto North Thunderfuck puts most other autoflowers in the shade, according to Royal Queen Seeds. The manufacturer describes a fast-acting high that stimulates the mind and recommends the strain as a pick-me-up for the morning; the data sheet adds the keywords uplifting and physically relaxing. The lively effect is accompanied by complex citrus, pine and Skunk aromas, and the data sheet sums up the flavour as earthy, lime and Skunk. The manufacturer does not state a lab terpene profile. Depending on the source, the THC content is 21 or 22%, and the CBD content is low. How intense the effect is depends on dose and individual tolerance – at this potency, a cautious start is worthwhile.
