King Kong Seeds – Fast High-Yield Strain by Dr. Underground
What is King Kong? King Kong by Dr. Underground is a feminised, photoperiod cannabis strain bred from Ed Rosenthal Super Bud × Chronic reversed. It flowers for just 7 to 8 weeks, grows medium-sized to tall with many side branches and, according to the breeder, yields 700 to 900 g/m². The manufacturer does not state a THC value and gives the potency as high. Aromas of lemon, Skunk and incense and a fast, euphoric effect are typical. Because of its very high yield potential, we rate it as a strain for experienced growers – in the High Yield & Short Flowering category. Available in a pack of 4 seeds.

Manufacturer Information
Genetics & Origin of King Kong
King Kong is created by crossing Ed Rosenthal Super Bud with a selected "Chronic reversed". According to Dr. Underground, this combination leads to fast flowering without losing quality in the process. The result is a vigorously growing plant that quickly develops into a well-branched, medium-sized to tall specimen and forms resinous buds. The breeder gives no information on the Indica/Sativa ratio or on THC and CBD values; the potency is merely described as high. The seeds are feminised and photoperiod, so flowering only begins after the light cycle is switched to 12/12. Dr. Underground sees the strain above all in mass production and commercial cultivation, because it delivers large quantities of high-quality flowers in a short time. From the same breeder, you will also find Auto King Kong in our range.
Who Is King Kong For?
King Kong is designed for speed and quantity. It suits:
- Experienced growers who can reliably bring very high yields to maturity
- Indoor gardeners who want to harvest after 7 to 8 weeks of flowering
- Growers with space for medium-sized to tall, heavily branching plants
- Outdoor gardeners who would like to harvest from late September to early October
- Lovers of citrus, Skunk and incense notes
King Kong is less suitable for a first grow and for small grow cabinets: the very high yield potential demands experience, the heavily branching growth a lot of space. You can find more strains for the grow room under indoor strains.
Growing King Kong: Indoor & Outdoor
Indoor Growing
Dr. Underground calls the flowering time of just 7 to 8 weeks exceptional for such a high-yielding plant; as the indoor yield, the breeder states 700 to 900 g/m². King Kong grows vigorously, becomes medium-sized to tall and branches heavily – the manufacturer gives no figures in centimetres. So plan for enough area per plant and make use of the many side shoots, for example with a net that supports the branches at the same time. The buds are full of resin and smell intense, so a powerful activated carbon filter makes sense. The manufacturer writes that the strain delivers stable results even for inexperienced growers; because of the very high yield potential, we nevertheless rate it as a strain for experienced growers. You will find the basics on climate and training in the Growpedia.
Outdoor Growing
Outdoors, according to the manufacturer, King Kong is ready for harvest from late September to early October. Dr. Underground states up to 1 kg per plant. The plants become medium-sized to tall and very branchy, so they need space and a sunny, sheltered location. You should support heavy side branches in good time. The breeder gives no information on outdoor height in centimetres or on the preferred climate. Only grow where it is legal to do so.
Effect, Aroma & Flavour of King Kong
According to Dr. Underground, the aroma of King Kong is intense and shaped by lemon, Skunk and a hint of incense, i.e. frankincense; in the scent profile the breeder also lists earthy tones. Occasionally, Haze notes can be detected that round off the flavour. The manufacturer does not name individual terpenes or a lab terpene profile. It describes the effect as fast and intense: euphoric, happy and relaxing – it is said to make you forget everyday life. Dr. Underground rates the potency as high, but the strain description does not state a THC value in per cent, and we do not add an estimate here. So approach it with small amounts: how strong the effect is depends on dose and personal tolerance.
