Manufacturer Information
Genetics & Origin of Watermelon
The starting point for Watermelon was Watermelon OG S1. The breeders at Royal Queen Seeds worked with this prized line until they were able to give it a note of their own – the manufacturer calls the result an even tastier strain with one of the fruitiest profiles in its entire catalogue. Royal Queen Seeds does not reveal which other lines went into it. Genetically, the Indica side predominates with 80% against 20% Sativa. The breeder gives the THC content as 22% and the CBD content as low. The seeds are feminised and photoperiod; flowering therefore only begins when the light cycle is switched. If you would rather grow an autoflowering strain of the same name, you will also find Auto Watermelon by Royal Queen Seeds in our range.
Who Is Watermelon For?
Watermelon is a strain for connoisseurs of fruity aromas. It suits:

Growing Watermelon: Indoor & Outdoor
Indoor Growing
In the tent, according to Royal Queen Seeds, Watermelon reaches a height of 80 to 130 cm and yields 450 to 500 g/m² after 7 to 8 weeks of flowering. The manufacturer recommends techniques such as LST, i.e. tying down the shoots: this keeps the height limited while productivity increases. The flowers form a lot of resin; good air movement and controlled humidity in the final weeks help to bring them to ripeness in good health. Because of the intense terpenes, a carbon filter makes sense. You will find the basics on climate and training in the Growpedia.
Outdoor Growing
In the garden, the plants grow 150 to 200 cm tall. Harvest is in October; as the yield, Royal Queen Seeds states 400 to 500 g per plant, depending on which figure you go by. In the data sheet, the manufacturer assigns the strain to the “short summers” climate. A sunny, wind-sheltered location and supports for heavy side shoots nevertheless make sense. If you need larger quantities of seeds, you will find suitable packs under Bulk Seeds. Only grow where it is legal to do so.
Effect, Aroma & Flavour of Watermelon
The name says it all: according to Royal Queen Seeds, the terpenes of Watermelon taste of watermelon, and the data sheet calls the flavour fruity. The frosty flowers form a lot of resin. The manufacturer does not state a lab terpene profile. It describes the effect as a physical high that leaves you euphoric and blissful and then turns into several hours of couch-lock with increased appetite; the data sheet lists the keywords calming, physically relaxing and sleepy. Royal Queen Seeds therefore recommends the strain for the evening, for example for quiet conversations with friends. With 22% THC, the effect sets in hard and fast, according to the manufacturer. How intense it is depends on dose and individual tolerance.
