Watermelon Seeds: A Deeply Stoning Cultivar

What do you look for in a cannabis cultivar?If intense fruity flavors and high quantities of THC pique your interest, then you need to give the Watermelon strain a try. This indica-dominant variety leverages stoning terpenes and huge amounts of THC to exert a physical high that sweeps across the body and leaves users feeling euphoric and blissful.

Genetics of Watermelon: A Descendant of Watermelon OG S1

Where does the Watermelon strain come from? Breeders at Royal Queen Seeds started out with Watermelon OG S1. After tinkering for some time, they managed to achieve their own unique spin on this prized variety. The result? An even tastier cultivar that provides one of the fruitiest profiles in our entire catalog.

Aroma, Flavor, and Effects of the Watermelon Strain

Brace yourself for several hours of couch-lock, increased appetite, and muscle-melting joy after firing up a blunt or bong bowl loaded with these flowers. These frosty buds churn out high volumes of resin containing a THC level of 22% and terpenes that taste like—you guessed it—watermelon. Clear your schedule for the evening, invite your smoking buddies over, and get ready for some relaxation and deep chats. If you’re a budding cannabis chef, make sure to include these flowers in sweet recipes to add a fruity kick.

Growing Characteristics of Watermelon Cannabis Seeds

Watermelon feminized cannabis seeds perform well in both grow tents and out in the garden. Indoor plants reach heights of 80–130cm and produce a respectable 450–500g/m² after a flowering period of 7–8 weeks. Employ techniques such as LST to restrict plant growth while boosting productivity. Grown outdoors, plants reach heights of up to 200cm and offer a return of 400–500g/plant ready to harvest in October.

    Title : Beginner friendly?
    Comment : 3 seeds purchased. 3 seeds started beautifully. 1 seed was placed in damp soil 1/4” deep and kept moist and dark for 2-3 days. 1 seed placed in 3 wet paper towels for 2-3 days between two plates to keep dark. 1 seed, placed in a cup of warm water and covered to prevent any light entering cup. All 3 seeds came to life with very strong looking tap roots! Very impressed by the quality of packaging, discreetness and the clear strong genetics of these seeds. Excited to order more!

    Title : Bought Watermelon photo, got unknown autoflower
    Comment : So bought watermelon photo seeds among others. All doing fine. Except one turned out to be autoflower, not sure if it's watermelon auto or something else. To make a long story short, almost killed her with nitrogen. By the time I figured out it's autoflower, all leaves turned dark green and curled (nitrogen abundance). Bottom line, treated her as photoperiod and somehow she survived. Looking nice despite the curled leaves. Should be ready for harvest in couple of weeks. But I'd like to know what strain I'll be smoking! I'll send pictures if needed.
