More about Watermelon Auto

Tropical wonder with a blissful high

Some smokers select their strains purely for their effects, while others focus their choices on taste. Watermelon Automatic meets both conditions, delivering a powerful psychoactive effect alongside a terpene profile that makes your mouth water. This delicious variety casts a tranquil indica blanket over body and mind, producing excellent yields every time.

Embrace the offspring of Tropicanna Cookies and Lemon OG

RQS’ experienced breeders started with the intention of creating a strain that sets the taste buds on fire. To achieve such an enticing terpene profile, they selected two of the most flavorful parent strains available: Tropicanna Cookies and Lemon OG. Both varieties are packed with limonene, myrcene and other fruity and earthy molecules.

After crossing and stabilizing these varieties over several generations, Watermelon Automatic was created with a genetic composition of 75% indica, 20% sativa, and 5% ruderalis. The fast autoflowering strain managed to inherit all the tasty terpenes of its ancestors.

Growing Watermelon Auto

Watermelon Automatic boasts a fast life cycle and a very rewarding harvest. Moreover, she is so compact and stealthy that growers can grow her in tight indoor spaces and hidden outdoor environments.

Indoors, the plants reach a height of 70-110 cm and when they grow of their own free will, they form one large central cola. When subjected to low-stress training, she will grow closer to the ground and form a more uniform and productive canopy. Expect rewarding yields of up to 500g/m² just 8-9 weeks after germination.

Plants grown outdoors reach a slightly taller height of 90-120cm and produce a respectable yield of 100g/plant. They grow well in containers, raised beds, or directly in the ground.

Aroma, Taste and Effects

Although compact and cute, these resinous buds take a heavy hit. A THC content of 20% hits the body with a formidable yet comforting Indica high that soothes the body, mind and spirit. A medium CBD content works in conjunction with the psychotropic cannabinoid to take the edge off the overwhelming effects.

Enjoy this strain in the evening to bask in its pleasant euphoria. When you do, you'll be met with a divine swarm of aromas and flavors, courtesy of a rich and sweet terpene profile. Characteristic scents of watermelon mingle with other tropical fruits and a touch of earth for a well-rounded but undeniably refreshing smoking experience.
