Watermelon is highly sought after by fans of weed who want a peaceful, euphoric high and a strong stone.
Don't underestimate her, though, because the 22% THC hits hard and fast.

More about Watermelon

What do you look for when looking for a new strain? Are intense, fruity flavours and copious amounts of THC your thing? Then you really should try Watermelon. This indica-dominant strain contains terpenes that induce a wonderful stone. And the huge amount of THC leads to a physical high that rushes through your whole body and creates blissful euphoric feelings.

Prepare for hours of couch lock, a heightened appetite and relaxed muscles after smoking a joint or bowl of this weed. The frosty buds are richly covered in resin and develop 22% THC. And the terpenes taste like, you guessed it, watermelon. Clear your schedule, invite your friends over and get ready for a relaxing evening of great conversation. And if you like to cook with weed, work these buds into sweet dishes for a fruity kick!

Watermelon performs well in both the grow room and the garden. Indoors, the plants reach a height of 80-130cm. They will produce a decent yield of 450-500g/m² in 7-8 weeks. Use techniques such as LST to limit growth and boost productivity. Outdoors, the plants can grow up to 200cm tall. You can harvest in October, with harvest weights ranging from 400-500g/plant.
