Juicy watermelon on the nose, gassy kush underneath, and a body effect far heavier than the fruit would ever suggest.
T.H. Seeds took its WaterMelon line and crossed it with MK-Ultra, the house Cannabis Cup winner built from OG Kush and G13. The idea was to keep the melon and borrow MK-Ultra's weight and yield. On paper the breeder lists it as 60% sativa, but the experience lands much closer to the indica side of that split.
The breeder's description is of spicy, juicy watermelon wrapped in a gassy kush finish, and hash makers report a cool trace of eucalyptus in the resin.
Expect a body-stoned effect, with the limbs sinking while the mind stays calm and settled rather than foggy. The breeder lists appetite, relaxation and relief from everyday aches among the reported effects, which puts it firmly in evening territory.
In the garden it grows tall, bushy and wide at once, a shape the breeder likens to a small tree, and it stretches two to three times after the flip. Topping or multi-topping is the breeder's advice for keeping that frame in check. White resin heads show early in flower, the buds finish dense and trim easily, and the leaf-to-flower ratio makes it a natural hash plant. Breeder figures: 8 to 9 weeks, 450 to 600 g/m² and 120 to 160 cm.
