King Louis XIII: A Royal Treat
A completely unique-looking strain, King Louis seeds grow into bright and beautiful plants. The leaves of this plant are massive, purple and red, and spread out like fingers reaching towards the sky. The leaf structure forms an almost perfect canopy above the lower buds and branches. The top buds, or “crown” of this plant, pun intended, feature a triangle shape with white and amber pistils corkscrewing towards the buds. The very top leaves are multi-colored, including rich greens, reds, browns, and even purple. The harvested nuggets are super dense, highly dank, and delicious. A strong aroma comes with breaking these nuggets apart. If you’re a fan of monster nuggets, then this is a great strain for you. King Louis XIII has won multiple high-profile awards, including the High Times Cannabis Cup, the Farmer’s Cup, and the Blazer’s Cup. While it is uncertain which category the strain won within, this strain certainly boasts a reputation that makes most growers dive in head first.
