aka King Louis XIII, Louis XIII Kush
The King Louis XIII strain may not be from the same time period as the King of France himself, but it is however just as powerful and mighty. The King Louis strain is an indica-dominant strain that is super high in THC and can really pack a punch. It can make one super euphoric and then sleepy, so it’s best saved for evening usage after the day is out.

Unlike some of his successors who bore the same name, Louis XIII was one of Europe’s most respected monarchs. He was the French king for 33 years in the early 17th century and became ruler at the age of nine after the assassination of his father, Henry IV. After winning numerous battles against the Spanish, Louis was regarded as one of the most powerful men in Europe by 1642.
Alas, he succumbed to tuberculosis at the tender age of 41, 33 years to the day of his father’s death. Like the monarch, the King Louis XIII strain is extremely powerful and commands respect.

King Louis XIII Strain Grow Info
When you have King Louis XIII seeds, you have the option of growing indoors or outdoors. If you have the space and private land, growing outside also means you must live in a sunny and dry climate. We recommend that you try growing other strains first to get experience because this isn’t the easiest to cultivate.

If you grow it outdoors, make sure the daytime temperature is between 68- and 80-degrees Fahrenheit. King Louis XIII will be ready for harvest by the end of September or in the first week or two of October. While flowering time is between 8 and 9 weeks, some growers try and harvest early because it is still an excellent yielder. However, waiting an extra week helps bring out the sweet pine flavor it is best known for.
If you choose to grow this strain indoors, consider a hydroponics setup. King Louis XIII responds well to the Screen of Green (SCROG) or Sea of Green (SOG) methods; especially if you fill your growing space with clones. When you train your plants and force them into flowering a little earlier, you can continually rotate your cannabis garden.
Indoor growing also has the benefit of protecting the plants from harsh weather. King Louis XIII is susceptible to mold from excess humidity outdoors, so be careful. It is a hungry strain so include lots of Nitrogen in the vegetative stage, along with added Phosphorus, Calcium, and Magnesium.
Your outdoor yield should be around 21 ounces per plant. Indoors, it is 18 ounces per square meter planted, but you can boost it by introducing extra carbon dioxide into the grow room.
