Mr. Nice G13 x Hash Plant: The Government Legend
Mr. Nice G13 x Hash Plant: The Government Legend
Strain Overview
Type: 100% Pure Indica
Breeder: Sensi Seeds
Lineage: G13 (The Legendary Clone) x Hash Plant (Afghani Landrace)
Market Status: The "Myth Realized"; In the folklore of cannabis, no story is more famous than that of G13. Rumored to be a super-strain bred by the US government at a research facility in Mississippi during the 1970s, a single clone was allegedly liberated by a technician. That clone eventually made its way to the Netherlands and into the hands of Sensi Seeds. To preserve this genetic gold, Sensi crossed the G13 clone with their finest Hash Plant father. The result was named Mr. Nice in honor of Howard Marks (the famous cannabis smuggler and author). It is a double-Indica powerhouse that offers a rare chance to smoke a piece of conspiracy theory history.
THC Content: 18% – 24% (Heavy & Narcotic)
Dominant Terpenes: Caryophyllene, Myrcene, Humulene, Pinene
Key Effects: Total Body Sedation, "Knockout" Stone, Pain Relief, Euphoric Bliss
If G13 is the ghost story of the cannabis world, Mr. Nice G13 x Hash Plant is the tangible proof.
This strain was created with one goal: to create the ultimate Indica. By combining the mysterious potency of the American G13 with the structural perfection of the Dutch Hash Plant, Sensi Seeds created a cultivar that is arguably the heaviest hitter in their entire catalog. It is named after Howard Marks ("Mr. Nice"), a man who dedicated his life to quality cannabis, and the strain lives up to his high standards. It is dense, dark, and devastatingly strong.
History and Lineage: The Spy and the Smuggler
The lineage of this strain reads like a spy novel.
The Mother (G13): The legend says G13 was "Government Indica Strain 13," bred for maximum potency. The clone that Sensi acquired was famous for its incredible resin production and "hammer-like" stone.
The Father (Hash Plant): To seed the G13 (which was a female clone only), Sensi used their Hash Plant father—a premium Afghan cultivar responsible for producing high-grade hashish.
The Name: Howard Marks, known by his alias "Mr. Nice," was a friend of Sensi Seeds founder Ben Dronkers. Naming this top-tier strain after him was the ultimate tribute to the world's most charming smuggler.
Terpene Profile: Earth, Spice, and Coffee
This is a strain for those who like "Dark" flavors. It has a rich, roasted profile that lacks the sweetness of modern hybrids.
Dominant Terpenes
Caryophyllene (The Spice): The dominant terpene. It provides a sharp black pepper and clove bite that warms the chest.
Myrcene (The Earth): Adds a heavy, damp soil and musk base that signals the sedative effects.
Humulene (The Hops): Contributes a woody, earthy note often associated with beer hops and ginseng.
Flavor Notes:
The Aroma: It is savory and intense. It smells of spicy manure, rich coffee grounds, leather, and wet pine. It is a "serious" smell.
The Smoke: Thick and heavy. It tastes of roasted hashish, bitter chocolate, and spicy wood. It coats the mouth with an oily film, a testament to its resin content.
Strain Effects: The Iron Curtain
Mr. Nice G13 x Hash Plant is not a social strain. It is a "turn off the lights" strain.
The Experience
The Impact: The effects are immediate and physical. It feels like a heavy blanket being dropped on your shoulders.
The Sedation: This is a Double Indica. The G13 adds a raw potency, while the Hash Plant adds a narcotic body load. It is one of the best strains for involuntary naps.
The Euphoria: Despite the heaviness, there is a distinct sense of well-being and happiness (the "Mr. Nice" effect). You feel safe and content.
The Medical: It is highly regarded for treating chronic pain, muscle spasms, and severe insomnia.
Best For: End-of-day use, pain management, deep sleep, and weekends where you have absolutely nothing to do.
Growing Mr. Nice G13 x Hash Plant: The Resinous Rock
This plant is a joy for Indica lovers to grow. It is compact, fast, and unbelievably sticky.
Growth Structure
The Structure: It grows Short and Squat. It is a true Indica bush. The leaves are dark green and very broad.
The Yield: Moderate to High. The buds are incredibly dense. They look like rocks.
The Resin: The trichome production is extreme. The G13 influence covers the buds (and often the fan leaves) in a thick layer of "double" glands. It is a perfect strain for making bubble hash or rosin.
The Time: It finishes flowering in 8 to 9 weeks (60 days).
The Care: It is a hungry plant. It can take high levels of nutrients. However, due to the density of the buds, you must keep humidity low in the final weeks to prevent mold.
Grower’s Tip: This strain is ideal for SOG (Sea of Green). Pack the pots tight and let the main colas develop. The weight of the buds is substantial, but the stems are usually thick enough to hold them without much support.
Final Verdict: The Heavyweight Champion
Mr. Nice G13 x Hash Plant is a strain that demands respect. It combines the myth of the G13 with the reality of the Hash Plant to create a pure Indica that is unrivaled in potency and resin production. It is a fitting tribute to Howard Marks—it is bold, it has a great story, and it delivers exactly what it promises. If you are looking for the ultimate "Nightcap" strain or want to make your own high-grade hash, this is the legend you need in your garden.
