Mr. Nice

Mr Nice – a legendary indica with G13 and Hash Plant genes

Mr Nice is a classic strain selected by Sensi Seeds in the 1990s as a tribute to Howard Marks—the famous activist and smuggler who, in his autobiography “Mr Nice,” described his fight for cannabis legalization. Breeders crossed the secret G13 line—a legend from a government laboratory—with resinous Hash Plant, creating a plant with 80% indica and 20% sativa. This unique marriage of Afghan power and American elegance resulted in strong yet smooth‑feeling flower. Mr Nice took 2nd place at the High Life Cup in 2004 and remains valued by medical and recreational users to this day.

The plant’s structure reveals its indica‑dominant roots: a bushy build, large dark‑green leaves with purple coloration, and dense buds covered in orange hairs. THC content is 13–19%, while CBD stays around 1%. Mr Nice’s aroma combines sweet resin, spicy spices, pine, and fruit—often described as “a walk through an orchard.” The flavor is also sweet and smooth, with noticeable notes of wood and warm spices. Thanks to its gentle terpene profile, Mr Nice works well in the evening: it brings relaxation, reduces stress and pain, and helps you fall asleep without heavy “couch‑lock.” Users appreciate the euphoric opening that quickly transitions into a pleasant state of calm.

This strain flowers fairly quickly for an indica—about 8–9 weeks indoors. In good indoor conditions it easily reaches 500–600 g/m², while in the garden you can harvest up to 700 g from a single plant. It’s suitable for beginner growers because it tolerates mistakes and handles cooler nights well. Its G13 roots make plants resistant to mold and pests; however, due to dense buds it’s worth ensuring good ventilation and avoiding excessive humidity. During flowering, moderate organic feeding and soil pH control in the 6.0–6.5 range are recommended. Thanks to strong side branches, plants respond отлично to LST and SCROG, allowing you to maximize space and lighting.

Mr Nice has also given rise to many variants and crosses. In the official Mr Nice Seed Bank catalog you’ll find, among others, Medicine Man (known as White Rhino) combining White Widow with Afghani, and Critical Mass—a legend for huge yields. The Mr Nice strain is also eagerly used by other breeders as a base for hybrids that retain its gentle body high and sweetish aroma while adding their own notes. By legally growing Mr Nice from seed in Germany, you gain access to genetics that wrote a piece of cannabis history—an excellent option for those seeking a relaxing high, warm flavor, and solid plant resilience.
