Strain of the Week: March 29 – April 6, 2026

The final week of March carries over into April with a lineup built around color, fruit, and raw power. Grandaddy Purple and Purple Punch deliver deep grape-berry profiles, Pineapple Express brings tropical brightness, and Ghost Train Haze #8 closes the week with a blistering 35% THC. Seven strains that cover the full spectrum of modern cannabis.

Grandaddy Purple

Grandaddy Purple is an indica at 23% THC, crossing Purple Urkle with Big Bud. The flavor is a defining example of the purple cannabis archetype: berry, fruity, sweet, grape, and earthy notes blend into a profile that is rich, smooth, and immediately recognizable.

Originally popularized in the San Francisco Bay Area by breeder Ken Estes, Grandaddy Purple became one of the most iconic indica strains of the 2000s. The effects are deeply relaxing and sedating, ideal for nighttime use, sleep support, and appetite stimulation. The plants produce striking purple and deep violet buds that are as photogenic as they are potent. Big Bud parentage contributes generous yields, making GDP a practical choice for commercial and home growers alike.

Pineapple Express

Pineapple Express from G13 Labs is a 22% THC hybrid crossing Big Bud with Hawaiian Skunk. The flavor is exactly what the name promises: citrus, pineapple, sweet, and tropical notes create a bright, sun-drenched aroma that stands apart from the darker, fuel-heavy strains dominating current markets.

The 2008 film of the same name brought Pineapple Express into mainstream pop culture, but the strain's appeal goes far beyond name recognition. The effects are energizing and uplifting, making it a strong choice for daytime activities, creative projects, and social situations. Hawaiian Skunk ancestry gives it a distinctly tropical terpene signature, while Big Bud genetics ensure solid yields. The plants grow tall and vigorous, preferring outdoor environments or high-ceiling indoor setups.

Rainbow Belts

Rainbow Belts from Archive Seed Bank is a hybrid at 22% THC, crossing Zkittles with MoonBow. The flavor profile mirrors the candy it is named after: fruity, sweet, candy, and lime notes make this one of the most palatable strains in the current market.

Archive Seed Bank is known for producing flavorful, visually striking cultivars, and Rainbow Belts is a prime example. The effects are balanced and pleasant, delivering mild euphoria and relaxation without excessive sedation. The Zkittles parentage contributes the candy-like sweetness, while MoonBow adds structural integrity and resin production. Rainbow Belts has become a popular choice in concentrate production, where its terpene profile translates well into live resin and rosin products.

Tropicana Cherry

Tropicana Cherry from Relentless Genetics is a 20% THC hybrid crossing Tropicana Cookies with Cherry Cookies. The flavor combines berry, citrus, sweet, and tropical notes into a profile that is bright, complex, and layered.

Relentless Genetics built this cross to capture the best of two celebrated cookie lineages. Tropicana Cookies brings citrus-forward terpenes and visually stunning purple and orange bud coloration, while Cherry Cookies adds dark fruit depth and a smooth smoke quality. The effects are moderate and functional, suitable for daytime use. At 20% THC, it offers an accessible potency level that does not overwhelm. The plants produce medium-sized, dense buds with exceptional color variation that makes them popular among craft growers.

Purple Punch

Purple Punch from Barneys Farm is an indica at 21% THC, crossing Granddaddy Purple with Larry OG. The flavor is a fruit-forward dessert blend: berry, sweet, blueberry, grape, and candy notes combine into a smooth, approachable profile.

Purple Punch inherits the grape and berry character of its Granddaddy Purple parent and adds the OG structure and potency from Larry OG. The effects are relaxing and mildly sedating, often described as a comfortable, couch-friendly experience. It is a popular choice for evening use, stress relief, and sleep preparation. The plants display vivid purple coloration, especially when exposed to cooler nighttime temperatures during flowering. Barneys Farm has refined this line for consistent color expression and flavor intensity across phenotypes.

Forbidden Fruit

Forbidden Fruit is an indica at 26% THC, crossing Cherry Pie with Tangie. The terpene profile is exceptionally complex: citrus, cherry, mango, sweet, and tropical notes create a sensory experience that justifies the exotic name. Few strains offer this level of fruit-forward aromatic diversity.

The effects are potent and physically dominant. Forbidden Fruit delivers deep body relaxation with a dreamy, slightly euphoric headspace. At 26% THC, it is best approached with respect. Cherry Pie contributes the stone fruit sweetness, while Tangie adds the citrus brightness that prevents the flavor from becoming one-dimensional. The buds are dense and display a range of green, purple, and orange hues. It is an excellent strain for extraction, producing concentrates with a remarkably preserved fruit terpene profile.

Ghost Train Haze #8

Ghost Train Haze #8 from Rare Dankness is a hybrid testing at a formidable 35% THC, crossing Hells Angel OG with Nevil's Wreck. The flavor features citrus, sweet, and tropical notes, but the real story here is the potency. At 35% THC, this is one of the strongest strains commercially available.

Rare Dankness developed Ghost Train Haze through careful phenotype selection, and the #8 cut became the standard-bearer. The effects are intense and cerebral, delivering a powerful rush of energy and euphoria that can overwhelm inexperienced consumers. Paradoxically, despite its extreme potency, it often produces a clear, functional high in tolerant users. This is a strain reserved for those who have built significant tolerance. Growers should expect a longer flowering period and a plant that demands experienced cultivation techniques, but the reward is exceptional resin production and cannabinoid content that few other strains can match.
