Los Muertos is an indica-leaning hybrid bred by LIT Farms, a California seed company, from a cross of Motorbreath 15 and Project 4516. Detroit brand Hytek selected its keeper plant in-house and grows that cut as premium flower under the Los Muertos name.
The seed line also goes by Dia de Los Muertos. Heritage Seed Bank sells LIT Farms' feminized packs under that longer title, with 10 seeds per pack and an 8–9 week flowering window.
LIT Farms built the seed line
LIT Farms is a California breeder whose catalog leans on hybrids with loud terpene profiles. Black Buffalo Seed Bank carries more than 100 LIT Farms varieties in feminized form, including Cherry Bon Bons, Kool Whip and Crepes.
The company works closely with Grandiflora Genetics, and the Project 4516 line runs through much of that shared catalog. Crepes, for example, pairs Pancakes with Project 4516. Los Muertos uses the same parent on one side and a numbered Motorbreath selection on the other.
Heritage Seed Bank files the release under both its hybrid and indica categories. The pack is listed under SKU LIT-034 and sells for $200, and the three buyers who rated it gave it a perfect 5.0.
Motorbreath 15 brings Chemdog and SFV OG
Motorbreath is a cross of Chemdog and SFV OG Kush. Leafly lists it as a hybrid at 26% THC with limonene as its dominant terpene, and it holds a 4.6 rating across 363 reviews. Leafly also calls it an award-winning cross and flags it for experienced consumers because of its potency.
The number 15 marks the specific Motorbreath plant LIT Farms put into the cross. That choice gives Los Muertos a Chemdog and SFV OG Kush backbone on its first side, while the second side comes from a much newer Gelato-family line.
Project 4516 adds the Grandiflora side
Project 4516 comes out of Grandiflora Genetics and also circulates as Top Secret Project 4516. Leafly traces it to Gelato 45 and Platinum Puff and lists it as a 60/40 indica-leaning hybrid at 23% THC, with limonene leading its terpene profile.
Leafly reviewers point to purple and orange flowers and give Project 4516 a 4.6 rating across 34 ratings. They describe the effect as euphoric and creative, versatile enough for either end of the day.
Hytek's Detroit selection
Hytek is a Detroit cannabis brand that sells premium flower in eighths, half-ounce jars and bulk, plus pre-rolls, hand-rolled joints and rosin in pucks and vapes. Its Lowtek line covers budget-friendly ground flower, and the company runs under the tagline "Walking with Purpose."
Hytek picked Los Muertos from LIT Farms seed and classifies its cut as an indica-leaning hybrid. The flower sits on a menu alongside Gelato 33, Permanent Marker, Versace, Deep Blue Z and Dulce de Uva. Hytek describes the flavor as sweet, spicy and gassy with a creamy diesel exhale.
Dense purple buds and a 4.9 rating
Leafly lists Los Muertos as a Hytek hybrid of Motorbreath × Project 4516, testing at 19–28% THC with caryophyllene as its dominant terpene. The strain holds a 4.9 rating from 10 ratings, and Leafly records Dia de Los Muertos as an alternate name.
Reviewers describe dense, sticky buds with purple hues under a thick coat of trichomes, echoing the purple coloring Leafly reviewers see in Project 4516. Most report feeling happy, euphoric and sleepy, and Hytek itself sums up the strain as a head smacker. Leafly places typical pricing at $10–$15 per gram.
