Project 4516

Project 4516 is an indica-leaning hybrid bred by Oakland's Grandiflora Genetics, commonly attributed to a cross between Gelato 45 and Platinum Puff, itself a cross of Platinum OG and Grateful Puff. The cultivar's numeric name is generally understood as an internal breeding reference rather than a coded message. It typically tests in a mid-to-upper THC range and is noted for dark purple coloration.

Profile

Project 4516 flowers are typically dense and rounded, with dark purple coloration frequently reported across the calyxes, a trait attributed to cooler late-flowering temperatures. Trichome coverage is generally described as heavy, giving cured buds a frosted, resin-rich surface over the dark base color. The aroma commonly combines fuel and sweet notes with a floral undertone, blending traits from both the Gelato and OG-descended sides of its lineage. Flavor on the exhale tends toward sweet and fuel-toned, with a floral, slightly earthy finish. Caryophyllene is among the terpenes most frequently reported as prominent in lab testing, joined by limonene and humulene, a combination commonly cited as the source of its fuel-and-floral character.

Reported effects

Consumers commonly report a relaxed, comfortable body sensation paired with a mellow, settled mood shortly after use. Some consumers commonly report a brief uplifted period early in a session before a calmer state takes hold. Reported experiences vary considerably with individual tolerance, dose, and consumption method, and these descriptions do not represent medical or therapeutic claims.

Cultivation notes

Growers typically report a flowering period of roughly 8 to 9 weeks for Project 4516, consistent with its Gelato- and OG-descended background. Plants tend toward a medium height with dense branching, and growers typically report that cooler night temperatures late in flowering help intensify the cultivar's characteristic purple coloration. The strain is commonly grown indoors. Yields are generally described as moderate, with growers typically noting heavy resin coverage even on interior buds.
