Project 4516 is a modern hybrid strain created through the crossing of Platinum Kush and Grateful Puff. This strain is cultivated both indoors and outdoors with a moderate level of grower expertise required, typically reaching maturity after a 63-day flowering period to produce a high yield. Its influence on the market is evidenced by a robust line of notable offspring, including Blue 16, Blue Soufle, Boston Cream Pie, Bubble Bath, Cappucchino, Crepes, E85, Eastmont, Hectane, Ice Cream Sundae, Kool Whip, and Supersonic.

The cannabinoid profile for this strain is THC-dominant, with 17.3% THC and 0% CBD, supported by a complex terpene profile that begins with limonene, caryophyllene, and humulene as its primary contributors. These are followed by secondary and tertiary notes of beta-pinene, linalool, pinene, myrcene, terpinolene, and bisabolol. This specific terpene sequence defines the sensory experience of Project 4516, anchoring its aromatic and flavor nuances within the diverse chemical array provided by its parents.

Users typically report effects characterized as relaxed, happy, and uplifted. Project 4516 is frequently utilized for its potential to assist with the management of stress, pain, and sleep difficulties. Through its significant list of progeny, the strain continues to function as a foundational genetic component for many modern hybrid developments, reinforcing its utility in contemporary breeding programs.
