Project 4516 strain guide
Project 4516 is an indica-leaning hybrid from the Gelato family, usually listed as a cross of Platinum Puff and Gelato 45. People know it for a gassy, fruity smell and a euphoric, giggly feel, and it has become a parent of newer strains like E85 and Bubble Bath. You'll sometimes see it shortened to P4516.
Where does Project 4516 come from?
The cross most often given is Platinum Puff and Gelato 45, one of the numbered selections from the Gelato line. One strain database lists it that way, and a cannabis producer's menu gives Platinum Puff and Gelato without naming the number. The breeder isn't clearly documented in the major strain listings.
What is well recorded is where it went next. Project 4516 is a parent of E85, from Grandiflora Genetics in Oakland, of Bubble Bath from Lit Farms, and of Yahemi. That's a lot of influence for a strain with such a plain, code-like name.
Most sources call it a hybrid that leans toward the indica side, roughly 60/40.
What does Project 4516 smell and taste like?
Project 4516 has two sides. Some people describe it as gassy and sharp, with diesel and even a chemical, ammonia-like note. Others focus on the sweeter side: berry, candy and fruit, with earthy and floral tones underneath. Most batches seem to land somewhere between the two.
One strain database lists limonene as its most common terpene, followed by caryophyllene and pinene. Limonene brings a bright, citrusy lift, caryophyllene a peppery edge and pinene a fresh, piney note. The flavour usually follows the smell: sweet fruit up front with gas on the finish.
Project 4516 effects: what people report
People most often describe Project 4516 as euphoric, giggly and creative. Reviews also mention feeling happy, relaxed and a bit tingly, with a mood lift first and a heavier body feel later, which fits its indica lean.
These are experiences people report, not promises. How it feels depends on the product, how much you have and your own tolerance. Dry mouth is the most common complaint, and some people mention dizziness or feeling anxious.
How strong is Project 4516?
Project 4516 is a high-THC strain. Published listings range from about 23% to 30% THC, and some product reviews quote lab results in the mid 30s. CBD is usually close to zero.
Numbers that high are worth taking seriously. If you're new to it, start with a small amount and wait before having more. The THC on your own label matters more than any listing, and our THCA vs THC guide explains why the number on the package can look higher than you'd expect.
Buying Project 4516 in Canada
Look for it under its full name or as P4516. Because it's often used as a parent, you'll also see it inside other names, so check the label to make sure you're getting Project 4516 itself and not one of its crosses.
You might find it as dried flower, pre-rolls or concentrates. Check the THC and CBD numbers and the packaging date, since fresher flower holds more of its smell.
Project 4516 vs Gelato 45
Gelato 45 is usually named as one of Project 4516's parents, and you can hear the family resemblance. Gelato 45 is sweeter and more dessert-like, with a peppery, piney edge and a relaxed, happy reputation. Project 4516 adds more gas and a sharper, almost chemical side, and it's usually listed a few points higher in THC. People describe both as happy and relaxed, though Project 4516 reads more giggly. If you want classic Gelato sweetness, start with Gelato 45. If you like some fuel with your fruit, try Project 4516.
