Grenco Science specializes in portable vaporizers for dry herb and wax, often taking the vape pen form. A pioneer in the vaping industry, Grenco Science was the first vape manufacturer to market the tank system for oil concentrates, as seen in their G Pen Hookah, which would later become the standard method for liquid concentrate consumption. While each Grenco Science vaporizer boasts ease-of-use, vapor production, and ergonomics, Grenco Science has also taken an inspired approach to vape design by collaborating with Snoop Dogg, Phil Frost, Natalie Wood, Pizzanista, and more. Vaping with a Grenco Science vaporizer is not just an activity, but an experience. That's how Grenco Science became a leader in vape pens and portable vapes with their diverse lineup of G Pen vaporizers.

Grenco Science are known for their compact yet powerful portable vaporizers. A Grenco Science vaporizer is characterized by a sleek, smooth design, often with a black rubberized exterior that feels comfortable in your grip and looks elegant. Grenco Science products are designed with convenience and portability in mind. A lineup of portable and pen-style Grenco Science vaporizers make vaping on your feet incredibly easy and gratifying. Ideal for commuters and home users alike, each Grenco Science vaporizer is solid, elegant, and performs like larger vapes at a fraction of the size.

Each Grenco Science Vaporizer has:

Ease-of-Use - Grenco Science knows that easy controls are essential for vaping on-the-go. If you can't quickly choose a temperature and start vaping, you'll miss little opportunities that your busy everyday life affords you, and waste precious time on your lunch break fiddling with your vaporizer interface. Grenco Science vaporizers like the G Pen Elite feature intuitively simple controls that anyone can pick up fast, enabling quick hits on-the-fly and an overall convenient experience. Just a few clicks, and your Grenco Science vaporizer will heat up in seconds.

Portability - Makers of the G Pen know that if you vape outdoors, portability matters. The smaller a vape is, the easier it is to carry, and more discreet it is to use in public. Each Grenco Science vapor epitomizes compactness. The G Pen Elite, for example, is incredibly small and lightweight (albeit it boasts features normally associated with larger vaporizers). Likewise, the G Slim vaporizer, of which there is a wax, dry herb, and oil model, is as slender as an office pen. Grenco Science vaporizers are crafted for commuters who want a stealthy, easy way to take hits during their busy day, or those who seek excellent vapor production from a smaller vape.

Excellent Vapor - Grenco Science vaporizers boast powerful heating systems that defy their compact size. G Pen Elite, for instance, features a ceramic herb chamber and convection heating system that vaporize dry herb without burning it, delivering smooth, flavor-rich hits. Likewise the G Pen Herbal vaporizer has a high quality heating coil that lasts longer and vapes herb efficiently. Grenco Science takes extra care to design vapes that are not just stealthy, but capable of delivering satisfying hits on-the-fly. Expect comfortable, intensely flavored vapor from your Grenco Science vaporizer, without sacrificing portability for vapor quality.


The most popular Grenco Science vaporizer is the G Pen, which comes in a variety of models: G Pen, G Pen Herbal, G Pen Elite, and G Pen MicroG. Like all Grenco Science vaporizers, G Pen units are portable, sleek, and easy-to-operate. Whether you prefer dry herb or wax, there's a G Pen vape for you, and that device will be compact enough to fit in your pocket and hide in your hand. Some G Pen vaporizers, like the G Pen Elite, have temperature controlled batteries with preset temps, others have precision temperature control so your G Pen will pinpoint the perfect temperature for your preferred dry herb strain and vapor profile. The G Pen is one of the most beloved Grenco Science vaporizers because anyone can use it, and for such a compact unit, it does what larger vaporizers do.


G Pen Elite is one of Grenco Science's crowning achievements. Extremely compact, elegantly designed, and intuitively easy-to-use, the G Pen Elite vaporizer does all the essentials--and better than many pricier vapes. While Grenco Science vaporizers like the G Pro and G Pen MicroG have preset temperatures, the G Pen Elite has precision temperature, enabling you to choose with laser accuracy the best temperature for your favorite vapor profile or dry herb strain. G Pen Elite features a ceramic heating chamber that vaporizes dry herb free of combustion. No smokiness. No harsh hits. Just smooth flavorful vapor. The G Pen Elite chamber is also non-stick, leaving little to clean up.

Unlike other portable vaporizers, G Pen Elite is incredibly easy to use. Just click the power button 5 times, then click the "up" or "down" buttons to toggle temperature to the individual degree. The G Pen Elite vape also lets you change between celsius and fahrenheit. Once you've chosen your preferred temp, G Pen Elite will take under 30 seconds to heat up, delivering delicious hits faster than the average vaporizer. The G Pen Elite vaporizer features an exceptionally deep herb chamber that holds up to 0.75 grams. Boasting an LED display, the G Pen Elite is easy to use, and produces vapor quality that defies its compact size.This Grenco Science vaporizer produces some of the best vapor in the industry by virtue of its advanced convection heating system.

The G Pen Elite vaporizer houses a convection heating system, rare among portable vaporizers. This is the secret to the quality vapor created by G Pen Elite. Unlike conduction units, which heat dry herb against the hot surface of the herb chamber, the G Pen Elite vape heats herb using hot air that vaporizes the bowl without burning it. The resulting draws are clean-tasting, comfortable to hit, and very tasty you'd expect from a Grenco Science vaporizer. You won't find many portable vaporizers with vapor productivity like the G Pen Elite, a vape that truly lives up to its name.
