The G Pro Herbal Vaporizer is an affordable portable vape enabling discreet dry herb consumption wherever life leads you. Unlike most portable vaporizers, the G Pro vape by Grenco Science features convection heating, delivering clean-tasting, smooth, and flavor-rich vapor free of irritants. The G Pro vaporizer features three presets, optimized for the most popular strains of dry herb. A large herb chamber, characteristic of Grenco Science vaporizers, gives you longer sessions with fewer reloads. Similar to its sister vape, the G Pen Elite, the G Pro Herbal Vaporizer combines high quality materials, advanced heating, and intuitive usability to provide a discreet and satisfying vaping experience. G Pro is one of the most affordable yet high performance portable vaporizers yet. As a testament to the quality of the G Pro vape, Grenco Science offers a 1-year warranty. 

G Pro


Like the rest of the Grenco Science line of portable vapes, the G Pro Herbal Vaporizer features a powerful battery and heating system. A fast heat up time enables you to take quick hits fast, perfect for enjoying vapor in short windows of opportunity. The smart battery has an auto-shut-off feature that turns the G Pro vape off after three minutes of idleness, preserving battery power and preventing dry herb waste. The G Pro battery powers a convection heating system that delivers excellent vapor quality. When the G Pro battery is fully charged, an LED light will glow green. And when it's time for a charge, it will flash red 4 times. Grenco Science designed the G Pro vape for on-the-go use, making sure that the battery life accomodates a busy lifestyle. Charge time is rapid with the G Pro Herbal vape, and the battery life is long, ensuring the unit can last through your day without requiring a charge. 


G Pro Herbal Vaporizer features a convection heating system, a rarity among portable vaporizers. Rather than combust dry herb directly against a hot surface, the G Pro vape sends hot air flowing through the herb chamber to vaporize its contents free of combustion and irritants. The heated air makes contact with more surface area than a conduction chamber can, which is how the G Pro vape creates milky, comfortable vapor. The stainless steel chamber is low conductivity so it won't get hot and burn your dry herb. Instead, hot air seeps through air holes at the bottom of the chamber, vaporizing dry herb at a sweet spot beneath the point of combustion. The G Pro herb chamber is roughly 0.5 grams, much larger than the usual portable vape. You can enjoy longer sessions without the hassle of reloading frequently. The ample chamber of the G Pro vaporizer, coupled with the advanced convection heating system, makes G Pro the go-to vape for dry herb enthusiasts with busy on-the-go lifestyles.  


The G Pro vape features three optimized heat settings, Low, Medium, and High, with their own color codes reflected in an LED light. Operating the G Pro vaporizer is simple. Just click the power button five times to turn the G Pro Herbal Vaporizer on, then hold the button down for three seconds to cycle through the three heating settings. The color coded presets are as follows: 

Low (320F) = Red

Medium (380F) = Green

High (420F) = Blue 

The G Pro Herbal heat settings are versatile enough to provide the perfect vapor profile, whether you enjoy small, flavor-rich hits on the low settings, medium-sized, mild draws on the middle setting, or big, robust rips on the highest setting.


Like the rest of the Grenco Science line, the G Pro features a slick, compact, and ergonomic design, perfect for vaping on-the-go. The G Pro Herbal vaporizer boasts a rubberized exterior that feels comfortable in your grip, and a simple single button control that lets you toggle temperature and get vaping in just a few clicks. The G Pro vape is super compact, easy to hide in your hand, and won't burden your pocket. Ideal for vaping on your feet, the G Pro vaporizer is the perfect companion for enjoying dry herb in a discreet manner from pretty much anywhere. In addition to the pocket-friendly size of the G Pro, the large chamber ensures you don't have to reload dry herb as often in public, making for a more convenient, stealthy experience. The G Pro Herbal Vaporizer is an incredibly discreet portable vape that enables you to enjoy your favorite strains from almost anywhere. 


The G Pro vaporizer is ideal for dry herb enthusiasts who want to enjoy excellent vapor on their feet. At an affordable price, the G Pro Herbal vaporizer offers much of the same features and performance of pricier vapes at a fraction of the cost. Grenco Science includes everything you need to consume delicious vapor on-the-fly, including a wallet grinder card and a USB charger. G Pro is the ultimate companion for dry herb lovers who want portability and great vapor without breaking the bank. The compact design, easy-to-use single button interface, optimized preset temps, high quality stainless steel chamber, and powerful convection heating system combine to deliver a convenient, enjoyable, and altogether discreet experience.

    G Pen Pro

    Hello. This is the perfect vape for on the go or at home not worrying how much longer the battery will last. this is my 5th portable and I love my G Pen. It feels very solid and it is; Great hits for all. I cannot find a better portable vaporizer for the price. Yes better vapes out there, just not in this price range, if you find one let me know, good luck trying. The only down side is it does get a little hot by mouth piece, still very acceptable. I am not a newbie anymore and I am still learning a lot every day. I have spent 200 dollars each on two vapes which are collecting dust. Stop looking and try this one you will glad you did. Also it is so easy to clean and holds plenty of flower. Go for it and be Happy. I did.

    Best to get something higher quality than this

    The Grenco G Pro herbal vaporizer worked like a charm for the first month. Then the vapor quality got incredibly NASTY and I realized that it was off gassing some burning plastic vapor. Tried time and time again to use my "warranty" with Grenco. Grenco was completely unresponsive and pretty much refused to do anything about it. This product is not worth the money and I will never buy another Grenco product, EVER.

    Good value for price range

    I am satisfied with the G-Pro unit. It is much less harsh. Does not produce a cloud but is effective for administration of the medication. I am completely satisfied. A great vaporizer for its price. Practically no smell since no paper is needed.

    g pro

    Practically no visible vapor even at the highest temperature and takes a lot of effort to get a nice pull. Drag. Not recommended for older people with breathing issues.

    DOA unit, horrible customer service

    Mine arrived dead, and the customer service at Grenco is pretty much non-existent. They wanted me to send it back, wait for them to service it, and then return it. This is for a unit that never worked. Won't ever buy their products again.
