Grenco Science has pretty much become a household name within the realm of portable dry herb and wax vapes. As prolific as they are, the price point is also fairly good. They have made it very accessible to the budget vaper. Their solution to this problem comes in the form of the G Pen Nova, a portable and easy to use vape pen that compatible with both dry herbs and wax concentrates. But does the lower price of the G Pen Nova mean a significant drop in performance and vapor quality? Let’s find out. 


Like most devices designed by Grenco Science, the G Pen Nova manages to impress us with its above average build quality. While the Nova isn’t exactly the cream of the crop when it comes to overall build quality and design, actually gripping the device in hand instills a feeling of confidence that most of the budget-priced competition fails to manage. Lastly, we never really experienced any niggling issues or inconsistencies throughout the entire period where we were testing the device.


While the G Pen Nova definitely doesn’t get any awards for innovative design, that doesn’t mean we’re not partial to the practical and straightforward approach towards the aesthetics of the device. The stealthy matte black finish is a great touch especially for those looking for something a bit more low-profile or discreet to vape on. The minimal branding is also well appreciated with a nondescript logo located towards the bottom of the G Pen Nova.

Due to size and price constraints, you’re not going to find a dedicated display on the G Pen Nova, instead what you get is a simple (yet practical) RGB LED indicator highlighting the singular power button which activates the device. Like most vape pens, the LED ring changes color to when the battery is fully charged, or close to depletion and in need of recharging.


One of the most welcome surprises that comes with the G Pen Nova is the inclusion of a genuine quartz bowl partnered with a ceramic heating element at the bottom. Despite the G Pen Nova being a budget device, it somehow manages to outclass its pricier brothers in this department. While the flavor and vapor production of the G Pen Nova doesn’t necessarily outclass that of its competition from other brands, it does manage to outdo the performance of most of its predecessors manufactured by Grenco themselves.

The atomizer found used by the G Pen Nova accommodates both dry herb and wax concentrates although in our experience using the device with the former tends to produce an unsatisfactory and inconsistent vaping experience. By the end of each session, we often discovered that the dry herb inside the chamber wasn’t even evenly vaporized even when we tried our best to pack the bowl properly to allow proper distribution of air and heat throughout the chamber. Vaping with wax concentrates, however, produced much better results as we found that the limited chamber size played a bit better with the more viscous concentrates we had on hand.


One aspect we weren’t that pleased with however is Grenco’s decision to integrate a horrifyingly weak battery into the G Pen Nova. Powered by a mere 300mAh battery, the G Pen Nova can be a bit of a pain to use for longer sessions when away from a charging port for an extended period of time. With this in mind, it’s hard to recommend the G Pen Nova for anything else besides occasional personal use.

How To Use the G Pen Nova

Despite it’s budget origins we appreciated the fact that the G Pen Nova took the time to include a loading tool incorporated to the bottom of the mouthpiece which made things a bit more convenient when reloading the chamber on the fly Aside from serving as a loading tool, it can also used to dab wax concentrates or stir up the dry herb to help any potential hot spots in your chamber.

Setting up the device took close to no time at all. Simply charge the battery up with the included micro USB cable hooked up to any powered USB source and the LED indicator will let you know once the device is fully charged by shining a bright green. The G Pen Nova is easily powered on by a quick five clicks on the power button after which you can toggle between the 3 temperature presets (Blue=Low, Green=Medium, Red=High). After deciding on which temperature preset you’d like to vape on, press the power button twice to initiate the heat up process.

When activated this way, the G Pen Nova will heat up for 15 seconds before shutting off. Alternatively, the device can be used in manual mode by simply holding the power button to initiate heat up. When done vaping, just press the power button another five times to shut it off for safe storage.
