There's never been an easier or more affordable way to enjoy your favorite herbs on-the-go than with the new G Slim Herbal Vaporizer from Grenco Science. Combining lightweight technology with sleek simplicity, the G Slim provides high-performance functionality in a compact, highly portable design that you can bring with you anywhere. The G Slim is super-simple to use. Just unscrew the mouthpiece, load your finely ground herbs into the heating chamber, replace the mouthpiece, and hold the button to heat as you inhale. Its sleek stature and overall durability make it the G Slim the perfect companion for concerts, camping, ski trips or just running errands around town. Developed by Grenco Science, one of the most trusted names in the industry.

Power for your Pocket

Despite its demure stature, the G Slim Herbal Vaporizer features a ceramic heating chamber which vaporizes your herbs or ground material with stunning efficiency. Ceramic is used for so that it won’t add any flavors to your dry herb. All you’ll tastes is the pure flavor coming from your favorite ground material. The G slim herbal vaporizer uses conduction vaporization to extract the essential effects from your dry herb. Conduction vaporization is a form of vaporization in which the herbs are directly heated by a heating coil, allowing for quick heat up times.

Pen with Potential

While vape pens for wax and oils are much more commonplace, finding a vaporizer for dry herb that’s a good fit can be much more difficult. The problem being that herb being heated in such a small space is likely to combust, negating the positive effects of vaporization. The G Slim herbal Vaporizer offers a dry herb vape experience with the portability and discrete form factor of a pen. Offering the vapor production of a much larger portable vape, the G Slim herbal vape pen from Grenco Science is sure to please all hit-chasers.

Grenco Pens are Synonymous with Performance and the G Slim Herbal Vaporizer is no exception. As one of the originators of the herb vape pen movement, Grenco Science has over a decade of experience in the industry. Through trials and tribulations, they’ve come to a design that works. All Grenco Science vape pens feature 510 threading, making them highly adaptable and easily maintained. An added benefit to the 510 threading of the G Slim Herbal makes replacement parts easy to find.

How to Care for your G Slim Herbal Vaporizer

Regular maintenance and care is paramount to the life and longevity of any portable vaporizer, including the G Slim Herbal Vaporizer. Luckily for the user, the maintenance for the G Slim Herbal Vaporizer is as simple as its operation. To lengthen the life of your G Slim herbal Vaporizer, make sure to keep the atomizer clean. This can be achieved by brushing away any debris from the coil, burning off any sticky residue and using isopropyl alcohol to further clean the ceramic element of the vaporizer. Use a damp cloth to gently wipe down the exterior of the battery and a stiff pad to clean any residue from the threading.

    Not A True Vaporizer but A Good Electric Pipe

    The G Slim is a nice portable electric pipe that allows you to be discreet when it comes to smoking. It gets hot very fast and my advice would be to not fill the chamber with too much dry herb, when you do it makes it almost impossible to heat the herb and the unit clogs, believe me when I tell you this less is more, you really only need a pinch of dried herb for this, and you'll see the difference in the amount of smoke this produces, it's night and day. I do like this and it is a cheap item, but it's not a vaporizer, the herbs you put in this will experience combustion as they are in direct contact with the heating coil so they do burn, if you want a true vaporizer or need to use a vaporizer this is not the product for you, it's effectively an electric pipe but for what it does it is effective. All in all a good item, but not a true Vape.

    Not impressed

    I took a chance with the G pen,although it's looks great and it's discreet, he heating chamber is both fragile and doesn't heat up well consistently, it's not a good value. I'm m a very disappointed and paid for the same unit twice and it has the same problem.

    Not so good

    A disappointment to say the least. Battery life is very short, tricky to turn on, only two draws because the element gets too hot too fast. Best part - it is slim and elegant and easy for on the go.
