About the Grenco Science Collection:

Currently, we offer a complete collection by the brand, please read about it below:

Grenco Science G Pen Connect Wax Vaporizer

- G Pen - comes in all possible versions, such as herbal, wax, oil and Snoop Dogg models, this collection is definitely something to consider. The G Pen Herbal and the Snoop Dogg Herbal vaporizer pens are both designed to be used with aromatic blends. Both models are inexpensive options, but it's important to use caution when vaping with either of the models. This is because the dry herb oven can cause combustion during long sessions where you take many back to back draws. For best results, herbal models should be used for short sessions with breaks in between the draws. But the whole collection started with just the classic G Pen for wax and eventually expanded to include even a complete oil kit. For a full review of the classic G Pen click here.

- Micro G Pen - Grenco Science is known for developing innovative models and making vape pens that are unique and stylish. The Micro G or Micro G Dual are vape pen kits meant for waxy concentrates which are compact and affordable, but smaller in size than the original, making them easier to carry, assemble, load and use. Unfortunately, at this time Micro models are available to be used with thick waxes only.

- G Pro - was introduced as a compact dry herb vaporizer that's larger than the G Pen, but still compact enough to use easily on the go. Larger in size, this model will give you a larger heating chamber and a bigger battery for longer sessions and more usage time on the go. Durable and sophisticated, the G Pro has stainless steel heating chamber. The G Pro Herbal Vaporizer produces pure vapor, which, after its release, started a new standard and consumer expectations of the herbal vaporizer industry. The G Pro is strictly for dry herbs and now includes only one model. For a full review of the G Pro click here.

Conduction vs Convection Vaporizers for Marijuana

- G Pen Elite - Grenco Science has long been a leader in the design of portable vaporizer pens, but their previous models have left something to be desired. The original G Pen is known to burn herbs, and the G Pro lacks many of the features found in other newer portables. For the price that you'll pay for this kit, the G Pen Elite is likely the best vaporizer for dry herbs that money can buy. This unit is great for beginners who want a good experience, but don't want to invest a lot in a first vaporizer, as well as for more experienced vaporists who want a more economical unit. While there are models out there that provide better quality vapor, you'll typically pay $100 more for them. For a full review of the G Pen Elite click here.

When you're shopping, it's important to understand that Grenco Science offers conduction and convection models. Conduction vaporizers heat up herbs, wax, and oil quickly because their heating elements are in direct contact with the material. This means you don't have to wait long to start your session, but it can also mean that there is a risk of your material getting too hot and combusting or burning. This is much more likely to happen if you're using any of the G Pen or G Pro models, except the new Elite models. If you're looking for other convection models that have less risk of combustion, you may want to check out our complete Convection Vaporizers category in the drop down menu above. Usually more expensive than conduction vapes, convection models heat up herbs a little more slowly because they warm the material by passing hot air through it rather than by exposing it to heat directly. The benefit is that the herbs heat up more evenly and are less likely to burn.

Grenco Science G Pen Vaporizers Side by Side

Some Reviews by Our Customers:

By Brad - Grenco really does have some of the most famously used and reliable vapes out there. I have that basic G Pen vaporizer and it is so fun and easy to use. I love how mine looks, and I get compliments on it, even after all this time. It's very sleek and sturdy, which is really important, because I'm a super clumsy guy. I'm also kind of a vape elitist, and personally, I absolutely will not use anything else but this vape pen.

By Joan Dupree - This is such a good warning for anybody who wants to buy Grenco Science. I actually made the mistake of buying one on eBay. The person said they were authorized, and they had good ratings, but when I got mine it didn't seem quite right. It worked fine for a couple of weeks and then I couldn't get the G Pen to work right. I thought maybe it was the battery charger, so I replaced that and nothing. A new battery didn't work either. I called Grenco Science, and they told me I didn't buy through an authorized dealer, so there was nothing they could do. Lesson learned the hard way.
