KnowTechie and Grenco Science are joining forces to blow your minds with a giveaway so good that you might forget about it (we all know how marijuana affects short-term memory)!
We’re about to elevate your world with some of the most innovative creations in the cannabis industry. From the state-of-the-art Stündenglass Gravity Infuser and the versatile G Pen Hyer to the compact Dash+ portable Vape – you could win the opportunity to experience cannabis like never before.
Sure, you may have smoked out of a vape before, and that’s cool and all. But have you ever smoked out of a free vape? I swear, whatever it is you pack these with, how much better will it taste knowing that it was free?
Anyways, we’re picking three winners for three prizes. Here’s how it works:
Our grand prize promises to deliver an extraordinary experience. The Stündenglass Gravity Infuser is no ordinary bong or hookah.
Remember that plastic water bong you had back in high school? Imagine that old bong reinvented with a touch of genius—as if our science teacher engineered it themselves.
The Stündenglass combines a visually captivating design with functionality that enhances the user's experience through a unique gravity-driven infusion method.
- Simple to use, especially if you have any previous experience with gravity bongs
- Zero-Contact Smoking
- Lung-busting results
- Multiple different use-cases besides smoking cannabis
- It's outrageously expensive
- Cleaning the Stündenglass can be a little tricky
Second Place: G Pen Hyer
Then we have the G Pen Hyer, standing tall as our runner-up prize. Compact yet mighty, this email is designed to seamlessly work with concentrates or dried herbs, offering a vaping experience unlike any other.
Add a touch of personality with the unique Tyson 2.0 x G Pen Hyer Vaporizer, expanding your possibilities for customization.
And let’s not forget our third-place prize, the Dash+ Vape. Discreet, lightweight, and designed for absolute convenience, it’s a game-changing device from the renowned DashVapes line.
Fusing the power of a desktop rig with the convenience of a portable e-nail, G Pen’s Hyer packs a powerful punch you can easily enjoy anywhere. And yes, it rips fat clouds.
Third Place: Dash+
Entering couldn’t be any easier. All you need to bring to the table is your email address or Facebook login. That’s it! Head over to our giveaway page, and choose the method of entry that works best for you.
But here’s where it gets even better – the more entries you secure, the higher your chances of walking away with one of our top-tier prizes.
That means more ways to experience the cutting-edge technology of the Stündenglass Gravity Infuser, the versatile functionality of the G Pen Hyer, or the discreet convenience of the Dash+ Vape.
The Dash+ is a next-generation portable dry herb vaporizer. It features Hybrid heating technology, precise temperature control, and a full-color LED display.
