Who Made This Bong? Intro to GRAV

GRAV is one of the most respected names in the cannabis industry.

Founded back in 2004, GRAV Labs operates in Texas and has earned a big following for its high-quality "specialty scientific glassware." They've produced iconic pieces like the Helix Collection, STAX, and, of course, the Gravitron. ​

What is the Gravitron Gravity Bong?

According to GRAV, the Gravitron is the world's first all-glass gravity bong. It's a send-up to traditional homemade versions crafted from plastic bottles, but it has an innovative design that we think is a far cry from a DIY gravity bong.

Using just gravity and water, it delivers dense, pressurized hits. We had an awesome experience with it overall.

Here's what we like about the GRAV Gravitron.

Design and Build Quality

One of the big standout features of the Gravitron is simply how well-built it is.

Made from thick borosilicate glass, it's designed to hold up against regular use. The most recent version of the bong features glass that's five times thicker than its predecessors.

Plus, the minimalist design, with clear glass and subtle branding, makes the Gravitron an easy bong to display on your favorite shelf.

User Experience

Using the Gravitron is simple and straightforward, even for folks who are entirely new to gravity bongs. Its design guarantees that smoke stays contained in the chamber until you inhale, leading to satisfying hits with minimal waste.

We found hits from the GRAV Gravitron to be flavorful, smooth, and cool.

How To Use the Gravitron: A Quick-Start Guide

Here are the steps that we followed to use the Gravitron for a session:

  1. Fill the Base: Pour water into the outer chamber up to the designated fill line.​

  2. Prepare the Bowl: Pack the 19mm funnel bowl with your preferred ground cannabis.

  3. Assemble: Insert the inner bottle into the water-filled base, ensuring the bowl is securely placed.​

  4. Ignite and Lift: Light the bowl while slowly lifting the inner bottle. As you lift, gravity will draw smoke into the chamber.​

  5. Inhale: Once the chamber is filled with smoke, remove the bowl, place your mouth over the neck, and gently push the bottle back down, forcing the smoke into your lungs.​

This method gets you a dense, pressurized hit with minimal effort. ​

Cleaning and Maintenance

Cleaning the Gravitron is pretty simple, which is another aspect of this bong that we love. Here's the method we used.

  • Disassemble: Separate the inner bottle, bowl, and base.​

  • Rinse: Use warm water to rinse out any residue.

  • Deep Clean: For stubborn buildup, a solution of isopropyl alcohol and coarse salt can be used to scrub the interior surfaces.​

  • Dry: Ensure all components are thoroughly dried before reassembling to prevent any water spots or mold growth.​

Regular cleaning will extend the life of this bong and help you get the best possible flavor from your hits.

Pros and Cons of the GRAV Gravitron: Our Honest Opinion

The GRAV Gravitron is an all-around knockout bong, but it does have a few potential drawbacks. Here are our overall takeaways, both positive and negative:

Pros:

  • Durable Construction: Thick borosilicate glass makes this bong easy to trust. It's a major improvement on DIY hand pipes.

  • Efficient Design: Delivers potent hits with minimal waste.​

  • Aesthetic Appeal: Sleek and minimalist design makes the bong display-worthy.

  • Easy Maintenance: Simple to disassemble and clean.​

Cons:

  • Fragility: Despite being well-built and durable, it's still glass. If you're worried about a drop, silicone might be a better option.

  • Learning Curve: If you're unfamiliar with gravity bongs you will find that there's more of a learning curve here than using a regular bong.

The Bottom Line: The Best Gravity Bong We've Tried

The Grav Labs Gravitron Gravity Bong has rightfully earned its place as a Mood staff favorite. It's built exceptionally well, looks great, and delivers some of the coolest, smoothest hits we've ever gotten from any bong. We recommend pairing any bong from the Gravitron product line with your favorite flower from the Mood Shop.
