Roots Glass 16″ Stemless 360 Grid Cap Tube

Description

Roots Glass 16″ Stemless 360 Grid Cap Tube

A 16″ stemless straight tube running two stages of grid diffusion — heavy filtration without turning the pull into work.

Smoke hits the gridded stem first and gets pushed through a wall of holes into the water, then climbs into the 360-degree grid cap for a second pass. Two stages, both gridded, so you get fine bubbles and a cool pull instead of one hard rip. The splash guard in the neck keeps the water where it belongs.

The stemless build fixes the diffuser right into the tube — no downstem to knock loose or lose. It runs an 18mm joint and includes an 18mm screen bowl with a horn handle, so you can pull it hot without burning your fingers. An opal sits on top of the grid cap.

Frequently Asked Questions

What size bong should I get? For most smokers, 12-14 inches hits the sweet spot — big enough for smooth pulls, small enough to handle. Over 18 inches starts losing terps to volume. At 16″ this one still rips smooth thanks to the double grid.

Is a stemless bong better than a regular one? Different, not better. Stemless bongs have less drag and look cleaner, but you can’t swap out the diffuser if you want different filtration. Regular downstem bongs are more modular.

What’s the difference between a beaker and a straight tube? Beakers have a flared base that holds more water and gives you slower, thicker hits. Straight tubes pull and clear faster with sharper hits. Comes down to preference — both work great.
