An 18″ stemless tube built around four stems feeding a tree perc — the most filtration we put in a straight tube.
The quad stem splits your smoke four ways on the way down, so it hits the water spread out instead of in one column. From there the tree perc stacks bubbles through its arms for a second round of cooling. More surface area, more contact with water, a pull that lands soft at full size.
At 18″ it’s a full-size piece, and the stemless build keeps the diffuser fixed in the tube where it can’t be knocked loose. Runs an 18mm joint and includes an 18mm screen bowl.
✅ Why Choose This Tree Perc Bong?
Full size, fully diffused, smooth the whole way up.
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, so this one sits right at the top of the useful range.
Does a bigger bong hit harder? Bigger doesn’t mean stronger. More volume means cooler, smoother hits but the same amount of smoke spread thinner.
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.
