Hydrology9 vs Puffco Proxy

The biggest practical difference is heating approach: Hydrology9 runs conduction while Puffco Proxy runs conduction (3d chamber, heated ceramic side walls). That changes flavor delivery, vapor density, and how the device responds to slow versus fast draws.

Hydrology9 is the cheaper option at $199 compared with $280 for the Puffco Proxy, about $81 less. Live retailer pricing can shift, so confirm before buying.

Puffco Proxy reaches session-ready temperature in ~25 seconds, while the Hydrology9 takes ~1 minute. That's roughly 35 seconds quicker on the Puffco Proxy, which is useful if you want shorter, on-demand sessions.

Hydrology9 uses conduction heating, while the Puffco Proxy uses conduction (3d chamber, heated ceramic side walls). Heating style influences flavor profile, vapor density, and how forgiving the device is to draw technique.

Hydrology9 controls heat with modular - 5 stage, while the Puffco Proxy uses four presets plus custom profiles in the app. Puffco Proxy gives you finer per-degree control.

Puffco Proxy charges over USB-C; the Hydrology9 uses a Micro USB port. USB-C means one fewer cable to keep around if your phone and laptop already use it.
