Wired through a timer, it opens to let CO2 flow while your lights are on and closes when they switch off. This prevents harmful night-time CO2 build-up, conserves cylinder gas, and keeps daytime levels stable for healthy plant growth. It uses a low-temperature DC design, so it stays cool to the touch and runs near-silently, and it ships with an NZ\/AU wall adapter ready for local outlets.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eChoose your configuration:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eSingle Head.\u003c\/strong\u003e Designed to integrate with a regulator.
