Garden Controls Cycle Timer is an accurate electronic cycle timer for repeating on/off cycles on 120V garden equipment, keeping fans, pumps, foggers, and CO2 generators running on a consistent rhythm. Built as an on/off setting controller, this cycle timer creates a continuous cycle by alternating powered “on” periods with “off” periods. That makes it ideal when you want predictable intervals instead of a single daily start and stop. In grow rooms and indoor gardens, repeatable cycling can support a more stable environment by keeping key equipment operating on a steady schedule, reducing the guesswork and constant manual switching that can throw conditions off balance. This timer includes day, night, or 24-hour operation, giving you a simple way to match cycling to the time of day. A day/night setting can help keep equipment behavior aligned with your room’s lighting period, while 24-hour operation keeps the same repeating on/off cycles around the clock. The design focuses on easy on and off time setting paired with accurate electronic timing, which helps deliver consistent results when timing matters for humidity control, air movement, and other routine environmental tasks. For capability details, the cycle on range is 1–60 minutes and the cycle off range is 1 minute to 12 hours. It is rated for 120V with a 12 amp load capacity, supporting common indoor gardening equipment on standard power. The result is a versatile control unit that suits many day-to-day grow room needs, from cycling ventilation equipment to managing periodic runtime for irrigation-support gear, without adding extra complexity. Garden Controls Cycle Timer is a good fit for growers who want an electronic cycle timer with day, night, or 24-hour operation, easy on and off time setting, and accurate electronic timing for consistent, repeating on/off cycles on 120V equipment.
