For basic timing applications, it is hard to go wrong with a regular 120v timer. Timers are essential for managing light cycles, powering hydroponic systems, and powering fans in a day/night cycle. HTG Supply’s selection of 120v timers includes both digital and analog timers to meet …your growing needs. Our digital timers can be programmed down to the minute for precise flood and drain cycles, while our analog timers operate with 15 minute increments, perfect for light cycles. HTG Supply timers are built to handle a full 15A load, and can supply a 1000w grow light with ease.
