Growonix Electric Shut Off Kit

An essential add-on to almost any water filter system, the Growonix Electric Shut Off Kit automatically controls the on/off cycling of your water supply and high-pressure booster pumps. The kit consists of a float switch and a solenoid valve working in tandem to keep your reservoir or nutrient storage tank at the ideal level — hands-free.

Mount the float switch in your water tank or nutrient storage tank, and install the solenoid valve on the front end of your water filter. When the tank level drops to the desired threshold, the float switch opens the solenoid valve, the booster pump (if installed) powers on, and the water system begins automatically refilling the storage tank. When the tank reaches the set level, the system shuts off — preventing overflow and protecting your pump from running dry.

  • Includes: Float switch + solenoid valve
  • Port Size: 3/4"
  • Function: Automatic water level control and pump cycling
  • Compatible with: Most Growonix water filter systems and high-pressure booster pumps
  • Ideal for: Hydroponic reservoirs, nutrient storage tanks, RO system automation

Frequently Asked Questions

What is the Growonix Electric Shut Off Kit and what does it do?

The Growonix Electric Shut Off Kit is an automation accessory designed to work with Growonix water filter systems and most other water filtration setups. It consists of two components: a float switch and a solenoid valve. The float switch monitors the water level in your reservoir or nutrient storage tank, and the solenoid valve controls the flow of feed water into the filter. When the tank drops below the set level, the float switch triggers the solenoid valve to open and — if installed — activates a high-pressure booster pump to begin refilling. Once the tank reaches the desired level, the system shuts off automatically. This eliminates the need for manual monitoring, prevents overflow, and protects pumps from running dry.

Is the Growonix Electric Shut Off Kit compatible with my water filter or RO system?

The Growonix Electric Shut Off Kit is designed as a universal add-on compatible with most water filter systems, including reverse osmosis (RO) systems and Growonix-branded filtration units. It features 3/4" ports, which is a standard size for most residential and commercial water filtration setups. It is particularly well-suited for hydroponic grows, indoor farms, and greenhouse operations where automated reservoir management is critical. If you are running a high-pressure booster pump alongside your filter, the kit also controls the pump’s on/off cycling, making it a complete automation solution for your water supply system.

How do you install the Growonix Electric Shut Off Kit?

Installation involves two steps. First, mount the float switch inside your water storage tank or nutrient reservoir at the desired minimum water level — this is the trigger point at which the system will begin refilling. Second, install the solenoid valve on the inlet (front end) of your water filter, inline with your feed water supply line. Connect the float switch and solenoid valve electrically according to the included wiring instructions. If you are using a high-pressure booster pump, wire it into the same circuit so it activates when the solenoid opens. No special tools are required beyond standard plumbing and electrical connections. Always follow the manufacturer’s instructions and local electrical codes during installation.

What are the benefits of using an electric shut off kit with a hydroponic or greenhouse water system?

In hydroponic and greenhouse environments, consistent water and nutrient levels are critical to crop health and yield. The Growonix Electric Shut Off Kit automates reservoir refilling, eliminating the risk of human error, overflow, or tanks running dry — all of which can stress or damage crops. By automatically cycling the booster pump on and off based on actual tank levels, the kit also extends pump life by preventing dry-run conditions. For commercial growers managing large reservoirs or multiple grow zones, this level of automation reduces labor, improves consistency, and provides peace of mind that water supply is always managed precisely.
