Description

Light is the cue that tells colonized mycelium to stop running and start fruiting — but only if it runs on a consistent daily schedule. The Grower’s Select 24-Hour Heavy-Duty Timer automates that schedule for you: plug in a light, fan, or humidifier and set up to 48 on/off cycles a day, and it repeats the same pattern every 24 hours until you change it.

Why Growers Use This Timer

A grow light is only doing its job if it runs on a schedule mushrooms can rely on. Remembering to flip a switch twice a day gets missed — a timer doesn’t. Set your on/off pattern once in 30-minute increments, up to 48 changes across a 24-hour day, and it keeps running that exact cycle automatically for lights, fans, humidifiers, or any other 110V grow-room equipment.

  1. Plug the timer into a standard 110V outlet.
  2. Plug your light, fan, or humidifier into the timer's outlet.
  3. Program your on/off schedule in 30-minute increments — a 12-hour-on/12-hour-off cycle is standard for most fruiting mushrooms.

Frequently Asked Questions

What can I run with this timer?

Any 110V grow-room equipment that plugs into a standard outlet — grow lights, fans, humidifiers, and similar devices. It's built specifically to automate a fruiting light cycle so you don't have to remember to flip a switch.

What's the shortest cycle I can set?

30-minute increments. You can program up to 48 on/off changes across a full 24-hour day.

What light cycle should I set it to?

For fruiting mushrooms, most growers run a 12-hour-on/12-hour-off cycle to mimic a natural day/night rhythm. Once it's set, the timer repeats it automatically every 24 hours.

Does this work with the Mushroom Lighting Kit or the LED Mushroom Light Bulb?

Yes. Plug either light's socket adapter — or any E26/E27 fixture — into the timer's outlet and it will automate the on/off cycle for your grow. See our Mushroom Lighting Kit and LED Mushroom Light Bulb.
