If you’re interested in indoor gardening, you’ve probably heard about Click and Grow. This innovative system makes it easy to grow herbs, vegetables, and even flowers in your home without the need for soil or watering.

However, one question that many people have is how long the Click and Grow light stays on.

In this comprehensive guide, we’ll answer that question and provide you with everything you need to know about using Click and Grow lights.

What is Click and Grow?

Before we dive into the question of how long the Click and Grow light stays on, let’s take a moment to explain what Click and Grow is.

Click and Grow is a company that creates indoor gardening systems that allow you to grow plants without the need for soil, sunlight, or watering.

Instead, their systems use a combination of technology and nutrient-rich soil to provide your plants with everything they need to grow.

How Does Click and Grow Lighting Work?

The Click and Grow system uses LED grow lights to provide the necessary light for plant growth. These lights are specifically designed to emit the wavelengths of light that plants need most, which are typically in the red and blue spectrum.

Click and Grow lights are energy-efficient, and they provide your plants with the right amount of light for optimal growth.

How Long Does Click and Grow Light Stay On?

The answer to this question depends on which Click and Grow system you use. For most systems, the lights are programmed to stay on for 16 hours a day and then turn off for 8 hours.

This mimics the natural light cycle of the sun and provides your plants with the optimal amount of light for growth.

However, some Click and Grow systems allow you to customize the lighting schedule based on the specific needs of your plants. If you have plants that require more or less light, you can adjust the lighting schedule accordingly.

You can do this through the Click and Grow app, which allows you to set custom lighting schedules.

Why is Light Duration Important?

The duration of light exposure is important for plant growth because it affects the photosynthesis process. Photosynthesis is the process by which plants convert light into energy to fuel their growth.

When plants are exposed to light, they use chlorophyll to convert that light into energy, which they use to create food.

If plants are exposed to too little or too much light, the photosynthesis process can be disrupted, which can lead to stunted growth, wilting, or even death.

That’s why it’s important to provide your plants with the right amount of light for their specific needs.

Other Factors That Affect Plant Growth

While light duration is an important factor in plant growth, it’s not the only factor to consider. Here are some other factors that can affect the growth of your plants:

  • Temperature: Most plants grow best in temperatures between 65 and 75 degrees Fahrenheit. If the temperature is too hot or too cold, it can affect the growth of your plants.
  • Humidity: Plants also need a certain level of humidity to thrive. If the air is too dry, it can cause the leaves to dry out and the plant to wilt.
  • Nutrients: Plants need a variety of nutrients to grow, including nitrogen, phosphorus, and potassium. Click and Grow systems are designed to provide your plants with the right nutrients, but it’s still important to monitor the health of your plants and adjust the nutrient levels if necessary.

Do Click and Grow lights produce Heat?

No, Click and Grow lights do not produce heat. This means that you don’t have to worry about your plants getting too hot or burning from the light

Can I turn off the Click and Grow lights?

Yes, you can turn off the Click and Grow lights if necessary. However, it’s important to make sure that your plants are getting the right amount of light for optimal growth.

How do I know if my plants are getting enough light?

One way to tell if your plants are getting enough light is to look at the color of their leaves. If the leaves are a vibrant green, it typically means that the plant is getting enough light. If the leaves are yellow or brown, it may be a sign that the plant isn’t getting enough light.


In conclusion, the length of time that Click and Grow lights stay on is typically 16 hours per day. However, this can be adjusted to meet the specific needs of your plants.

Providing your plants with the right amount of light is crucial for their growth and overall health. However, it’s also important to consider other factors such as temperature, humidity, and nutrients to ensure that your plants thrive.

By following these guidelines and using the Click and Grow system correctly, you can enjoy a successful indoor garden and fresh produce year-round.
