Type of Greenhouse Grow Lights Available in the Market

Knowing what kind of greenhouse light you’re looking for will enable you to pick the right product according to your greenhouse size, plant type, and region’s climate. Here are the most common types of greenhouse grow lights available in the US:

  • LED Greenhouse Grow Lights: LED lights are the best kid in the block. Whether you’re looking for household or greenhouse grow lights, EPA suggests you pick LED lights for energy efficiency benefits. LED lights have become the best greenhouse grow light option due to their high performance and wavelength-balancing qualities.

What’s more, LED lights are efficient, affordable, and easy to repair and replace.

Red-green-blue wavelengths

  • HID Bulbs: Short for High-Intensity Density Bulbs, HID lights are another efficient and highly functional option for adding a supplemental light source for your plants. However, using an HID-based greenhouse grow light is a bit complicated. Growers must understand their product’s features really well and install the light at an optimal distance. HID bulbs usually emit higher-intensity wavelengths that can lead to leaf burn.


When and Why You Should Install Greenhouse Grow Lights?

Your primary goal for installing a greenhouse grow light should be to increase light exposure inside a greenhouse. Greenhouse grow lights act as a supplemental light source that can fulfill the spectrum requirements of plants in case of inadequate sunlight availability. In short, plants cannot grow without light, and greenhouse grow lights can help them maintain a steady photosynthesis rate.

However, not all greenhouse grow lights are designed with the same features. Plants contain a unique substance called chlorophyll, which only receives and absorbs a particular wavelength. They react positively to lights falling in the wavelength range of 400-700 nm in the blue and red zones.

It’s also worth noting that plants do not receive green light well and are not able to absorb them deeper into the tissues. Moreover, our greenhouse experts do not recommend gardeners use regular household bulbs as a grow light as they can lead to permanent plant damage by exposing them to a continuous spectrum.

Installing Greenhouse Grow Lights—What’s the Right Distance?

The next question that must be popping up in your mind is, how far a greenhouse grow light should be mounted to ensure safe light absorption? Here’s a short and quick guide according to different grow light intensities:

  • 100 Watt light should be no more than 12 inches away from your plants.
  • Lights emitting up to 399 Watts of power should be 12 to 20 inches away.
  • Light emitting 400 to 600 Watts of power should be at least 30 inches away but no more than 20 inches near plants.
  • For larger greenhouse spaces that do not receive adequate sunlight, you can buy a 600 Watts+ greenhouse grow light but install it over 30 inches away from the plants.
