Don’t use the wrong light again! A must-read guide to grow lights for growing leafy vegetables in large areas

Posted on Apr 02 , 2024

Walk into any large supermarket and you will see neat rows of leafy green vegetables. They seem to be telling you: "Buy me, healthy and fresh."

But the truth behind it is that these leafy vegetables may have experienced a "luxurious journey" with sufficient light and nutrition before reaching the supermarket shelves.

For farmers who grow leafy vegetables on a large scale commercially, ensuring that each leaf receives uniform and appropriate light is a headache but also a critical challenge.

In the face of discerning consumers and growing market demand, it is obviously not enough to rely on the natural sunlight that God rewards from time to time.

This is why, an LED grow light that can provide a stable light source has become an indispensable role in this productivity competition.

Light requirement analysis of leafy vegetables

Let’s get one thing straight: Although leafy vegetables don’t complain, they do have their own “preferences.” A suitable lighting environment is like finding a suitable stage for their growth, where they can grow and develop freely. Too strong or too weak light will slow down the growth of leafy vegetables.

How to choose the right grow light

When choosing grow lights, we must consider the intensity, spectrum, and energy efficiency of the light.

Light Intensity and PPFD

The ideal photosynthetically active radiation density (PPFD) range for leafy vegetables is 200 to 400 μmol/m²/s. Simply put, it's like setting a comfort zone for your leafy vegetables that won't cause them to get sunburned or "light-starved."

Spectral range

Leafy vegetables have a strong craving for blue light during their growth stage, as it promotes their leaf development. At the same time, red light cannot be ignored. Although it focuses more on flowering and fruits, it is equally important for the growth of leafy vegetables.

For large-scale leafy vegetable cultivation, THEONWGROW grow lights are a choice that cannot be ignored.
