Having decided to use LED lights to grow lettuce or augment sunlight, you need to know what to look out for before choosing one. Here’s a simple checklist to have at the back of your mind. Don’t forget to grab a suitable grow tent or grow bag if you need one.

Know the light requirements

The primary role of LED lights for growing is to help plants photosynthesize. So, you need to buy one that suits the type of plants you are growing, bearing in mind that different plant species have varying light requirements.

Full-spectrum lights are essential for photosynthesis, but red and blue lights are the most important in this regard.

Lettuce is a low-light plant. Like herbs, they require 25W of light per square feet compared to plants like tomatoes that require at least 50W of light.

Size of your indoor grow area 📏📏

Considerably, the larger the area of your hydroponic growing area, the more LED light you will need to light the plants adequately. Once you know your grow room’s surface area, you can calculate the wattage and number of LED lights to use. Usually, when your grow room’s surface area is large, you need to buy several LED lights so each plant can get enough light. 

The type of LED lights you need 💡💡

When shopping for grow lights for lettuce, you have two options to choose from: the veg & bloom LED lights and the full-spectrum lights. Veg and bloom LED lights are designed for focused lighting – grow systems that have separate areas for growing and flowering plants. 

On the other hand, full-spectrum LED lights are all-round lights that provide ample lighting for plants throughout their life cycle. Most full-spectrum light brands come with programmable settings that allow you to opt for Veg or Bloom light depending on your plant’s light intensity requirement. They also come with timers that allow you to schedule the on and off time of the lights.  

Durability ✅✅

Having reviewed tons of products, we can strongly tell you that a product’s price doesn’t guarantee its quality. Therefore, you need to consider the durability of the grow lights for lettuce you intend to buy. Ensure the LED lights have high-quality construction and meet lettuce’s light requirements. 

Photosynthetically Active Radiation (PAR) ♨️♨️

PAR is any light that is beneficial to plants and an alternative to sunlight. Lettuce requires 400 to 450 nanometers wavelength of light at an intensity of 17 mols/m2/day of PAR. LED Grow lights come with different PAR values that must be evenly distributed among your plants.
