Do Greenhouses Use Lights?

We’ll always say that greenhouses can be as simple or complex as you want them to be. Many people just use “cold greenhouses,” which are basic unheated structures, to shelter their plants.

But others go all in when they set up their greenhouse. Some outfit their greenhouses with all kinds of features, including things like shade cloths, air conditioning, and heating.

But do greenhouses use lights, too? In this brief article, we’ll examine the topic of grow lights and the role they can play in greenhouses.

Quick Answer: Do Greenhouses Use Lights?

In short, yes, many greenhouses use lights. The main reason for using greenhouse lighting is that the right kinds of lights can aid plant growth. An extra benefit to lights, though, is that they also provide you ample lighting to see by as you tend to your garden.

The Advantages of Grow Lights

There are tons of different kinds of grow lights for greenhouses. LED lights are perhaps one of the most common. Aside from helping your plants photosynthesize, they can simulate all parts of the light spectrum, they have long life spans, and they’re energy-efficient.

Some greenhouse gardeners choose to use fluorescent lighting instead, though. They’re an affordable alternative, they’re highly energy efficient, and they have a long lifespan.

High pressure sodium lamps are yet another type you could choose. Like the other options out there, they’re energy-efficient and aren’t very large. The downside to them, though, is that they can be expensive to install in your greenhouse.

Regardless of whichever type you choose (if you choose to use greenhouse lighting at all), the main advantage of a grow light is in the name: it assists your plants’ growth.
