What are the ideal greenhouse lights for your indoor gardening? Check out this detailed grow lights guide for the best, well-researched, and proven options.
If I recall well from my 7th-grade science, plants need light to produce food. They do so through photosynthesis, where green plants absorb certain light wavelengths to convert water, CO2, and minerals, into glucose.
Without this process, plants wouldn’t grow, hence the need for enough light.
When growing plants indoors, it might be impossible for the plants to absorb natural sunlight like other plants. This means that they need an alternative source of sun-like light to still grow healthy.
And, that’s where grow lights come to save the day.
But since not every form of light is ideal for your plants, today we take a look at some of the best greenhouse lights that can guarantee optimal growth for your plants.

An Overview of Greenhouse Lights
Artificial grow lights come in various types and wavelengths. Understanding the right greenhouse lights to use for your plants is a critical step toward nurturing healthy indoor plants.
To help you with this, here are some common types of lighting you should know about:
This type of lighting remains one of the cheapest lighting options and is most common in our homes. However, when used in greenhouses, they should be placed at a safe distance from the plants, as they emit significant heat that might damage plants. They are ideal for some plants and are known to last for around 1,000 hours.
Fluorescent bulbs, on the other hand, emit blue light that is known to encourage bushy plant growth. Unlike incandescent lights, they produce less heat and are more energy-efficient. They are the favorite choice for greenhouse gardeners, especially during seeding.
High-Intensity Discharge lights (HID lights)
These types of greenhouse lights are ideal for large greenhouses. The installation for these ones also needs to be at a safe distance as they emit quite significant heat amounts. I found out that HID bulbs are available in two types, the Metal Halide (ideal during flowering and budding) and high-pressure sodium bulbs (ideal for stimulating plant growth).
LED (light-emitting diode) lights
This is the newest greenhouse light technology we have around. We can call it “the new kid on the block.” LEDs are more energy-efficient, perform better, and have a longer lifespan than the rest of the squad. Greenhouse LED lights are available in either blue or red colors and produce balanced heating.
With this knowledge, picking the right greenhouse lights for your plants becomes quite easy. And to make it even easier, I have gone ahead and prepared a list of the best lights for the different types of plants we usually grow.

Things to Consider when Buying Lights for a Greenhouse
Type of greenhouse
The size and structure of your greenhouse will determine what kind of grow lights you need. A small personal greenhouse will require different greenhouse lights from a large commercial greenhouse.
For instance, a commercial greenhouse will need to grow lights that can withstand humid, harsh conditions, mostly found in commercial settings.
Since plants need PAR (Photosynthetically Active Radiation) light, you should pick grow lights that are within the right wavelengths. PAR light is within 400 to 700nm.
You should always determine how efficient a product is before buying. This will ensure that you get maximum results without costing you an arm and a leg. Look for grow lights that are highly efficient, and at low energy consumption.
Plants need a certain level of heating, below or beyond which, can be detrimental to the plant. This means that you should always pick a grow light offering the ideal heat dissipation. Some lights will produce too much heat and others too little.
