An introduction to grow lights

If you’re in an area where it is cloudy and rains all the time, or maybe winter weather is coming and its time to bring the plants indoors. Whatever the situation, your plants, fruits, and vegetables need light!

How do you know what light to use? What can keep my plants warm and alive and still producing while they’re kept in doors?

LED  (Light Emitting Diode) is one of the best options for growing indoors, especially if you have a small set-up. Giant industrial grow operations use High Intensity Discharge lights and we don’t have those here. We’re Apartment Gardens. Our goal is to help you make the most of your small spaces!

 LED lights can cover every color in the spectrum, have a long life and efficiency with a 50,000 hour burn time, and some can emit specific waves. And the best part? These lights do not emit any heat so your plants can be close – or even touching – the LEDs and won’t get burned.

We all know plants need light and water to survive and the sun is the best provider of that light, but sometimes, just like in winter or grey dreary cities, artificial light is all we have.

Light is a type of energy and that level of energy varies depending on the wavelength of the color.

Ultraviolet has the shortest wavelength so it has a higher energy, this is followed by violet, blue, green, yellow, and lastly red which has the longest wavelength and is least energetic.

So here’s the breakdown of those different wavelengths and how they can either benefit or hinder the growth of your beloved plants:


Ultraviolet light –

Also known as UV light and is harmful to humans if we’re exposed to it for too long. Long exposure to plants is also harmful. The less UV light, the better they’ll grow.


Violet light –

It is beneficial to plants. It has a higher amount of energy, it improves the taste of fruits and vegetables, and even increases the antioxidants produced. It helps with plant growth and protects them against damage.

Blue light –

It increases plant growth. It helps seeds germinate and improve growth of roots, stems, and leaves. It’s perfect for seedlings and young plants.

Green Light –

This really doesn’t do much for the plants. It can be used to enhance the production of chlorophyll, which basically makes your plant greener.

Yellow light –

It helps with a plant’s growth and health.

Red light –

It isn’t very effective on its own, but it does help flowers bloom. When it’s combined with the blue light, it helps plants mature and leaf growth increases.

Then there’s also far-red light. The wavelengths are lower than normal red light. Far-red light helps plants produce greater yields by speeding up the process plants usually go through at night.
