Why do plants need light?

Light is a plant's lifeblood for health and well-being, we know this because of a term, you might have heard called photosynthesis. Put simply this is light energy that transfers into growth. Different plants need different levels of light on the spectrum depending on their current stage of growth.

 To dive deeper, it is important to understand what is called photosynthetically active radiation (PAR) a mouthful for sure but this term refers to the correct amount of blue and red light a plant needs to thrive.

PAR is defined by the range from 400 to 700 nanometres which are colours visible to the human eye. PAR plays an important role in processes such as flowering and growth etc, these wavelengths play a huge role in a plant's growth and life cycle to support the development of different periods, generally blue light is essential for stem strength and leaf growth and red light are a must for the reproduction of flowering and new seeds are blossoming.

Types of grow lights

There are two main types of grow lights, LED & fluorescent, Other types of lights such as HID and incandescent are rarely used anymore due to better alternatives. So, which one should you go for? The answer is LED. Why? LEDs are generally considered the better option and here is a list of reasons why;

  • They emit the best ranges of wavelengths for plants
  • They promote growth at different periods of development
  • longer-lasting
  • They’re energy-efficient
  • Cost efficient
  • Easy to use
  • Less likely to burn due to low heat emissions

So, what about fluorescent lights? Depending on the type of fluorescent lights you buy, you could be overspending on a light that won't meet your plant's needs and may even break due to poor build. Therefore, it is best to invest in LEDs for long-term smart thinking.  

What to look for when buying a good grow light

  • Energy efficient – when looking for a grow light you should aim to find a light that has a PPF/W of around 1.8 or higher you may be using more energy than necessary, or risking not having enough light intensity for your plant’s growth.
  • Quality materials – go for those that are steady and don’t break easily for long-term satisfaction and plant care.
  • Aesthetic – You can find really beautiful grow lights that can enhance your green indoor garden. There are a range of different grow lights on the market, in different shapes, sizes which emit different colours, make sure yours fits well and looks good in your living or grow area!
  • User-friendly – If you want an easy-going grow light that does a great job at taking care of your plants, you should get a beginner-friendly light that’s low maintenance, taking care of your plant without you ever having to think twice.


Overall grow lights are a great way to boost the health and wellness of your green friends as well as add touches of aesthetic charm to your living space. Avoiding leaf loss and stem thinning can be easily accomplished with grow lights to allow for the full potential of your green indoor garden to prosper and bloom all year round.

If you’ve been thinking about investing in a long-lasting solution to prevent poor plant health, LED lights might just be the best solution for you if you enjoy aesthetics, quick installation, and easy care.
