Grow Lights For Plants – Why Should We Use them?

Grow Lights for all plants are very useful for indoor gardens that can’t get enough sunlight on their own. Grow lights work very well inside the home by producing light very similar to that of the sun. Your indoor plants will use the light to their advantage in photosynthesis and flourish.

People love growing plants indoors but at times they can be restricted with limited space. We may eventually find the perfect spot inside for our indoor garden although our chosen space may not give enough light. By using grow lights, this will assist with a massive boost of growth. 

Everyone has their favorite plants and if you enjoy growing orchids all-year-round or just looking to start your baby seedlings before placing them outside, then these lights are the ideal solution. It’s convenient to have an ongoing supply of your favorite flowers, herbs and veggies readily available, especially during the colder months of the year.


What are the colours that grow lights produce?

The most popular lights for growing plants that are used are the ones that produce the colour blue or red light but, the best part is that each particular colour can be strategically used for different stages of growth. 

The blue colour light enhances growth to your plants and perfect for starting baby seedlings. Once your plants are more established, the red colour light can be used to assist the plant to become more stocky, as opposed to becoming too tall and spindly.

There are different types of grow lights such as fluorescent, high-density discharge lights, incandescent and they all produce a different colour of light.

  • The cool fluorescent light bulbs have a blue light, whereas the warm fluorescent light bulbs have a red light. A full spectrum fluorescent light bulb will produce red and blue light that will match the requirements for optimum growth. 
  • The incandescent light bulbs produce mostly red light.
  • A metal halide HID bulb produces mostly blue light, whereas the high-pressure sodium HID light bulb produce an orange-red light.
  • Originally, LEDs were limited to red but modern LEDs today can be purchased in either visible, infrared or ultraviolet wavelengths with intense brightness.


What are the best growing conditions for plants?

As we all know, all plants are different and they all need individual growing conditions. They also react to different colours of light and that’s where grow lights for different varieties of plants come into play. Some plants need more light but some only need light for a shorter period of time. For example, flowers such as the African Violet and Begonias enjoy a close source of light for approximately 14 to 18 hours per day at a distance of about 30cm. 

They certainly do enjoy the light and if they can’t get enough, you’ll notice that they will become pale in colour and that isn’t a good sign. The difference with the Ivory and Philodendron plants is that they can be much further away from the light source by approximately 90cm and they only need about 8 to 12 hours of sunlight per day.

Regardless of whether your plants are growing outside or indoors, if a plant doesn’t get the right amount of light it needs, it will not grow. Vegetables grow particularly well in full sunlight, so if you grow your veggies indoors, they will need equally high levels of light to flourish. Plant foliage, on the other hand, can grow in full shade and flourish indoors with much lower light levels.
