Or your plants love more hours of sunlight. Whether you are growing some fresh herbs for your meals, or you are fan of exotic and rare plants, using LED grow lights will help them to be healthier, and greener. 

Before you buy your LED grow lights it is important to understand your plant needs, and of course to choose the spectrum that is suitable for your gardening goals, and needs. 


Choosing the Right LED Grow Lights

It is good to make a clear plan before you buy your led grow lights. Think about what kind of plants you are planning to grow.

Are you going to go through the seedling process, or you want to boost the plants you already have. How tall the plants will grow, in order to get  LED lights that are not too short for them.

Where will you place the plants and do you require your LED growing light to be mobile? 


What Color LED Grow Lights Should You Get?

Natural sunlight contains a spectrum that makes the plants grow, blooming, and produce fruits.

Here is why they need a specific color of this light spectrum on their different stages of growth. Plants absorb mainly red and blue light.

Here comes the first advantage of LED light, it has the ability to emit only these colors, and depending on whether you want to accelerate the vegetative growth or to produce flowers or fruits, you can use respectively only blue or only red light.

  • Violet- violet light has a limited effect on plant growth, but it can help your plants when it is combined with red and blue light. Adding violet light enhances the color, taste and smell of plants.
  • Blue- Blue light is important for photosynthesis. This part of the spectrum has a leading role in the vegetative growth of the plants and roots development. It is good for baby plants, and even the seedling stage.
  • Green- Green light typically penetrates deeper into a leaf than blue or red light. It is important to be said that pigments other than the chlorophyll actually absorb 85% of the green light. Here is why it is also important for your plants health. 
  • Red- Red light boosts your plants in many ways. It aids chlorophyll production, plus stimulates the growth of stems, flowers, and the production of fruits. Here is why it is great for blooming plants like orchids.

How Long Should You Leave LED Grow Lights On?


Indoor plants require more natural light than the outdoor plants. They need approximately 14- 16 hrs of light.

Of course it is almost impossible to offer them natural light for such a long period. To get efficient results you can keep your LED grow lights on for 8-10 per day.  

It is good to remember that it is not a good idea to keep the lights on 24/7. Do not forget that your plants need their light- dark cycle in order to grow properly.

The dark period is the time when they rest from producing food and use the energy they have stored during the light period.
