Light is an essential part of the plant living cycle. Without any light, source plants cannot live their life. In fact, light is required for every living organism on the planet. We humans also need light to live a disease-free life. Sunlight is the only best source of vitamin D. An average human being should get 1 hour of light each day, recommended by doctors.
Plants also need light to grow healthy and produce food for humans. The nutrients and intensity of light that the Sun offers cannot be duplicated at this time or in near future. Plants absorb light through their leaves. They use this light energy to produce their food this process is called photosynthesis.
This is the reason in winters we have few options to grow in our garden.
In this post, you will learn about the strong connection between plants and sunlight or artificial light.
How does light affect the plants?
Light directly affects the plant’s health, its production power, and diseases resistance power. Plants that do not get proper light develop weak and do not produce yield. For photosynthesis plants need light, carbon dioxide, and water. With these 3 things they make their food and release fresh oxygen in the air for us to breathe. This cycle continuous in all parts of the world where plants are present.
The function of Light:
To make food plants need light. They absorb carbon dioxide from the environment and water from though their roots. It does not matter you use full spectrum Best LED Grow lights or sunlight to grow plants. They just need a full spectrum of light to grow and to produce food.
In the case of grow lights use a Plant light meter to measure the amount of light your plants receiving from the light.
After making their food they release the by-product in the atmosphere that is oxygen. The green pigment gives color to the plant leaves. Absorb most of the light and transfer it to the different parts of the plant.
Type of light and plant light meter
There are two types of light that plants need to grow. One is our natural source of the light hat is Sun. The second is artificial man-made grow lights that produce the same spectrum of light as the sun. A plant light meter is used to measure both types of lights. It tells you about the light absorption rate of a plant. So that you can increase or decrease it according to the size of the plant.
In the initial growth, stage plants need a high amount of light because the product leaves, grow big in size. Once they grow to their full size then they absorb light and use food to make fruits for us. In the vegetative stage and fruiting stage, they need a high amount of light energy.
In the flowering stage, the red and yellow light spectrum plays the most important role. This is the reason many professional growers change their grow light in the flowering stage. They shift to the HPS lights for better flowers.
The good news is a light meter can measure all types of light. Always use a digital light meter for ease of use. Digital plant light meter gives you the readings in numbers. It is also easy to read it on an LCD screen.
If you want to grow a plant outside in the open air. It can get light from the Sun but in indoor gardening, you need to use grow lights. To know how much light is your plants absorbing you should buy a Digital plant Light meter.
