Are grow lights better than sunlight?
Generally, sunlight is best for plant growth, because artificial grow light cannot replicate the light (wavelength) of a specific color that is most suitable for plants growth. However, artificial grow light can be a good complement to sunlight, especially in winter or places without sufficient sunshine.
Plants need light to grow and thrive. Without light, they cannot produce enough energy. Sunlight is composed of many colors, including blue, green and red. These colors are important to plants because they help regulate their growth. Sunlight also contains ultraviolet (UV), which is good for plants because it helps them produce vitamin D. Sunlight produces a full spectrum of light, including blue and red light that plants use to grow and generate energy. Plant lamps are as good as sunlight and have greater flexibility.
Advantages of sunlight
One of the best functions that sunlight must provide is that it emits a wide range of wavelengths. When the light passes through, the rainbow color on the crystal and the ground naturally exists in the sunlight. Since plants need one or both of the red or blue wavelengths, sunlight can provide all your plants with the required wavelengths at the same time.
The sun moves in the sky in the same way every day, so you can adjust your plants outdoors or in windows as needed to provide them with perfect light.
Another advantage of sunshine is that it costs nothing to use. As long as the sun exists in the sky, it can provide free light for your plants to survive. No other light source can compare. For these reasons, most gardeners first want to make the most of the sun.
Disadvantages of sunshine
Although sunlight can provide all the benefits, there are some disadvantages to relying on it alone. The main one is that sunlight is not always available, depending on where you live. For colder climates, the days become shorter and the light intensity decreases, resulting in limited light and reduced temperature. This makes it impossible to plant some plants outdoors and requires different light sources to help indoor plants thrive.
Grow lights or LEDs are designed to simulate sunlight by emitting full spectrum grow light to help plants photosynthesis. Although the sunlight is free, its movement and position changes in a day, week and year pose some challenges to plants. Sometimes the weather is too hot or too cold to grow any plants. On the other hand, a plant grow lamp or LED grow lights can provide constant illumination for a long time. You can customize the artificial plant grow lamp to produce the specific light required by the plant, so as to fully control the growth of the plant in your hands
Artificial grow light has a major advantage over the sun because you can always use it without worrying about seasonal or weather changes. You can place artificial grow lighting system wherever there is space for it and the plants you care for.
You can also have better control over how much light your plants receive and the type of grow light you use. There are several grow light bulbs to choose from, depending on the type of plant you grow. Fluorescent lamps, whether tubes or bulbs, are popular because they can last for a while and stay cool, so you don’t have to worry about overheating plants. LED grow lamps are energy-saving, have the longest service life among all bulbs, and feel cool, so they are also a good choice.
Although artificial grow light has different options, they do not all provide the same broad spectrum as sunlight. Fluorescent lamps and LED lamps usually only emit blue light, while incandescent bulbs produce red wavelengths. Therefore, selecting the wrong grow lamp will affect the growth of plants. Both halogen and garden grow light bulbs are available, but the price of the grow light bulb may not be within your budget. Similarly, the cost of artificial grow light is also high, because you need to buy bulbs and pay operating costs, which may increase your monthly energy costs, especially for plants that need high light conditions.
There are some main differences between sunlight and grow light:
1-Cost: sunlight is free, and plant growth lights can be expensive.
2-Resources: sunlight is the natural light from the sun, while grow light is an artificial light specially designed to imitate the sunlight.
3-Color: sunlight consists of many colors, including blue, green and red. Plant growth lamps usually have only one color (usually red or blue).
4-Controllability: sunlight is uncontrollable because cloud patterns may hide it. You can control plant grow lights to select when and when plants are exposed to them.
5-Location: sunlight is more suitable for outdoor plants. Grow light is more suitable for indoor plants.
6-Climate: sunlight is not applicable to all places and climates, and growth light can be used even in areas without natural sunlight.
In the final analysis, as long as you prove to the plant that there is enough light, any kind of light source can. Any one is a good choice, so make the best method for you and your plants.
