Grow light vs sunlight
Table of Contents
The biggest challenge of indoor planting is to provide suitable light, because water, carbon dioxide, and light are necessary conditions for photosynthesis of plants. Without enough light, your plants will not be able to produce the nutrients needed for growth.
Although the current plant growth lamps do a good job of maintaining plant life, are they still better than sunlight?

Grow light vs sunlight :light quality
Sunlight can nourish the growth of everything because it can provide full-spectrum light. Plants mainly use red and blue light. (On the impact of light on plant growth, there is a related study at the University of Minnesota: Lighting for indoor plants and starting seeds). Plants mainly use blue light to grow leaves and red light to flower. The current LED grow lights are spectrally capable of emitting full-spectrum light. In some cases (if you don’t have a suitable outdoor space), the effect of the grow lights will be better.
Grow light vs sunlight:light intensity
The light intensity of the growth lamp is not as good as outdoor sunlight. 6 hours exposure to sunlight is equivalent to 12-14 hours exposure under the growth lamp. Moreover, the sunlight is free, and the growth lamp needs to pay a large amount of electricity. Of course , This is determined by the power of the device. Plants that need less light, such as plants that like to grow naturally in the shade or diffuse sunlight, only need to be exposed to a growing light for 6 hours a day.
Grow light vs sunlight:Temperature regulation problem
Sunlight will increase the temperature, which is beneficial to heat-loving plants. However, plants that like to grow in colder conditions will be affected. Studies have shown that most plants can thrive at around 70 degrees Fahrenheit. Growers who use grow lights are generally equipped with a temperature control system that can control the growth environment of plants. If your plants have strict temperature requirements, grow lights are a better choice.

If used properly, they can make plants grow well. Sunlight is a gift from nature. It is free and efficient. Growing lights allow us to grow plants indoors. This is the convenience brought to us by technological development.
