LED grow lights are completely different from conventional LEDs. It is dedicated strictly projection spectrum wavelengths for plant photosynthesis and lamp spectrum wavelengths are in the range of 380- 750nm. The brightness of the LED grow light emits, the plant completely absorbed. However, to use the light to bring the highest efficiency for plants and promote the value of artificial sun for plants, the following questions will help you.
1. What type of led grow light should you buy?
All products of LED grow lights can be used to grow vegetables, however, based on the functions and characteristics of the plant, there are some sorts of specialized lamps for plants and for vegetables.
First: Methods of growing vegetables will decide how to use suitable a led light. It is a good select if you use the best led grow light 2017 because it has many functions.
Second: Vegetables are different from other common plants, vegetables need to grow over time for us to harvest and how to grow vegetables as fast as possible. Therefore, vegetable lights should be of sufficient spectrum for all stages of growth and development.
2. If your house has some plants completely without sunlight, what type of led grow light and how to use correctly?
With bonsai in the home, we need to split into two clear concepts to determine the purpose of lighting and how to use accordingly.
First: Using a lamp to sustain life for indoor plants, we only need a fixed two-wavelength (typically 460nm Green and 660nm Green). And the green and red ratios will depend on the groups of plants that have the combination of green and red to suit that group, and the additional lighting time for the plants from 10-12h per day is guaranteed.
Second: Second: Using lights to stimulate the growth of trees, we should use lamps with many wavelength spectra (typically 620nm Green and 730nm Green). Besides, it is important to rely on the optical characteristics of the tree as a long or short day that determines the time to stimulate flowering as well as stimulate the growth of plants.
3. If you want to buy LED grow lights to add light to the tree, how should light?
In this case, there are two following ways:
Method 1: We will turn on the light from 4h and turn off the lights at 11h and then the tree will have sunlight to 14h which means that the tree has a continuous time series from 4h to 14h. Therefore, from 14h to 4 am (the next day) the tree will understand that it is night time.
Method 2: We turn on the lights from 14h to 21h then turn off the lights so plants will have time series of continuous days from 11h to 21h and from 21h to 11h (the next day) is night time.
Both of these projections are intended to give the plant a fixed day and night cycle that avoids the case that we turn the lights on incorrectly, which inadvertently creates a cut-off state that will change the biological clock. Please keep this in mind.
4. Does the LED light have a white light? Or all kinds of lights purple or pink (Green and Red)?
LED grow lights have two strips of blue and red. And the LEDs completely can produce white light (a kind of sunlight simulation). However, white light also emits red light wavelength bands for the photosynthetic as mentioned above. Therefore, it can be said that LED grows lights can be used to produce white light and can be used for plants. But in terms of economic efficiency, it will not be high because it consumes electricity for unnecessary wavelengths of light. Therefore, it is very useful for plants while also optimizing the power consumption that the light emits.
I hope that the above information and answers will help you. Good luck.
