Best Full-spectrum LED Grow lights

In the LED market, there are many indoor grow lights to choose from, so when you buy Full-spectrum grow lights, figure out which grow lights are suitable for your plants.

When buying LED grow lights, not all LEDs are manufactured the same way. If you want to understand that Plant growth light can provide the true power of the entire lamp, you need to pay attention to the quality and quantity of light generated by the lamp.

This article will help you understand "spectrum" and "PAR" and other ways, their relationship and how to use them to determine how to choose the best Full-spectrum grow lights at the best price for your garden.

What is full-spectrum?

LED grow light technology no longer uses specific frequency bands, but the entire industry is committed to providing the widest possible spectrum. You can see this if you notice that most well-known LED companies are moving away from pink/violet lighting and replacing their LEDs with "white" chips.

These white chips are produced by a phosphor coating method, where the coating is deposited on the LED die. The exact shade or color temperature of the white light produced depends on the dominant wavelength of the blue LED and the composition of the phosphor. The thickness of the phosphor coating will cause the color temperature of the diode to change.

The ideal growth light will be the light that can replicate the solar spectrum while allowing us to adjust the light intensity according to actual needs. This will be the pinnacle of the "full-spectrum".

For our intent and purpose, the radiation spectrum of the sun spreads very uniformly and reaches a peak at a wavelength near the PAR spectrum.

What should the ideal spectrum be? How many colors do plants need?

In order to absorb light, plants use some primitive but efficient eyes in our eyes, which we call pigments. The most abundant plant pigment is chlorophyll, which is most effectively used to capture red and blue light. In addition, there are many other pigments, including carotene and lutein, which can absorb other wavelengths of light and transmit it to the photosynthesis process.

It should be noted that green light actually penetrates deeper into the leaf than red light and can drive photosynthesis more effectively. This is because the top layer of the chloroplast containing chlorophyll becomes saturated, and the green and yellow can penetrate deeper into the leaf tissue and reflect to the surroundings until they are absorbed by another chloroplast containing chlorophyll or auxiliary pigments.

Understanding PAR readings

First, it is necessary to measure PAR or photosynthetically active radiation. PAR can basically measure the luminescence in the photosynthesis range of 400-700nm. This represents the area of ​​light that the plant uses for photosynthesis or growth. PAR is measured by the amount of micromole light per square meter per second. Although PAR is a key indicator, it can only illustrate part of the story. There are many areas within the PAR range, and plants only absorb a small amount in the green area (560 nm). Therefore, the reading of the spectrum must be combined with the PAR reading to determine how much these micromole molecules are generated from which bandwidth. Spectral readings are obtained by using a device called a spectrometer. Together, these two readings can fully illustrate the effectiveness of the lighting. PAR shows the intensity, and the spectrum shows that the intensity is proportional to the actual wavelength of the plant, not just a waste of energy. The readings produced by these two measurement tools not only show the emitted wavelength or color, but also the absorption value of that particular wavelength. By looking at this graph, you can determine whether the light emits a wavelength suitable for plant photosynthesis, and whether the radiation absorption peak it emits is suitable for robust and high-quality Plant growth light.

Main factors to consider

Now that you understand the scientific principles of full-spectrum LEDs, you need to consider these most important factors when deciding which LED to buy.

cost

Currently, Full-spectrum LED grow lights are expensive. The cost of building a system that relies on these indicators may be higher than the cost of standard HPS or HID settings. However, since LEDs are more efficient than HID lighting, you will save a lot of money in the long run. For example, the average life span of HPS bulbs is about 10,000 hours. Compared to this, LEDs have a lifespan of 50,000 hours, and you will see cost savings over time.

volume

Most HID or CFL lighting setups are bulky. This is not necessarily a bad thing, but if you try to grow in a smaller space, it may become difficult. The full spectrum lamp is relatively small and does not require a ballast or reflector, thus freeing up space in the growth tent or growth chamber.

heat

Light and heat are forever entangled. The temperature of the growth chamber is a key variable, and the growth lamp is one of the biggest factors causing the temperature rise. This is why ventilation in the planting room is so important.

Full-spectrum LED lights actually do not have this problem. In fact, due to the low heat output of such lighting equipment, in fact, some growers have to manually heat the room in the colder months. This means that if you grow in a warm climate, you don't have to worry about overheating the growing space.

Compare Full-spectrum LED grow lights

The following different types of LED grow lights lighting technologies are still very valuable for quick comparison and comparison.

When comparing LED grow lights with HID grow lights, you are actually comparing with three different types of lights: high pressure sodium (HPS) grow lights, metal halide (MH) grow lights and ceramic metal halide (CMH) ) Grow lights.

Full-spectrum LED grow lights and high pressure sodium grow light

Generally, HPS will eliminate the full spectrum setting in terms of cost, but will lose heat output and the ability to grow throughout the life of the plant.

Full-spectrum LED grow lights and metal halide grow lights

Generally, MH is suitable for plant growth, which has a low cost, but emits a lot of heat and is not suitable for the entire life cycle of plants. However, if you only grow nutritious plants, the effect is good.

Full-spectrum LED grow lights and ceramic metal halide grow lights

Compared with Full-spectrum LED grow lights, CMH lights are the best HID competitors. They sent a good spectrum, the cost of the same full spectrum lighting.

Full-spectrum LED grow lights and compact fluorescent lights

Although energy-saving lamps are effective, they are best used in the vegetative growth stage of plants. This is because they usually can not issue sufficiently high light intensity in the right spectrum, the plants can not perform well in the flowering stage.
