Grow lights are a category of indoor lighting for plants that allow you to grow the most succulents, herbs and houseplants during any time of year. This artificial light source is a compact way to stimulate plant growth, at all growth stages, by emitting blue light (which helps the plant grow) and red light (which helps with seed germination and blossom development). These lights range from professional grow lights for large commercial operations to small lamps for hobbyists and indoor herb gardens.

Every child knows that plants grow and thrive when they are watered, soiled and receive light. However, serious growers and gardeners know how to tailor the soil, lighting conditions and watering system to their plants’ needs. For instance, sunlight naturally contains a broad range of light wavelengths, many of which are lacking in your typical LED or incandescent bulbs. Likewise, plants respond to the natural rhythms of sunset and sunrise, and the best indoor grow lights include timers to mimic this natural cycle. While outdoor plants naturally receive all the spectrum lighting they need, indoor plants tend to lack proper lighting. This is where a grow light comes in handy.

Why Choose Full Spectrum LED Grow Lights?

Different LED Grow lights emit different wavelengths depending upon their spectrum pattern. These different light wavelengths stimulate different stages of plant growth, and thus while choosing the correct grow light, you must check its spectrum according to the sort of stimulation you want. For example, LED that is perfect for vegetation might not be as effective with flower development.

But Full Spectrum LED Grow Light caters for the plant stimulation at different stages according to your need, and thus you can use it for all. Full-spectrum grows light is an adjustable LED light that emits lights of different wavelengths similar to the Sun. In other words, Full Spectrum Light emits all wavelengths of light that are emitted from the sun.

Many plants not only require red or blue light but all the colours of visible light (even in a limited amount) for proper growth. For such plants, Full-Spectrum light is the best suitable option. For example, the plant requires different lights of different wavelengths at its various growth stages, and thus it is advisable to use full-spectrum light for its healthy growth.

How Lighting is Measured

Before going through the various types of artificial light, it is good to see how light is measured, and what each bulb has to offer.

There are a few ways that light is measured, but some are almost obsolete, but still used in some things. Foot-candles or candle power is one such term, and this often relates to flashlights or spotlights that shine in millions or thousands of candle power.

Temperature is one of the primary terms you will see when growing in hydroponics and when looking for the ideal light. This temperature has nothing to do with heat output, but it is a reference to the natural color of the light produced.

When we see cool lights, these deliver light at the blue end of the spectrum (also called blue light) while when we look at lights that are warmly looking, these are providing light at the orange/ red end of the spectrum.

Lights can be measured by watt power, nanometers (nm), or Lumens most often. The watt power (or wattage) is the unit of energy required to run the lighting, and it is the term most people are familiar with. When it comes to growing lights, these are often rated to the number of watts needed for each centimetre squared of the surface to be illuminated.

Lumens is a reflection of how bright an LED grow light is, and although used, these lumens are not actually a rating that does anything for the plants. The light required by plants is beyond the physically visible spectrum.

When light is measured in nanometers, this is actually the light we can see. This visible light falls in the range of 400 to 700 nm. When you compare this to the colour spectrum, the warm or red end will be reading 730 nm, and at the other end in the colour part of the spectrum (violet), this will be reading 400 nm.

Almost all indoor grow lights fall in the range of 450 nm to 730 nm. These are the most crucial nm measures with one addition of 650 nm in the middle of the spectrum.

We all know that plants need to photosynthesize, and for plants to do this, there is the need for light at the 450 nm and 650 nm levels. With these, plants can create the food it requires from the light available along with water and carbon dioxide. It is the green pigment where chlorophyll is produced.

When plants use the 650 nm and 730 nm ranges, this allows them to control their flowering through another pigment which is called phytochrome.

This is why the full spectrum of light is required at varying stages of a plant’s growth, and this is why it is crucial to have the best grow lights that allow growers to replicate this.

Conclusion

Grow LED lights can be highly beneficial for your indoor growth if you buy the right one after examining the various aspects. We hope that our detailed buying guide on LED Grow lights will help you choose the best LED grow light for commercial spaces and small rooms. Happy gardening!
