Simple Guide To Indoor Grow Light Spectrum

Simple Indoor Grow Light Spectrum Guide

Simple Indoor Grow Light Spectrum Guide. One of the three fundamentals of plant lighting is selecting the appropriate light spectrum. Actually, sunlight and other types of light that we see are composed of a variety of colors. For the best plant growth in indoor gardens, it’s crucial to provide the right spectrum at the right time.

We’ll keep things straightforward because I’m a big fan of hydroponic gardening made simple.

There Is A Light Spectrum For Pigments

In order to complete the process of photosynthesis, plants use light energy. Plants have pigments, which are molecules that selectively absorb some wavelengths of light while reflecting all others. The color you see is a reflection of that light.

The process of photosynthesis involves a number of pigments. Plants use carotenoids, chlorophyll (a), and chlorophyll (b) as their primary pigments during photosynthesis.

The Best LED Grow Light Selection

There are many reasons why LEDs are regarded as efficient. One of these is that they can be tailored to only include the colors that plants actually require while excluding the ones that they don’t. When compared to HPS lighting, LED grow lights produce less heat, making their impact on electricity costs almost imperceptible. For hobby hydroponics, LED grow lights have emerged as the best option overall.

Most LED grow lights are full-spectrum, allowing you to use them as your plant enters the flowering and fruiting stages under the same conditions. Some lights have switches that, when activated, add various light spectrums, while others continuously emit all of them. Your LED lighting should include some of the following for the best all-around growth in all phases of a plant’s life cycle:

A red LED (600–700 nm)

RGB LEDs (400-500 nm)

Far-reaching LEDs (700–800 nm)

certain white LEDs

Other types of LED lights include:

certain green LEDs (500-600 nm)

a few IR and UV LEDs

The combination of these hues is what gives many LED grow lights their purple appearance. Growing in popularity are LED grow lights that contain a higher percentage of green, which gives the light a brighter white appearance. With the help of this white light, you can examine your plants more easily and take better pictures of your garden.

Below are my Viparspectra grow light and my MarsHydro grow light, both of which emit a visible white light and a visible purple light, respectively.

Color temperature of fluorescent and HID grow lights

LED grow lights operate somewhat differently than fluorescent and HID (high-pressure sodium and metal halide) grow lights. The single colors that LED lights emit are not produced by these “traditional” grow lights. We typically see either bright daylight or a soft yellowish hue when looking at the light emitted by one of these grow lights.

The “Kelvin” unit of measurement for these grow lights is based on color. The Kelvin scale can be seen below.

Blue light at the higher Kelvin end of the spectrum is necessary for plants in the vegetative stage. Vegetative growth responds well to the same lighting conditions that are ideal for seedlings and clones. Use bulbs that are between 5,000 and 7,500 Kelvin for vegetative growth.

Your plant will require more of the red spectrum of light at the lower end of the kelvin scale as it moves into the flowering and fruiting stages of its life cycle. Low-energy light encourages fruiting, blooming, and flowering. For plants in the flowering or fruiting vegetative stages, you should use more bulbs that are in the 2,000–3,000 Kelvin range. High-pressure sodium bulbs should be used instead of HID lighting since they produce more red light.

Conclusion

It’s crucial to select the proper light spectrum and color temperature for your plants. Depending on the type of light you’re using and the stage of growth your plants are in, you might need to change lights as they transition into flowering. I hope this guide assists you in choosing which bulbs to use after you’ve chosen a light source.
