Blue Light Spectrum (400–500 nm)

Blue photons drive the photosynthetic reaction, although from an energy standpoint, one might consider them less efficient than green or red photons because their high energy isn’t fully utilized; some of the energy is essentially lost compared to photosynthetic photons with a longer (less energetic) wavelength. However, at least a minimal intensity of blue light is needed in sole-source (indoor) lighting applications for normal plant growth. In addition, blue light regulates the opening of stomata, which are the tiny openings on leaves that control both water loss and the uptake of carbon dioxide. Generally, only a low intensity of blue is needed in a light spectrum for fully functional photosynthesis.

Horticulture lighting primarily focuses on red and blue wavelengths. These are the two most important colors on the visible light spectrum for promoting plant growth. That is why products on the horticulture lighting market often give off a purple glow—it is from the combination of red and blue light. Every color within the light spectrum does have an effect on plant growth. After all, in a natural outdoor setting, plants are exposed to sunlight, which contains the full spectrum of colors. So how does each color wavelength affect plants? blue: this is the most important light for plant growth. It is easy for chlorophyll to absorb and convert into energy.

When growing under led s was in its infancy, many scientists believed that only red and blue light affected photosynthesis. The idea was that chlorophyll was made of green pigments and thus have peak light absorption in the red and blue wavelengths. Therefore, for optimal results, this narrow spectrum would be the best. However, if you look at the plant as a whole rather than just the top leaves, plants do not always do well with such a narrow spectrum. These setups also tend to flood the canopy of a crop while neglecting the lower leaves of a plant. This leads to some plants’ lower leaves dying as they cannot reach the photons at the top of the canopy.

As we have already mentioned in part one of this blog series: plants use different parts of the light spectrum for doing different jobs, and their exact requirements change somewhat as plants go through their different growth stages. It is accepted wisdom that blue in the spectrum is good for vegetative growth and helps keep internodes short, while red in the spectrum is great for powering the flowering/fruiting stages. It is worth mentioning that far red in the spectrum triggers something called "shade avoidance", causing lengthening internodes and petioles (leaf stalks) in the vegetative stage and it is not regarded as a good thing during that time.

Green Light Spectrum (500–600 nm)

Key benefits 1. Reduce the cycle time of plant 2. Reduces energy costs with high-efficiency led lighting, 60% less electricity consumption compared to conventional lighting 3. Eliminates the need for ballasts and reflectors and the cooling system. 4. Installs easily and safely. 5. Improves results for vegetables, flowers and more in large and small environments. 6. Best suited for fruit and flowering crop also support faster growth for leafy crop and microgreens. 7. For best result keep light to light distance 6-8 inch and light to plant distance 10-14 inch.

What we perceive as white light from the sun is actually made up of all the colors of the rainbow. The three major colors of light are red, blue, and green. We can tell that plants don’t absorb much green light because it reflects off of them and into our eyes, making them appear green. The fact that leaves don’t usually appear blue or red means that they absorb those parts of the light spectrum and use them to grow. The effect of blue light on plants is directly related to chlorophyll production. Plants that receive plenty of blue light will have strong, healthy stems and leaves.

Ever wonder how we keep our plants so healthy in a low-light space? grow lights! grow lights! grow lights! not only are mother. Life plantspectrum lights gorgeous and minimalist, they're also the best grow lights we've used yet! you won't be disappointed. If you want to check these out in person come by and visit our shop. Grow light for the professional home grower. Compact. Effective. Extremely modular. Ps16 was designed to keep smaller houseplants healthy with a full-spectrum, sunlight mimicking grow light. Perfect to maintain and grow your cacti, succulents, cuttings, tropical plants, herbs, microgreens, or even terarria.

Grow light led with balanced light spectrum for seeds and greens is designed to fit your plant's growth stage. Grow light uses a balanced spectrum with a red: blue ratio inspired by best practices of professional growers. The balanced spectrum allows not only chlorophyll but also other plant pigments to optimize their light harvesting. Compared to typical purple grow lights, the light features high ppf or photosynthetic photon flux to provide more light for photosynthesis and growth. The white light appears more natural to the human eye, so you can appreciate your plant's beauty and spot pests or discolorations to help keep your plants healthy.

Red Light Spectrum (600–700 nm)

Our eco gardens full spectrum grow lights  have 360-degree flexible gooseneck made from quality tubing to keep it to a fixed position. It has a metal clamp that allows the lamp to be placed anywhere in your home or office. The lights have a timer setting that automatically turns off the light in 3, 9, and 12 hours. Enabling you to provide the proper light spectrum to your plants even you are not around. This light emits blue and red lights. The blue light affects the formation of chlorophyll, for the plants’ strong growth and healthy stems and leaves.

With a robust metal design, and quality light emitting diodes (leds) which emit a "full spectrum" of wavelengths, this product is a quality investment for anyone hoping to level up their plant game! the primary wavelengths of light required for plant growth are the blue and red wavelengths. These segments of the light spectrum are crucial in aiding a plant's growth as blue light stimulates the formation of chlorophyll (crucial in the process of plant photosynthesis which aids healthy leaf and stem growth), and red light promotes germination, root growth, and bulb development. This product provides those wavelengths, as well as others to result in a user friendly "white light" output.

How to use Grow Lights for Seedlings

Depending on what kind of plants you grow, you can choose the best lights for the supragarden® system. Led lamps can be connected in series, up to 8 lamps together and easily hung on the underside of the plantsteps. Daylight led with cool light (6500 kelvin): especially suitable for plant seedlings and edible green plants such as salads and herbs. Contains two shades of white as well as two red and blue led types. Blue light is especially suitable for the vegetative growth phase and it supports the growth of plant leaves and stems. The added red light helps the plant to flower.

Our top pick is the GE BR30 Grow LED Light Bulb

The bottom line is that led grow lights are no more dangerous than any other type of grow light. Hps is much more dangerous than leds – high heat and risk of burns, risk of broken bulbs and fires, high environmental damage due to mercury content, high carbon footprint.
