Year-around Gardening with SANSI LED Grow Light for Indoor Plants



When referring to winter, all living things seem to be asleep as well as plants. As for grow plants lovers, it is an indispensable part to let our plants enjoy full spectrum in the growth part. SANSI led grow light full spectrum can solve problems and make the whole year-round gardening.

What is in the sunlight?

The sun is composed of infrared light, visible light and ultraviolet light. The sunlight is multifunctional in terms of plant photosynthesis, heating as well as sterilization.

Physiological effects of light quality on plants:

Light compositionWavelengthsFunction
Ultraviolet light315-400nmChlorophyll absorption is minimal, affecting photo-period effect and preventing stem elongation.
Blue-violet light400-520nmThe blue light part of chlorophyll has the highest absorption rate of carotenoids and the greatest impact on photosynthesis.
Green yellow light520-610nmThe absorption rate of pigment is not high.
Red orange light610-720nmThe peak value of this band is best at 660NM, and the absorption of chlorophyll is low, which has a significant effect on photosynthesis and photoperiod effect.
Infrared light720-1000nmLow absorption rate, stimulates cell elongation, affects flowering and seed teething.

Red Light

Red light inhibits internode elongation, promotes lateral branching and lobulation, delays flower differentiation, and increases chlorophyll and carotenoids. It can inhibit the photosynthetic product output from the leaves and increase the starch content of the leaves and promote the growth of seedlings.

Far infrared light

Far infrared light (FR) can counteract the red light effect in many cases. A low R/FR ratio results in a decrease in photosynthetic capacity of kidney beans. In the growth chamber, the far-red radiation is supplemented with an LED light source to reduce the anthocyanin, carotenoid and chlorophyll content, and the fresh weight, dry weight, stem length, leaf length and leaf width of the plant are increased. The effect of supplemental FR on growth may be due to an increase in leaf area resulting in an increase in light absorption.

Blue light

Blue light can reduce internode distance, reduce leaf area, reduce relative growth rate, and increase nitrogen/carbon (N/C) ratio. High plant chlorophyll synthesis and chloroplast formation and positive chloroplasts with high chlorophyll a/b ratio and low carotenoid levels require blue light. Under the red light, the photosynthesis rate of the algae cells gradually decreased, and the photosynthetic rate rapidly recovered after going to blue light or adding some blue light under continuous red light.

For photosynthesis and growth of plants, only red light is not enough. Wheat can complete its life cycle under a single red light source, but in order to obtain tall plants and large numbers of seeds, an appropriate amount of blue light must be added. Excessive blue light inhibits plant growth, shortened internodes, reduced branching and leaf area. Plants have significant species differences in the need for blue light.

Indoor Plants Demands

Long-day plants— flowering time is more than 12-14h per day to form flower buds; and the longer the illumination time, the earlier the flowering, otherwise the plants can only grow vegetatively such as Radish, spinach, wheat, balsam.

Short-day plants—plants that have less than 12 hours of light per day, but require more than 8 hours to flower a firm plant. Moreover, within a certain range, the longer the plant receives darkness, the earlier the flowering, and only the vegetative growth without flowering under long daylight such as corn, sorghum, rice, cotton.

Sunshine neutral plant—it blooms under different lengths of sunshine as long as other conditions are suitable after vegetative growth for a period of time.

Medium and sunshine plants—plants are close to the same length and can bloom in day and night such as dandelion, green beans, cucumber and tomato.

What if plants don't get enough light?

If light's do not get enough light they will not produce enough chlorophyll. It will happen to be chlorosis. Chlorosis is incredibly dangerous to a plant and its initial signs are yellow leaves due to a lack of iron within the plant. So if you think your plant is getting yellow, please be aware of that situation.

LED Grow Light

LED has the ability to control plants growth. Although the sun contains the entire spectrum, LED plant lights can be used to adjust the spectrum required by plants to meet the needs of different plant photoreceptor. Traditional light source requires a 0.5 kW per square meter,LED only needs 0.27 kW. This will reduce power consumption by about half. So efficiency is the biggest highlight. The application of the new LED light source can restore the original appearance of plant growth. Now, the taste of cucumbers and tomatoes are also good, and there are reasons why the light is not standardized.

Full Spectrum

The visible light whose spectral composition is close to sunlight is suitable for the whole life cycle of plant growth, especially for plants in the seedling stage. Each Sansi LED chip has an evenly distributed spectrum between 400-780nm. Full Spectrum can meet needs of various kinds of indoor plants. Make plants enjoy the lighting of each time period.

Instead of having multiple LED chips with individual colors (white, blue, red, far red), each LED chip has a mix of each color giving off a whitish glow. Compared with other grow lights (all competitors use aluminum LEDs), ceramic dissipates heat more efficiently than aluminum because it is non-conducive. This allows our LED chips to be mounted directly to ceramic; making each chip free of fans, housing, adhesive, and PC boards. Ceramic modules have fewer parts than conventional LEDs, and therefore conduct less heat and generate more savings.

Growth Spectrum

Mainly composed of red and blue light spectrum, trace yellow-green light. The red-blue ratio is close to 3:1, which is suitable for the growth period of plants. Because the growth period of the plant in the whole life cycle is 60-70%, the spectrum is the most cost-effective from the perspective of pure economy.

Maturity Spectrum

The red-blue ratio is about 5:1, and the red light spectrum is more, which is suitable for the flowering result period of plants. It is beneficial to control the flowering cycle and the accumulation of organic matter in plants, and is commonly applied to the maturity of melons and fruits.

Because the spectral components do not contain deep infrared light (IR) with a wavelength >1000nm, the light on the plant light is less than the heat radiated onto the plants. When the plants are irradiated at close range, there is no risk of "burning" the plants. Making your indoor plants a healthy living environment!
