When we talk about LED displays, There are many kinds of them. As far as Shenzhen is concerned, there are many LED display manufacturers.Considering this, anyone must choose the best-LED supplier to get the maximum productive outcome with the LED display they buy.

Year-around Gardening with SANSI LED Grow Light for Indoor Plants Back 2019/01/09

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 composition   Wavelengths   Function  
Ultraviolet light   315-400nm   Chlorophyll absorption is minimal, affecting photo-period effect and preventing stem elongation.  
Blue-violet light   400-520nm   The blue light part of chlorophyll has the highest absorption rate of carotenoids and the greatest impact on photosynthesis.  
Green yellow light   520-610nm   The absorption rate of pigment is not high.  
Red orange light   610-720nm   The 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 light   720-1000nm   Low 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.
