6．Instruction of installation：

Example：Using in greenhouse

                       Install distance 4m±2m

（1）               Install height :   2.5m ± 1.5m

（2）               Install distance ：4m ± 2m

（3）               Supplement lighting time: 8-16hrs

Note:

1.    The suitable installation height should be 2.5m±1.5m. The lower the stronger will the photon flux density be.

Adjust the hanging height of led grow light in different growth stage according to the needs of plants.

 2. The suitable installation distance should be 4m±2m. The closer the stronger will the photon flux density be. .Adjust the distance to get enough photon flux density according to the needs of plants in different growth stage.

 3.  Indoor used only, don’t use in dripping water or dripping irrigation place to avoid light

damage

  4.  The supplement lighting time plus sunlight lighting time should be 8-16hrs.There is old saying ‘too much water drowned the miller’. No time rest and digestion-absorption,it will affect the growing speed.

  5.  You can get better result if you use the led grow light and HPS light together.

(the ratio of 90W led grow light and 600HPS light: 6:1)

6. Turn off the power supply when thundering and lighting, avoid damage to the led grow light.

7．Technology suport:

a) LED wavelength test report:

  u Wavelength of the red led unit (Peak) is 660.2nm

u Wavelength of the blue led unit (peak) is 451.7nm

b) Cycle lighting time

  1. Short day plants: flowering when the daytime is lower than the critical value of lighting time that plants need.

  2. Long day plants: flowering when the daytime is higher than the critical value of lighting time that plants need.

  3. Middle day plants: the daytime won’t affect the flowering of the plants.

c) Adjust cycle lighting time

Control flowering period,according to the different flowering period plants.use artificial short day(pull black cloth)or artificial long day(increase lighting time)

1. Aritificial short daytime

• Pull black cloth

–  Opaque material blocks all light

–  SDP induced to flower

–  Reflective to reduce heat delay

–  Can be automated

–  Can ‘double’ as thermal blanket to hold in heat on cold nights

2.  Aritificial long daytime.

• protract daytime.

–  incluce blossoming of long day plant

–  Light (FR containing) for 3-6 hrs at end of day

–  Low intensity (1-3 mmol/m2/s, 7-10 fc)

• prevent in dark period

–   prevent blossoming

–  2-4 hrs of low light during dark period

–  Want little FR in light

3 . Interaction effect of temperature

It’s influence with temperature of critical day time

•  Short day plant(SDP)，critical daytime will be shorter when tempreture increase

– Mums

– Poinsettias

• Longday plant (LDP)，critical daytime will be shorter when tempreture taking down.

– Fuchsia

d) Photomorphogenesis regulation:

The research in photomorphogenesis ,the result will be best when lighting with red and blue colour together

 The figure 4: ( ratio of red and blue led: 8:1)

                                                                                                                          Get the best result.

 Morphological and anatomical characteristics of the stem, leaf  will change evidently when the piper nigrum and perilla frutescence grow under suitable light wavelength of the LED. The speed of photosynthesis will be increased when the light density increased. The composite wavelength of the LED will increase the quantity of the stomata of the marigold and salvia officinalis plants.

e) Comparing test of the fluorescent light, metal halide lamp and led grow light

1.Speed of growth

Test of lettuce growth: lighting 12hrs per day, lighting time 80hrs. The lettuce grows best under the led grow light.

Plant is the only kind of living object that can transfer solar power into substance.

The photosynthesis of plants is the basic of every life..The wavelength range that photosynthesis needs is 400-700nm(visible light). The light not only infuence the photosynthesis but also the photoperiod adjusting and the light quality(ratio of red and blue light etc) also play an important role in the growth of shape.

The special wavelength of red 660nm, blue 450nm of led grow light will effect flowering time, quality and flowering lasting time and also can icrease the bud and flower quantity, reduce the flower reaction, regulate the length of stem and flowering period. The flowering time and growth speed can be controled by the LED grow light so you can put them on market in good time.

2.    Light quality and ingredients of the plant

Vegetables and fruits which grow up under LED grow lighting are fresh, sweet and provide more nutrition.

	Fluorescence lamp	metal halide lamp	LED grow light
Weigh of up ground parts (g)	8.2	9.3	13.8
Fibre(%)	1.8	2.8	3.9
vitaminC(mg/100g)	54	56	78

According to the reseach, the mixed wavelength of the led grow lighting can improve growth of spinach,carrots and lettuce,develop the shape index, maximum sugar beet accumulation, produe most sugar and starch in the hair root.

3、Lack of lighting

Lack of lighting consequences that photosythesis can not run ordinary.plants can not accumulate nutrition which will lead to :

n  In nutrition growing step,nuturition can not be accumulated and in a weak growing ,effect the bloom and fruits.

n  In blooming time, it will lead to falling down of flower and fruits.

n  In the process of fruits growing and flavor developing, photosythesis was handicapted which will lead to disshape,bad ,samll shape as well as lack of muturition,low vc,bad flavor.

n  Weak lighting delays the growing,which lead to miss good time of marketing.
