It is me below according to individual experience, and a few professional knowledge are summed up and come, if have doubt,welcome doubt. Bright and beautiful goods presses down a building (the material that thanks Brismason) :
-------------------------------------------------------------------------------------------------
Temperature
1, appropriate temperature (individual experience) : ℃ of 10 ℃ ~35.
2, grow optimal temperature (individual experience) : ℃ of 20 ℃ ~25.
Illumination
Introduce next plant chlorophyll above all:
1, structure and illumination wavelengh (the picture comes from Baidu 100 divisions) :
As above graph, there is link of Lin of a Bu in every chlorophyll, namely above the old planar structure of Mg center, have on two direction draw energy differently, corresponding is plant chlorophyll Qx, Qy absorbs a peak twice. Different to plant sort, chlorophyll sort is different, draw peak position endless also and identical. But generally speaking, the La Ziguang of the 430nm ~ 450 Nm of Qx correspondence, of Qy correspondence is the glow that 680 Nm controls. So the majority of Bu Guangdeng of completely spectral LED on market is made with wavelengh of 450nm, 650nm. Use 650nm the reason that is not 680nm is, the glow material price of 680nm is too high, although absorb 650nm of efficiency prep above, but compare to the omnibus price of plant breed aquatics not tall. (the Bu Guangdeng that I had bought 680nm, expensive still do not say, the effect also difference of it doesn't matter)
1, illumination intensity
For completely spectral to great majority Bu Guangdeng (La Guang of 450nm of 3 peak value, 650nm glow, 520nm green light, color of green smooth compensation lets the lamp look is Bai Guang) ,
(everyday 8 hours) 8k Lux enough assures 12 plants not apprentice, violet department lies 12 rolls small the brim that become angry.
The intensity of illumination of 15k Lux can make sure violet department plant becomes angry,
30k above begins 12 to begin atrophy to be basked in,
Prep above 50k can be basked in very likely dead.
To sun's rays, the issue is complex. See spectrum of a piece of sun first above all (upper, picture Baidu picture is informal of search)
Part of the orange in the graph is visible light, the green light with the highest intensity in visible light (500-550nm) plant light is amalgamative without obvious use.
Attention: LUX is an unit that measures visible light intensity! So, to the light of identical intensity of illumination, contain in point-blank sunlight approach the sightless light of one times, this among them great majority is infrared ray. Infrared ray is right floral photosynthesis base useless, but have strong fuel factor. Temperature crosses tall meeting to bring about 12 not to grow at the most comfortable temperature slow.
But! To the scattering light of identical brightness, nonexistent this problem. To scattering (Rayleigh scattering) for, just become inverse ratio 4 times of scattering intensity and wavelengh. That is to say, scattering ability of infrared ray is weak, the infrared ray in scattering light is little, calorific problem is a lot of less. (knock blackboard: Open sunshade is prevented suntanning is otiose, as a result of scattering, the ultraviolet intensity of open ground agrees basically on each direction! The ultraviolet ray that remains after sunshade keep out still enough suntans. )
So, it is good that natural light does not compare Bu Guangdeng result certainly, see water fat temperature even integratedly.
2, illumination time
If be LED Bu Guangdeng, proposal everyday 8 hours, 8k~15k Lux illumination, grow rate is optimum.
If be point-blank light, the proposal lies between glass (filter shortwave ultraviolet ray) everyday 4~5 hour is most.
Scattering light is the same as LED.
Golden bittern lamp: Did not think, basically be ultraviolet ray and green light, prevent person at most, grow the effect is very poor. Had used period of time, secondhand later sold.
Illumination time is not to grow better more, the nutrition that wants time length enough to let a plant synthesize a need only is good. Short illumination, appropriate temperature can cheat floral physiology cycle, control 12 annual at growth period. Grow more quickly.
Soil, water is fat
Irrigate the view that show fully to working, my individual expresses not approve of.
What my individual uses is the billabong of Chi Yu, deer, of 90% 3-6mm that sells meal, lava, green boil, turfy configuration grain earth, simple tube of LED 8000 LUX is raised. It is daily, which shop front worked to water, half an year did not cut off the water supply, because water,also did not see where pot sodden root. Because long-term earth grew bug to rot in damp earth,be a few. Every time the Mao Xigen that earth did to injure 12 actually fully, this actually special effect plant grows. The key is, want earth to breathe freely only, how capricious OK.
Cleaned out treasure to buy a west hill birthday last year, everyday 4 hours are lying between two glass point-blank, temperature 24 Celsius, 90% grain, a week waters, 11 months, from 8cm left and right sides, go up to 13cm left and right sides, do not have apprentice.
-- -- -- -- -- -- -- -- -- -- -- -- cent secant --
There are a few breed aquatics record pictures below.
West hill hand buys the photograph of moment to cannot be found, know to clean out the color in treasure record to classify be 8cm about only. Present diameter about 13cm, basin 14cm.
