Create the best grow light

[xdrix]

My project will be to create the best grow light for growing plant the winter.
For grow a plant required two colors of light: the red( 2000; 3000k) and the blue(5000; 6000k.
This color of light is detected by the chromatic cellular and the reaction is different at each color. The blue favorised the grow and the leaf he reduct the cellular elongation and the red increase the cellular elongation and the flowering. The light and the nutrients are convert in sugar but the effect is different between the blue and the red.
It existed the light orange (color 4000k) with a neutral color of light. Its good but the light not variated during thr day and i think that she has not a natural landmark in the time.
My project is to create a light with a variation of the color during the time of the day.
For exemple: red the morning and the evening
Orange during the intermediate period.
And blue at the mid of the day.
I search to crate a natural cycle for the plant without desequilibar.
In first time i will not take the contrast of color of light between two colors.
I will try to did a bit tempo at each light circuit for on the next light after the first light and off the first light.
Or i can create a shift between the on of the second light and the off of the first for have a period of transition more natural with two lights on.

I will calculate the generale proportion of color of light for an equilibar cycle between the juvenil productif and flowering.

For the photopetiod court days and long days and neutral.

Three lights,
Tempo
Eventualy a luminosity captor!
The important for me is to have the adapted luminosity at the time of the day.

I search an idea for on the orange light between the off and the on of red light and blue light

Tempo%:12h

Total time of the program:12hours or 720minures.
Its a good repartion of the time for the grow in juvenil time?
I may have a defisciency in blue light enlightening time.
T° of the room:between 13°C 55,4°F and 19°C 66,2°F in average the winter.
Total:
240 minutes of red light 240x100/720=33,33%.
180 minutes of blue light 180x100/720= 25%.
300 minutes of orange light 300x100/720=41,67%.

For started easily i think at the "TON" block in the transitions.I will found an idea for have two lights on at same time
my equations are
            in                                                                                  out
k1. TON.TOF                                                                                       red +orange/+blue/ the start of the morning

K1 .TON.TOF                                                                                          red +orange +blue/ the end of the morning

K1.TON.TOF                                                                                            red/+orange/+blue the start of the afternoon

K1.TON                                                                                            red +orange/+ blue/ the evening

K1/                                                                                                 red/+orange/+blue/ the night

The important for me is orange.(red +blue) for have the best photosynthesis.

. =and

+= or

/=no

If i  put a block "TON" before and after the OFF of the light can i calculate many times the same bit?

I will try to put the two blocks in the same in.

I will try to add of in more later

The electric coil K1 will order the lights.

I will try to ad more variable later

I have found a video for found a inspiration for programming my differents lights
The program is in SFC

[xdrix]

I will use arduino card for programming my light system with the function delay.
The time with arduino is in milisecondes but i can modified my timebase. For example with the formule 1x1000x3600x24
It i want on light during 12h i enter formula 1x1000x3600x12.
Why i don't use wan't use timer?
But with a timer i am limited at cycle of 24h.
With arduino i can did cycle more long of 24h with more long nights for upgrade set fruits.
In wait to have all the equipement i will use the timer but it will be more funny with arduino!

I have three differents lights color on this light panel:3000, 4300 and 6000k. I think it perfect for create natural light cycle.
For have complete light spectral i will add this light www.pearl.de/a-NX6733-3505.shtml
3000k for simulated sunrise and sunset
4300k for simulated morning and afternoon
6000k for simulated mid-day.

I like this project.

I will be trying to buy these adjustable spectrum lights in the future, but will probably modify them to connect to an arduino.

I like your plan to create specific recipes for flowering, fruiting stages.

Do you have a github where you will share your arduino code?

Programming it in a state machine might be the best idea.

I don't have unfortunately found lot of time time but i will really learn arduino or rasberry!
Electronic and electricity are expensive at this moment with our inflation.

Thank you keen101 i read yours codes!
I have also fond some groups or we share our code on discord.[brwe can eaven share our solidworks creations.
I have some funnys ideas for hang the panel-light.
