Technical question about photosynthesis

I have a technical question on led technology. I would like to know what led chip manufacturers like Samsung do to make the led work for photosynthesis.
Do they apply a filter or do they play with the color, the wavelength?
What I would like to know is if I take several strips of LEDs of different color (K) and install them side by side as in the photo, is this suitable for making seedlings?
Or do we have to have a chip really made for it?
Look my setup, its a test , and is not for weed. Its just for seedling stage.
THANKS

A pantry light bulb can trigger photosynthesis can’t it? I’m stoned so I may require assistance also.

Same chips that light your room will do photosynthesis. But if you add a little light under 450nm and over 700nm it seems you get better results. Ymmv.

Thanks but i need more information.
I will try to find by making my own test.

i use 4000K from start to finish.

and some far red and UV-A.

Yes

no

So my setup will work?
Because i need a strip of 9 feet. So i'm not able to find this.
Remember ,is not for weed, it's for flower seedling.
We currently using fluorescent cool white and warm white...that work but the plan seem to show signs of weakness.
THANKS ALL

Plants will grow under almost any light – any photon in the PAR range can be photosynthesised. But not all photons are equal in terms or energy, photosythetic absorption or photomorphogenic response.

For seedling propagation, UVA and blue light are known to increase root and leaf mass in the early stages. UV also hardens seedlings off and can counter shade avoidence where high levels of far red are present . Different plant species have different lighting requirements, so you would need to be more specific about what you are growing and what you are trying to achieve.

What will you do with the seedlings? Will you finish flowering them indoors? Will they go outside to grow? Do you know what spectrum you are trying to achieve?

Hi,
Thanks for all your reply. We are growing a lot of flowers, many kinds.
We finish the seedling outdoors.
Do you know what spectrum you are trying to achieve? No, i don't know, i just what to save money here!!!

THANKS

If you're just trying to save money then you can use just about any LED you can find. Generally speaking 4000K LEDs are a good alround spectrum from growing seedlings if you don't want them to stretch too much. We manufacture dedicated propagation LEDs with UVA, but they are not cheap.

Thanks,

I will check this...
I need some one with IP67 rating.
