LED light for indoor

Hello Thank you for guiding me to grow a strong and beautiful plant. I use LED light for indoor planting. The light power I use is 3000W consisting of 20 LEDs / 150W with the appropriate light spectrum I designed and built myself. But I have a question: When my plants are just sprouting from their seeds and splitting their shells, how many W of light is appropriate for them? And how far should I put the light? In the meantime, how much light is appropriate for a few plants to grow fully if I want to get maximum yield? Thanks for the guidance, Iā€™m also trying to share my knowledge with others.

very nice

Can you give specifics on what you used to build your light?

I want to dip my seeds tomorrow and light the soil after it comes out, which is for the vegetative period.
