Im going to try 12/12 from seedling as a test, I know its not going to be a giant grow but its better than nuthin, Its going to be LED Christmas lights, I Dont know what to do I just made the led panel Its going to be grown in an extremly tiny space (about the size of your head) i know its possible to grow in it, BUT Should I grow 12/12? Or 24/7 lighting because its kinda low powered... lights are Red white yellow, it kinda makes a reddish color mixed together.

thanks for ur help
You'd be better off writing Santa a note to bring you some bud.
If you want to grow even one small plant, you're going to want not less than 40 watts of light per square foot of canopy (ie floor) area. 70 is better.
A typical 100 LED Christmas string draws 4 watts.
So unless you plan on using 10- 100 bulb strings, in your tiny box, you're wasting your time.
Even if you are planning on using 1000 of these LEDs, you're still wasting your time, because the light spectrum these LEDs throw off is not good for growing plants.
Do yourself a favor, throw away the LEDs and put in two 23 watt compact flurorescent lights instead, making sure to also install a fan to ventilate your space.
Then, at least, you'll finish this grow with something OTHER than a few spindly leaves.
What happens if you don't give your plants enough light? Well,
a. They start to stretch towards the light, using up all your available space, in the meantime growing all stem and no bud.
b. You get no yield.
