germenation?

when i germenate my seeds ( using a rockwool sbs propagation tray) should i leave it in light or dark or just like in front of a window, and i assume i hould keep it near a space heater for warmth. and when i have small seedling do i need them under cfl's of is just regular sunlight ok.? thank alot for your help in advance.

i germ in the dark, once i have a taproot i plant it, wait for it to pop out of the ground then add cfls.

a seedling shouldnt have no problem handling direct sunlight even right after it sprouts out of the soil or rockwool if thats what your using, but if your using a dome it could overheat without proping the dome up to allow some air and the soil or rockwool will probably dry out quicker and need watered more often.

then i should just trans plant the rockwool into a suitable peat pot with a nuetral soil or medium, should i use any other organic fertilizers and whatnot?
