eh my 2 cents. 24 hours for the first week or until they all pop from the soil and the last one opens its leaves. (i did it that way but others go 24/7 for a month or more)

for germing itself you don't need light at all, it just needed for the sprout and for this business a little cfl with 6500K spec as you got it just fine.

Just keep it low if they show their little tips, so that the won't strech on you. no fun to bury them deeper later on

I've done this with the same lighting you are using. I used a steady 16/8. If the plants sprout up in the middle of the light they will be fine. They will get used to the lighting. I recommend going with the 16/8 or 18/6.
