I may be wrong but if I were you this is what I would do.

1. What are the light / dark times from seed to harvest time?
( is there some kind of chart i can find or a link to one that shows from first planting a germ'd seed to harvesting? )

when the seedling emerges from the soild 24 hours of light is good for veg but for good strong root growth 18 on and 6 off is best but slows down growth rate.

2.) how much should i be watering my germ'd seed in the rockwool until i move into the aero system ?

keep the rock wool moist but NOT saturated.


3.) what are the signs that i know the seedling is rdy to go into the system and then signs to know when to enter into flowering lighting stages and so on?
I dont know as I dont run an aero system, but i would say put it in asap when it comes up and gets its first real set of leaves.
then its also ready for the flowering stages when it has 4 or more nodes or about 12" high.
