1)Agree with Hydrotron just dont forget to soak it
2)Agree again unless for some strange reason your tray is round then I believe a mixture would work best
3)Good start would be 15 mins 4 times a day and adjust from there
4)sounds about right
5)sorry do to recent activity around here I'll stay away from that one
6)Light is a good ?? but how about ventilation and climate control
7)zero veg and less than 10 week flowering= #of plants ........... Lots!
8) you can take a rooted cutting and place directly into the tron just remember roots are extremely delicate so dont "shovel" the tron onto them.
9)what nutes you planning on using??
