coco is full on hydro. you can feed several times a day at full strength. here's some coco info.
COCO COIR
is a product derived from the husks of the coconut.
Visually it looks like peat.
It's air capacity is about 30%.
Coir is most suited as a run to waste medium.

you're prob. better off in coco. that moisture control crap probably has loads of vermiculite in it. i don't think vermic is a good idea, ever. you want your medium to dry up between waterings/feedings. remember that coco is hydro so adjust your ph accordingly.
the filter is probably good to use. some filters are designed to be re-fillable. i have a mountainair that is that way. even if they're not made that way, i believe you could drill out the rivets and re-fill it. how much filter you need has to do with room size and the strain you're growing...

at 2 weeks you can start feeding at 1/4 strength. if they're showing defs. then feed. i wouldn't foliar with the light on. they sometimes burn and you want to take care to not get your light wet. foliar feeding is best done about 30 minutes before lights on.
