Morning IDKN, I ain't the man by no means, but yes KindSoil is simple an awesome stuff all you need is water ,nutrients already in it, all you need is PHwater, an coco on top half of your pot, if not coco then any good potting soil will do.
I always use cfls on my seedlings, but you could dim your thou down real low and that would work fine, just don't put it to close to your seedlings, start around 28-30 inches high, then you can lower it after they get used to the light an growing good. GoodLuck my friend.
