1. every day at least, if not 2wice a day

2. great idea. fluoro, mh, hps. If you only do a grow at a time. You can combine mh and hps during flowering

3. yes, germ your seed as always, I would use rapid rooters or rockwool starters 1"x1" or 1.5"x1.5". then all you have to do is insert into hydroton filled netpot.

4. yes, I assume you are talking about the 3-part kit they sell on ebay...gh* are great nutes.
*as are Advanced Nutrients and Botanicare organic nutrients...I use all 3 companies products

well there are 3 opinions for you...goodluck lw
