both ones really require clones while some have used feminized seed for scrog it is much better to use clones they do not all have to come from the same mother plant, a scrog consistanly outperforms a sog on yield while it does require more effort and time to train the plants it is ideal for smaller lights like the 400 hps that doesnt have really good light penetration or in rooms where plant height is limited.
so given you start from seed lets say you plant six and grow them to about 4-6 weeks old sex them and you end up with maybe 3 females take about 4 -5 clones from each female plant and succesfully root them in about 2 weeks and flower them in a sog or scrog at 1 or more plants per sq ft of screen you would probably be looking at about 4-5 months from start to finish if everything goes just right could easily take longer if something goes wrong. while you could use one or 2 plants to fill a large screen there is no advantage other than having less plants, the disadanvatge is you will have to veg the plants for quite a long time for the one or 2 plants to fill the screen area wich can easily add another month to it if not more scrog does good with indica and many indica and sativa crosses.
the 400 does not consume that much electricity and if your choices are the 400 hps or flouros would probably use the 400 hps even for veg stage at 8cents per kw hour it will raise your bill by about 30 dollars running it non stop so you can figure half that for flowering there is other stuff like fans ventilation that will add to the expense though.
would expect ozone generator to be the best but it can be bad for you and the plants if not setup properly.
