damn dude, that sounds very dangerous. I appreciate your enthusiasm and creativity, but I truly suggest that you either don't grow until you have a suitable place, or go back to the drawing board. also the fishtank water idea sounds gross and unsanitary, unless you pass the water through a reverse osmosis filter first (and probably boil it too, lol).
yes you can pump water in and use a drip regulator and be fine, but what about ventilation and temp/humidity?
the plants will often drink any excess water in their dish, but unless they are really vigorous it could overwater them.
in terms of nutrients you need to do some homework, the medium effects this a lot as well. the foxfarm line is decent, but doesn't work for every plant necescarily.
and as for light cycles, that's some really basic shit. Read the whole FAQ, really get into the knowledge. I don't doubt that you'll grow some sweet nugs eventually, but I am sure that you haven't thought this out enough. good luck
