i was reading through your list-o-stuff. i think your light is most definitely under powered. the rule of thumb is: for every plant 100w. you have 600w that equals 6 plants. and if you plan on growing white widow... that stuff turns into a bush you might get away with 3 maybe 4 in that space alone. that is one of the best strains to start out with. you should check out arjans seeds though he is the OG of white widow and his white rhino puts out more and doesn't bush out as much. your cooling and venting are right on, you have done some homework. just don't get your hopes up to quick. the first couple of crops we did didn't work out as well as we had hoped but it was a learning experience.
make a aeroponics cloner. don't use the gel. i have 100% success rate using liquid karma,cal-mag and hydroguard in the cloner. i haven't lost a single clone yet. right before i transplant them i give them a little shot of pro grow to give them a little stretch, ph5.5 ec1.6.
one more thing. were you going to use the silicone for filling cracks? if so i found "great stuff" to be the best, why you ask. because it expands and fills the cracks and light doesn't get through.

oh and if you are spending all that money on tools and supplies, why not get a hydro hut. those things are badaxx.just thought i would throw that out there.
