So far Im thinking aeroflow 60 with 2 A/c reflecters 600watt hps with lumitech digital ballasts. What hoods would go good with this.
I run hydro and love it, but I am also going to caution against hydro just out of the gate, especially that particular system and on a large scale. I am not really crazy about the Aero systems like you linked--they pot spacing is far too close, there is very little room for the roots and they tend to grow around the mist heads, causing problems. You also cannot raise and lower plants to maintain an even canopy. Reservoirs with water pumps in them get hot. If you want to do hydro, I would recommend looking at DWC systems, the easiest hydro there is.
Lighting needs are figured by lumens per sq ft, so you need to know the size space you are going to use before you purchase your lighting. For vegging you want a minimum of 3000 lumens per sq ft in the 6500K range, for flowering, you want 5000 lumens in the 3000K range. A 600W HPS puts out about 90,000 lumens per sq ft, so is good for a max area of about 36 sq ft. So, don't get a hood that is larger than the area the light will cover.
Ventilation is another really important thing to consider, almost as important as your lighting.
You also need to consider how much you want to grow and what kind of high you are looking for. There are tons of different strains that have different effects, from sativas that are uplifting and make you want to get up and do stuff to indicas that will keep you stuck to the couch....and everything in between.
Tell us what your expectations are, what you want to achieve with your grow and we can help you get there.
