First, you are going to need a pH meter and something to measure EC. Correct pH is essential with hydro.
Next, I am going to recommend Satori. She is easy to grow and clone and even though she has a very uppity sativa high, she finishes in only 9 weeks. During certain times of the year you can buy directly from Mandala. The last pack of Satori seeds I got, they sent a free 5 pack of Krystallica. I have tried a lot of other sativa dominant strains, but, IMO, none of them are as good and as easy to grow as Satori.
Make sure that you get a good quality air pump and air stones. It only takes about a day for a plant to die if the air pump fails or an air stone clogs.
I don't quite understand this statement in reply to Rosebud's question about incoming cool air: "Yes from the 190 cfm carbon filter at the top of the tent blowing out, so i figured it would be able to cool it enough but not positive."? Do not use your carbon filter until you need it. I adversely affects the cfms of the fan, so do not use it until and unless you need it. Tell us exactly what kind of fan your 190 cfm inline fan is. If it is a centrifuge type fan, it may be enough. I have run a 400W in the same size tent with a 190 cfm fan. If it is a duct booster fan, it will not work. However, if the 6" is only $30 more, I think that you should go with this if you can. Get a speed controller and you can run it at the speed you need. It will be a lot quieter to run a 6" 442 cfm at 50% than a 190 at full speed.
