Well hello, I am onboard for this grow. Your set up is among one of the best I have seen, not only cause you clearly can afford the best equiptment, but because of the obvious work and effort you are putting in to really do it right. I admire your efforts and hope to see you get to harvest.
Sneeze who posted above me happened to say exactly word for word what I would have typed, for a first time poster he really caught my eye, needless to say after reading this whole journal i know you disagree but try what ya want and learn from it.
I have many many years experience growing is soilless medium and am happy to help if I can. Don't get discouraged at problems, they will happen, it will take experience not money to grow a good crop. Expect to fail, then any success will be a victory.
You have a great set up and room, it is a good place to start.
Also... adding H2O2 to your water will oxidize the cloramines out of the water and help sterilize it.
Feel free to read my journal, you might get a few tips.
Good luck, I will be watchin'...
