I would say the easiest way to keep your music if that's all your worried about is to back everything onto your ipod you can do this on your IPad 2 also. Then there is a program called iRip, fuckin amazing lol. Allowes you to take everything from your iPod or iPad onto your hard drive, unlike itunes.
Also I noticed that your talking about using the tables, are you trying another system or have you done this before? Also do you think that the tables could produce more then the ebb and grow? I'm curious because I ran the tables for a little, and I just didn't like how much water it took up before the tables are full of water. I had to keep a 25 gallon resi for just 1 table(3x3), IMO stupid.. But then again, it could be better I just wasn't using it to the full potential so I thought it was kind of a waste.
On a flood table per plant I would average about 2 to 3 oz a plant, and stick about 8-9 girls in 1 3x3 table. Now that I'm using the Ebb and Grow I put 4-5 girls in the same space, and I'm wondering which is going to produce better over all.
