Everyone starts the same way as you... it's like at first we don't even expect the seed to germinate, then it does. Then we expect it to die within a few days, and before you know it it's grown into a substantial plant... Then we think, EXPANSION!
It's great that you're thinking about making the jump to aero already, but a far easier option would be a DWC unit. Whichever path you decide to take you will need some essential tools, one of them is a digital ph pen so that you can accurately measure the acidity level of your feeds.
You can buy a pen here:
