In a word, yes, you can grow exactly as you describe. Just make sure you're using proper hydroponic nutrients even though it doesn't seem like a hydroponic system. Hydroponics is simply soil-less growing, so you'll need exceptional solubility in your nutrients just like you would in a more stereotypical hydroponic system.
I recommend Advanced Nutrients. There just isn't anything better.

This is not true. Not all soil-less growing is called hydroponics. You may have heard of aeroponics and bubbleponics. Neither of these are hydroponics, and neither use soil. I would also not recommend growing in rockwool unless it is used in hydroponics. You can use it if you want, but it will dry out really fast, normally its used in applications that are watered frequently such as ebb and flow and drip emitter. If you are just starting seedlings in it, you can set the cubes in a tray with about a half inch of water in the tray. The cubes will wick up the water, kind of a ghetto hydroponic system if you will.
