Turtle - Well the wick system is what your link showed and most people I know don't call that a hydroponics system. We call it a candle with a plant.

If you are new to growing hydro you may want to grow a few in dirt and a few in DWC buckets. So you still have smoke at the end and you will see the growth difference between dirt farming and Hydroponics. If you use the same strain you can even do your own taste test and see if you can tell. Give your friends a blind taste test see if they can tell the difference.

DWC buckets are the cheapest way to get into Hydroponics growing. You still need some tools to monitor Hydroponic grows properly. You will need a good Ph pen and TDS pen as well. Good RO water is a must for a Nubie to hydro you don't want to fight your water too. Put all your energy into growing and watching the water level and Ph. Make sure you have the proper nutrients for Hydroponics too.
