Yes like
dankiestdank said, It's a personal thing.
So this is my personal addvice to you, you can take it if you want or ingonorie it or whatever.
For a first grow I would go with DWC and maybe think about going ario later.
My reson for this, DWC is easyer to set up and requres less cash, if this is your first time going hydro, you will need to perches some equipment, PPM and PH meters, Hydroponic PH Down and Up and probably ect.
As well as the hydroponic system it's self.
DWC is very easy to set up, you need a rubbermade (Light proof), (30 Gal for 4 plants) an air pump capable of pushing around 150 Liters Per hour (You will pic one up from your local pet shop cheap) and some net pots (You can make these your self, if you want to).
You can add a few extras if you want to,
an aqurem water pump is a great addition as it adds extra air and keeps the water in the rez moving.
A thomoetor, to check the water temps.
Air stones (Help break difuse air into the water)
You should get exalent results from this system, I used it on my first ever grow and got 12oz off 8 plants under a 400W HPS.
