hey, dwc is a pretty simple way to go and with a little care and attention you should have some success.I found this for you,
DIY Standalone DWC Bucket , it seems like an easy build.The only thing I would really change would be to use a black bucket to begin with-all that tape seems like a pain in the ass, and you can get mesh pot type lids that fit 5 gal buckets perfectly to cut down on some construction if you wish, it will also give you more room for hydroton than the method shown.If you dont want to make it yourself you can find fairly inexpensive setups at pretty much any hydro store site.as for nutes n such do some research,find out what is available to you locally and ask the guys at your local shop what they have had success with, then chose from those.
good luck and dont worry if you fuck up your 1st grow-most everyone else did too
