If you want a nice big plant I would also agree DWC seems a good way to go. A lot of the plants I think are toppers have a bubbling bucket below them. There is a couple of good DWC logs in the grow section so you should find plenty info available. Look forward to watching how your log goes as Ive considered the jump from NFT to DWC before and will no doubt have to add more hydro kit not to long from now.
