Theres a number of Hydro sites Online Fred,I used to subscribe to Maximum yield before it became an internet mag,been to a few hydro tradeshows in the past,you could probably get almost anything you wanted equipment wise from Hong Kong Hydro,its where a lot of the european equipment is sourced as the chinese are flooding the market with NFT systems,HPS growlights etc,I was told of a small hydro store in manila,cant remember exactly where now,he had some equipment but its not big business yet in Pinas,surprised really as once you get a hydro garden dialled in it looks after itself with minimal care
