Hi I'm new to hydroponics myself. I'm currently starting (I live in Australia) my chiles inside using a flood and drain tray setup under a 400 watt son t agro lamp that's on for 14 hours a day. I have a few pictures of my chile starting setup at: http://members.xoom.com/mjdodgson under the "Hydroponics" link. I'm planning on growing my chiles to maturity outside using a non recycling setup utilising the "smart valve". This valve works by connecting to a nutrient tank and "feeds" the valve by gravity via a thin poly tube. Once the level of nutrient has reached a depth of 30mm (1 1/6 inch), the valve shuts of the nutrient flow. The valve only opens again once the nutrient level is almost depleted, thus the plant roots aren't constantly saturated and oxygen deprived. I think the best part about this setup is that the smart valve uses no electricity. I'll probably put together a few single channel 15cm deep x 15cm wide x several meter long lengths each utilising one smart valve, all connected to one nutrient tank (probably a big rubbish bin). I've got some granulated growool to use in one length, and I'll get some grow rock to use in one, and some perlite/permiculite in another as an experiment. I'll let the list know how the experiment goes once the season proper gets going, several months from now.
