hi mark ..I am also known as mark and strange enough I have also just started my own hydroponics unit. I have also have some pics in the works but they are not ready yet. I looked at your unit and it is much more elaboret than mine. I set mine up for about $35 dollars and was amazed at the rapid growth that took place and that is still taking place in the first 3 weeks of planting some starts in the unit my plants have almost grown to four times the size boy was I amazed I am currently using a version of the flood drain unit for circulation I used a submersable fish tank pump and a small inexpensive fish tank bubbler. as with yours I am able to enjoy the long light hours available with the indoor hydroponics units and the one aspect that I really like with the unit is that you have no mess from the dirt and when you need to change the ph ( with mine is almost never) the change is almost imediate unlike dirt where you have to wait to check the ph and then tinker with it to get it close to 6.5 ph. well thats about it for today. happy growing may el grande always smile upon you and the diablo winds never visit you. hot regards also mark chile head gonabe mark roache corvallis oregon 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.
