This is a second hydroponic setup. It is a one station raft system. The water container is a CD case picked up from Wal Mart and wrapped in black duct tape. A small airstone is at the center under the net cup. The foam is recycled from a Star Wars Millennium Falcon plate. With this foam the net cup sits 1/4" below the foam. Air is provided by a Top Fin air pump sized for a 10 gallon aquarium. A aluminum hood has been made for my 5x5 LED array. This setup has the main purpose of testing the LED array.
Three days ago lettuce was started in rockwool cube the same way the Roma tomatoes were started. I used the "black seeded simpson" lettuce from Ferry-Morse. It only took two days to sprout.
This system holds 3/4 gallon of nutrient solution. I mixed it as a one gallon batch. Used 2.5 ml of FloraMicro, 2.5 ml FloriaGrow, and 2.5 ml FloraBloom. There is a little bit of waste of 1/4 gallon but that is ok. It will be put on my dirt garden outside.
