3 or 4 weeks of progress with the DWC hydroponic setup

I picked up a PPM water meter so I am going to experiment with the type of nutrient mixes I am using. You can see that right now I’m using Plant Prod Ultimate from Wal-Mart. It’s a 20-20-20 general purpose fertilizer. Was mixing at 900 PPM, am going to try 500 ppm see how the plants react.
