OK tank inside greenhouse, leveled the best we could on a dirt floor, and media being added. After media added it was hosed again and allowed to fill GB for a final rince. You can see the water is dirty and makes me wonder why I wasted time trying to wash it by the bucket full. I put garden hose on bottom drain and emptied the FT to some trees outside the greenhouse.



The pump is just a little yard pond pump. I have 2 of them and the one ran 24/7 for about a yr. before I unplugged to get this system set up. There is a stand pipe in GB that provides 2 inches of top dry media. I am running this as a constant flood for right now. Not only is it the line of least resistance (easiest) I don't have the confidence yet to get into bell, or aftan syphons. Right now I just want to get a system up and functional and productive, then I will start to experiment with another setup when I have the greenhouse pretty much to myself.
