I have no idea what the water situation is in China, but here the water situation is much worse than people want to accept. Been to the Hoover Dam recently? Lake Meade is down 30 feet from the high. Here in FL, Lake O, the large lake south of Orlando, is still 4' below it's highs from just 3 years ago.
It's amazing when I hear the stats about the percent of water that's used for irrigation. It's very high.
So, better systems save water, and that's the main selling point of LNN systems. Need more food? Have less water?
All this drivel says that I had bought it, then the volatility drives me nuts, but when I'm out of it, and see it move, I'm just kicking myself. I want to be back in.
It may see the hi 30's again, that would be a VG entry point for me. I'm in VMI.
