Water Issue with Outdoor Hydroponics
I'm a little noob to hydroponics, but have done tons of research did fairly well with my first outdoor system. I'm using a dutch bucket system, and seems to be working good. However, I'm having a water problem. Its been so hot here I can't keep enough water in the tank. I have to fill it up almost everyday. I don't have any leaks in the plant buckets or the piping. Any advise or tricks on keeping the water/nutrients in the tank longer during very hot temps?
