I'm trying to get the pics up now but I'm also trying to play catch up in the education department so any help would be appreciated. I have a plethora questions in the Hydroponics section.

My Rapid Rooters are pretty soaks and I'm considering dumping out the 1/8-1/4 inch of water that's left in the tray so they dry out. Otherwise I've heard root rot can occur.

Also another big problem was my water reading last night. I don't understand the uS reading. My pH is slightly high at 6.34 and the ppm was 240 when it called for 200.
