You know, I have six going right now and the 3 youngest ones are giving the highest tds reading- 900 in and 1600 out- and are looking the best!...strange. Most would say leave them alone but its just unsettling.

This morning I began the flushing process to try and reset the values. They call for a lot of water. This will take a while.

What sold me on coco is a video I found on youtube. Look up Canna Coco and watch the 3 part video. Good stuff.
