S/H pot depth

I have another suggestion. When I observed my new catt root tips turning black as soon as they penetrated the medium it was not characteristic of black rot since it did not spread at all, right above it new healthy branches formed very soon and have remained healthy. Then I saw a post by Ray talking about mineral damage. Indeed the top of my media had very heavy mineral deposits. Flushing with clear water and replacing the offending pellets seemed to help. Still no real evidence of root rot anywhere else on this new root system after a month.

By the way, I think the new medium seems to take much more rinsing. I have used the same method with both new and old media in pots side by side this Summer and I did not notice as much accumulation of minerals on the top of the old media in the past 5 months.
