Must be why I’ve only had root rot/stunting issues with rockwool, it’s so perfect.

I don’t know what the best thing is, but Im avoiding using rock wool as much as possible because it is not the best.

Rockwool just holds a lot of water. It can be bad if you let them sit in a tray of water. Nursery trays have ribs on the bottom to keep seedlings and clones from sitting directly in the water. I used rockwool for many years before I went to aero cloners.
