Water runs right through all my castings and it's been perfect for germinating EXCEPT that it dries out too quickly and this can kill any seedling in a days time. These castings were from rabbit manure fed worms and that may be the difference. My coffee ground castings do seem to hold more water and I would definitely amend them with sand or perlite.
Damping off has never been a problem in the castings ....unlike my other germinating mediums.
