3"-4" is a good space. Sometimes root rot on clones can come from the plug the clone was started in. Rockwol will get too saturated many times, even peat plugs and soil can get soaked when the water level is high.
i dont use rockwool or peat pucks for cloning, i use an aerocloner with neoprene disks, i remove the disc from the stem when putting into the hydroton
