problem of damping off
 

hi ron,
what is the best method to control or to remove the problem of damping off in a hydroponic system ?
im using sponge as a medium.

Damping-off is a medium-borne fungus that rots newly sprouted seedlings right at the medium line. I suspect your sponge medium is holding to much moisture and not enough oxygen. Overwatering and to much humidity is the biggest cause of damping-off and the key to prevention.Ron
