Make sure you did not have any issues with the roots from the earlier grow. If there was any wilt/root rot happening you should sterilize the medium. I always sterilize the medium, the reservoir, and anything that might touch the new crop as a matter of standard practice. Due to the porous nature of hygromite and hydroton, the possibilities for negative bacteria to linger is a real possibility. I wash the medium in warm water with a small amount of chlorine bleach, then rinse and rinse again with a H2O2 mixture and then clean RO after that. The trick is to make sure all the medium gets dry. I spread it out on a warm surface in the sun and wait until it is very dry to the touch. Expanded clay is a great medium and economical because you can reuse it. Just like with everything, it needs proper care and maintenance. Good luck; of course this is just my 2p.:thumbsup:
