[QUOTE="SICC";2005127]are they in rock wool? i kno that the absorb water pretty good, so with the constant pump on, that might be the problem, you need to put them in the grow sponges,[/QUOTE]
no rock wool
the 2 i bought came in organic sponge. I had to trim down the sponge so i could squeez them into the little plastic fitting. My best guess would be that the were to tight. all of the clippings I've taken are in the sponges as well. Hope fully they survive
