I don't know about the mold, however the water in the cloner should be closer to 76f-78f. Ph is alot of people have good results with anything between 5.5 and 6.3. Its wierd that they wilted after 11 days? You outside temps is fine. If something was wrong with the cloner I would assume it would've wilted before that. Did the pumps shut off at all? It happend to me once:jointsmile:
