I posted this as a reply to one of Sean's posts, but thought i would bring it to the top for more discussion:
In one of my seedling tanks, i noticed that almost overnight, pads were rotting from fungus. of course i panicked, too much time and money goes into this extravagant hobby of mine. i picked all pads that were bad and introduced a small amount of fungicide into the water and have been spraying the pads with a light solution of the same.
it seems to have stopped for now but some of the pads are slightly distorted, not sure why. the other tanks are fine. hopefully i can get them all out into the greenhouse next month.
I would appreciate any help i can get on this problem. last year i lost a batch of seedlings in only a few days to the rot.
