This forum rocks! My local retailer is a 20 year hydro Veteran who says "duh" when I present this problem. Sold me a $30 bottle of undercurrent junk claiming to prevent bio slime Which of course it didn't. My research here has led me to the great white mycorrhizal inoculant which I feed the plants all the time once they have developed a root system. I'll try it in my half assed easy cloner and post the results here in two weeks. Since nobody else put up a photo of this alien ooze it I figured I would share mine in some small contribution to this massive information warehouse.
