Weedhound, I have three WW seedlings, also from feminized seeds, and this time from a better company. They're only about 3 weeks old but I put one in the dark yesterday. I'm really anxious to see if there's a difference. We'll keep each other posted. None of the other varieties has been affected, at least not so far, and most are older than the WW. I'm going to keep a close eye on everything, though. When nanners start popping up, how long is it before they pose a threat to everything else? I would think Reverse would at least stop them in their tracks, at least that's the impression I've gotten.
