Nope, tried that as a last resort. Put the majority in a mylar tent and put a few back in the washed, aired out PVC after they greened up, within a day they were yellowing again. The ones in the mylar are vegging nicely. Its going back next week.

It seems to be a big problem here in the UK, I think The Chinese are copying most of the top brands and dumping them on our doorstep. They are using PVC that secretes chlorine gas when it heats up, no amount of ventilation helps either. I have put the tent in a big black bag in my shed well out of the house, God only knows what it is doing to my health if it is that toxic to plants.

Hope this thread saves some heartache.

Subzero.

P.S Stinky, you might want to add "are you growing in a PVC tent" in your troubleshooter? It would have saved me alot of frustration!
