I have not seen it listed here so I thought I might bring it up (again if not covered before. I have had problems with grows while in a HydroHut grow tent. I had written these experiences off to my dumb ass. However I have a friend that may have given me the reason for the issues. It seems the PVC coated lining of the grow tents has "out-gassing" issues that effect sensitive plants. Of course growing hydro makes all plants sensitive I believe. I have done additional research on the effects of PVC and am astonished. Subsequently I have packed up, in an air-tight container, the old tent and now am looking for all PVC made items in the home to dispense with as well.Check this link out
