Well if you let it go too long it will engulf you like the Blob did to Steve Mcqueen. Need to get them plants out of there and sterilize the system. Shouldnt hurt em to hang in air for a an hour or two..in fact they say them roots love get to a little fresh air occasionally. If that contraption belonged to me I would take out the plants and run some Clorox through there to kill that chunk. Wash all the rocks etc. Rinse it 14 times and put it back together. That should work.
