that is an interesting method - the bag thing. I have maybe three trays with tubers laid out. I ran out of room and figured I would let them lay and eye up or not. I may try them in the bags. I moisten my soil slightly before potting so I know that except for the top few inches that is drying out, the tuber is covered in slightly moist soil. Considering the level of dessication it has to be helpful. I have maybe five showing green/red shoots but assume those were 'eyed up' when they went into the pots. I did snip off several shoots as they were weak and twisty. I am hoping somehow the tuber either has another eye or can push out another shoot from the original eye. Have no clue
