Those are all great points and observations...Kludge..god research man.However,you can prevent the peels from rotting and becoming too nasty by changing it out every few days..And by opening the bag more times.Also,Kludge,you found out the vegetable that I was reffering to.It was cucumber,and yes,it increased female ratios.The way I see it,it cant hurt to try.And Ethylene is an overlooked substance when it comes to horticulture.I say,more people try this method,and document the findings.Who knows,if in a years time,applyng this method will the the "norm"for female seeds..and everyone will be doing it to all their seeds!
