Is it okay to package seeds in a plastic little zip loc baggie???? I always thought that plastic was not good to store them in because of the air, etc. My friends tell me that they should be stored in paper. Does anyone have the real scoop on this??? I would like to know. I have sent away for some seeds and they arrived here in the plastic zip loc type of baggies and I wonder if they will be okay. Please advise...Thanks all!!
