Re: long term herb storage

 The herbs i've got small amounts of, are still in their plastic bags in a tupperware box. Some of the larger amounts i have, are in tupperware, in a dark cupboard. Is that okay?

As long as you are intending to use them soon and not store them long term then this is fine. Plastics are more permeable to air and so the herbs will oxidize faster if stored in plastic as opposed to glass.
