the substrate is a solid clump should I still inject my spores?

Mycelium can eat its way through solid wood with no problem at all. If you were to open the jar and feel the substrate you would see it has the consistency of a sponge. Your gourmet mushroom spores will have no problem at all consuming this substrate. In fact they will love it :).

How long can these stand before they dry out without any spores injected into them?

These are made fresh .and are 100 % sterile.. They are double sealed so they cant dry out in any short period. So the answer is well over a month ... We suggest using within several weeks to ensure the best results ...

How long in fridge jars last without losing efectivines and potency ? g

These jars will last several months in the refrigerator. But we make them fresh, so order when you like. We also list 12 jars for the price some listings have for three. Type in "Mushroom Substrate" in the search bar. Also, you may check out pint size Rye Berries grain jars both in regular mouth and wide mouth. There is no inflated price on these either, so Mush Love is the answer to all our substrate needs.

How do these come packaged? I ordered 6 jars. Will they fit in a standard mail box? Or should i wait on the mail man?

They will drop the box on your doorstep. The jars are tightly bubble wrapped.
