no, don't try to do it far in advance, especially if it's your first time. in the 2 or so weeks it might take the spores to get there, the substrate might have gotten kinda dried out or even contaminated unless it was in exactly the right conditions the whole time. don't bother, mixing it all up and sterilizing isn't really that time consuming.

If anything grows in the jars it is an indication that they were not sterilized properly. Proper sterilization will result in the death of yeast or fungus or whatever may be in the substrate before sterilization.

I know I'm going against the grain here but I think you should make them a week in advance. That way by the time you're ready to use them you know for sure that the substrate is indeed sterile and you don't end up wasting valuable spore solution on substrate that is destined to fail.

My mind is corrosive...

I've had jars sit around for a long time and still work fine. Make an extra jar, and open it right before you use the rest. Smell it, to find out if the batch went bad.

And it's not a question of not having the time, it's a question of eliminating the possibility of incomplete sterilization. This is always a good idea if this is your first time growing gourmet mushrooms and you wish to not waste spore solution.

I bought my jars already, and then I heard that they had to have rubber seals on them. Oops!

I use a Ramsey seal, which should be sufficient without the extra saran wrap.

It works, just do it. brf + verm are great because they're easy.
