Doing it this way, as you know, the strain will defintely degrade. However, if you make a culture, using agar or, the simpler but less forgiving honey tek, you can keep that culture going forever. Just transfer a wedge of agar / few cc's of honey water/ mycelium solution, to a new culture jar/dish. The Honey Tek is under Grow/Find if you want it, this is the way to go IMHO, I am trying to do the honey tek right now, starting a new jar soon.

So degradation of the strain occurs when starting from the previous generations spores every time?

no way! it is mycelium to mycelium transfers that result in strain degradation.

Senescens does eventually occur when starting new generations from the spores of previous generations on the same substrate indefinitely. Senescens can be avoided with a few strategies. Culturing spores onto agar and isolating the dikaryotic growth is a good way to ensure a vigorous culture. The cultures can then be stored at 35-40 degrees for long periods of time. Every six months, the cultures should be transferred to an alternate agar formulation. Using this method meticulously, strains can be preserved indefinitely.

I would imagine that varying your substrate for successive generations might work nearly as well, but having a tissue bank in reserve is a safer bet.
