Peat moss is horribly unsustainable!  No reason to ever use it.  Coconut coir 
is the "peat moss" of choice for sustainable gardeners, if it is practical to 
get it to your location.  It's a wonderful material, but yes, you would mix 
it with compost.  What else have people used? Has anybody tried pulverized 
and microbe soaked biochar mixed with compost?  It does not have to be 
perfect to get seeds going nicely. Seeds grow in a wide variety of conditions 
all the time. I have been in a number of situations where I did not have 
perfect seed starter or even very ideal but yet got decent crops.

I too have been avoiding the use of peat moss for the same reasons Robyn has 
listed.

Coconut coir seems like a great alternative in that it offers most of the 
same benefits as peat moss (as a seed mix/soil conditioner), but is less 
acidic and "re-wets" easier.  I have read that coir can however (depending 
where it is sourced) contain excess salts, and it might be wise to rinse it 
thoroughly after initial rehydration if you are not sure.  I've also heard it 
can require additional decomposition, and may temporarily tie up nitrogen in 
your soil mix.  If this is true, it might make sense to pre-mix this material 
into some compost (or your finished soil mix), and let it sit for a couple 
weeks before using.

Other things to consider are the extra expense and the carbon footprint 
involved in getting this material to your location.  There surely aren't many 
coconut palms growing anywhere near where I live...that's for sure!  I think 
we should always be experimenting with our own endemic substitutes for such 
products.

We don't need to create the "absolute best" seed starting medium at any 
expense...we just need a "reasonably good" mix that doesn't endanger the 
resilience and diversity of natural ecosystems, and is locally sourced.
