A quick germination question. In the past when using pre-packaged germination mixes like Black Gold Seedling Mix, I was hitting near 100%. Now that I'm making my own (LC's #1) I'm only getting about 50% to come up. The ones that don't make it crack, put out a small tap root, then just die. When I open up the shell and take a 20X look inside, there it always a brownish rotting inside. Thoughts?
