I have an easy seed starting mix that uses common ingredients I had in the greenhouse. 1/2 brick of coco coir, 2 cups of vermiculite, 2 cups of perlite.
First decompose the brick of coco coir in a gallon of water and then mix in the vermiculite and perlite. It should be moist but not soaking wet.
I add a cup of Milorganite for minerals and nutrients just because I love Milorganite. I've been using it for fifty years.
Best of luck with this year's germination.
