The finest particle, organic mix I was able to find and tried is Espoma Organic Seed Starting Mix with beneficial endo and ecto Mycorrhizae. It wonderful, soft and fluffy. Easy to water, not hydrophobic at all, great moisture retention too. And for the first time, even with moisture under the dome for 3 weeks (while trying to germinate some older pepper seeds) - no "white" stuff on the surface at all, best germination results I've ever had.
The only thing I add to the mix, is organic worm castings, at the ratio suggested on the package (3 parts mix to one part castings), which also happen to have 1-0-0 NPK.
I know that we all have our favorites, but this mix I absolutely love for the seed starting. And seeds seem to like it to...
My second favorite is still Jiffy #7 pellets.
Regards,
D
