Huh. I've never had the substrate settle that much. Usually I'll gently put the substrate into the jars up to the bottom of the threads and tap the jar on the counter so it's level and settles a little, to where I want it to be. Once I've wiped the inside of the rim with a dry paper towel, I add dry vermiculite up a little ways past the top of the jar, so it gets just a bit compacted when I screw on the lid. How does that compare to what you did?
That's exactly what I did. Even down to leaving it a tiny bit of the dry stuff mounded before placing the lid on top. Go figure. Next time I'll use the medium vermiculite. Maybe that made it settle more.
Either way, with 10 jars I'm hoping to see some white in my near future.
Thanks again for all the replies and all the help. I owe ya'll a beer. LOL
