Do you think it's normal for the others to be behind? The one is changing (a second tiny "stalk" sprouted up and she's a bit taller) but nothing whatsoever from the others.

I am not sure if I should just be patient with them or open the cube and see what's going on (possibly ruining them in the process) possibly scuff the unopened seeds with sandpaper or what.

Damn, I knew I should have done the paper towel method, these starter cubes are too mysterious.

It's dark, no drafts, the right temp and they're not too dry or too moist that I know of. It's been 5 days, which I know isn't long, but I am just unsure if one should be a couple days ahead of the others.

Any insight would be appreciated.
