That looks good. It's mostly sphagnum moss and orchid bark it looks like, with a little charcoal mixed in.
I mix my own bedding by volume mostly. It's taken a little while to dial in but it's pretty much just 1/4 sphagnum moss, 1/2 med coco fiber chunks, and 1/8 peat moss, 1/8 leaf matter all mixed together. Keep practicing it's worth it when you get it right. I put a good 3 inches in the bottom of the tub and then add leaves and it keeps the moisture in pretty good. My tropical roaches love this stuff.
