Pretty straight forward! They work and they hold up after soaking. Some don't. Happy with quality.

Good old fashioned rockwool cubes
These are rock wool cubes and they are the right size for what I needed. And if you know anything about Rockwool, You know that it's pretty much all the same. Anyway, these absorb liquid and hold it well. And they don't have any organic matter in them so you can tailor what you feed your seedlings or cuttings without getting anything extra in there.

The product is rockwool
I liked how it had the plastic around each square. It seemed to hold together. I'd recommend it.

Not 2" Tall. Only about 1.5"
I was hoping to get a little bit larger cube for clones to root in but the cubes are only 2" wide and not tall. They are the same height as the 1.5" cubes so you have the same amount of depth to plant the stem of your cutting in. They will work but not what I'd hoped for.
