Will reorder
I don't normally use rockwool for clones or seed startng. I did this time, and was surprised with close to 100% success. Rockwood is Rockwool, but this is good and I'll buy again

Don’t fit in segmented Grodan tray
Was exited to find a less expensive product than Grodan. But the size is different than Grodan and won’t fit in the segmented trays. Other than that, quality seems okay.

Best bang for your buck
This is actually a good price. The packaging just came in plastic wrap no box but that is fine. It’s the package with the most block at best price ratio. Which is fantastic! We go through soooo many of these all the time so I am always trying to find the best deal. I do find it to be a bit stiff and not very airy like some other brands. Depending on what you’re growing this could be good or bad because it is tight in the roots. But I guess it takes longer to dry out ? The fiver glass doesn’t shred as much. This is helpful because I don’t get as much itchy skin when using it. I would buy it again and actually am going to right after writing this review

If you’re looking for garbage this is the product to get !!
Had to choose one star as no star would not let me wright. Junk pure junk , shipped as is , no box !! As I opened the wrap and started to break up the cubes they would all fall apart !!

They work well.Not much to say it's cubes of mineral fiber with a hole in it.
