The product came on time %26 undamaged. I thought the soft, fibrous material would be easier on the clone %26 biodegrade more easily than the solid foam material I usually see sold. There is no tray with the cubes; which is OK - they didn't advertise it that way, I'm just mentioning that in case you didn't notice it. So you'll have to buy a tray separately. I was asked to review this product before I could tell if it really promotes growth, but so far so good. The one advantage I see (over the foam cubes) is that you can gently open these cubes without disrupting the clone to check for any sprouts at the tip.
