So I checked and ayup, same stuff used for insulation (rock wool0 in walls. This product is not biodegradable and lasts forever. Use a mask when trimming and gloves, also goggles to keep it out of your eyes. It is similar in handling to fiberglass, and if you use it, be sure to reuse as many times as you can before throwing them into a landfill. And Yes, it IS all natural materials that are modified, but it never breaks down.

After I soaked the Rockwool plugs, I buried them almost half way into the clay pebbles which were kept almost entirely covered in water. The container holding the plugs and pebbles had holes drilled in it, and this container was placed in another that held the water.From what I can see, I got 100% germination of the watercress seeds, and they seem to be happily growing so far as you can see in my pictures. Although I believe any seeds would germinate on these starter plugs, you may want to choose a different growing medium if you are growing plants that you want to separate later or plants that you want to grow outside. With this growing medium, it would be difficult to separate plants without losing some of the roots which would be detrimental for the plants. If you want to separate plants, it would be better to choose a growing medium that will allow you to easily lift out the plants with little to no damage to the roots of the plants.UPDATE 07/11/19:Using these Rockwool plugs for my watercress, the plants have doubled in size in a week. The 3rd and 4th pictures were taken one week after the first two pictures. By burying the plugs half way into the pebbles that are kept under water, the plugs are kept constantly moist and my watercress looks very happy.UPDATE 08/04/19:The 6th picture was taken about 3 weeks after the 5th picture, and I have already harvested enough for 3 salads 5 times. This watercress is growing almost faster then we can use it.I hope this review was helpful for you.
