VIVOSUN1.6" Rockwool Cubes, 28 Plugs Stonewool Starter Grow Cubes for Cuttings, Cloning, Plant Propagation, Seed Starting, Hydroponic Grow Media for Vigorous Plant Growth, 1 Sheets of 28 Plugs

I used these to clone my plants and they do a wonderful job of keeping your clones well hydrated. I suggest using this over other products. It has been really effective and a great away to make it an easy experience when it comes to cloning plants. I dont have to stay on top of the watering multiple times a day.

good product!

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.

I use these to start any seeds I plan on planting outside in pots or in the ground. Sterile and easy to use. Also use a seed starter fertilizer as these are made from spun rock and have no nutrients in them at all.But like they say, wear gloves when handling. Easy to cut, shape, or seperate as you need.Highly recommend them for gardeners who start a lot from seeds.

Save your money! Shop around total rip off 👎 should have come with a warningStink’s an a lot less product for the money

They work but I've never used Rockwool before, Is this stuff supposed to be like fiber glass ? Either way I used them with success soaked in 500 ppm hydro nutrients water. Pops seeds and roots clones then can go into whatever medium you're using after that.

this is excellent product

These work well in our hydroponic vegetable greenhouse
