VIVOSUN 1.6" 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!

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.

Lack of any reasonable density makes these less than ideal and there is not enough structure to them for any discernible holes for seeds. Spend a few more dollars and avoid this mess.

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.

I bought these so long ago I almost confused them with the ones I just bought. These are terrible, are too small and they fall apart. Way too much particulate everywhere.

I have a few plants I'm growing indoors, hydroponically and im using these plus clay pebbles in net pots with five gallon buckets, plumbing, the whole nine yards ya know. Let me say, these are the starting point, where the magic happens, the foundation from which the transformation of seed to tree takes place. Its like the bowl to your cereal, the underwear to your outfit, the uterus to a fetus. Can you have these things without a bearer, sure, but thats just an aweful and terrible idea. How would you feel finding out your were a test tube baby? I for one, would be appalled. Dont experiment with your babies, let them grow safely efficiently in a reputable medium such as these rockwool cubes by Vivosun!

These work well in our hydroponic vegetable greenhouse
