VIVOSUN 1.6" Rockwool Cubes, 112 Plugs Stonewool Starter Grow Cubes for Cuttings, Cloning, Plant Propagation, Seed Starting, Hydroponic Grow Media for Vigorous Plant Growth, 4 Sheets of 112 Plugs

I like these easy to use did not fall apart. This is a nice size. Will purchase again.

Couldnt get anything to grow in the name brand sponges, but these guys were simply easy. Size is perfect for a net cup, quality seems good, water retention and absorbtion is good. WIll buy again when needed.

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.

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.

Acquired to try this product. Tried some clippings (i also acquired Clonex as suggested) - tried 12 - ZERO rooted. All Died. Tried a 2nd time with more clippings and tried seeds - 1 seed popped - then quickly died. all clipping died and seeds also didn't germinate. Ensure to fully read instructions and checked a few of the success reviews - nothing worked. So the title of the review is accurate. These things literally were garbage. I gave this company money to be shipped garbage since that's where the product went. Even with an exorbitant amount of reading and research; Caveat Emptor. Couldn't even salvage the scraps to send back for a refund as the 2nd batch completely got molded over. Would not recommend at all. Suggested you just use potting soil where 90% of the time both snippings and seeds germinate for me personally. One of the biggest wastes of money i've ever spent on a 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.

Product far exceeds other like products we have used!

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!

Tel que décrit et tel que sur les photos.

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

Fauls advertising. Came in one single package so once open they are all exposed. Photos make it seem as if it 8 seperate sheets
