VIVOSUN 1.6" Rockwool Cubes, 4 Sheet of 112 Plugs Stonewool Starter

Perfect size for 2 in cups and they work just as they're supposed to

I don't normally use rockwool for clones or seed startng. I did this time, and was surprised with close to 100% success. Rockwood is Rockwool, but this is good and I'll buy again

Perform as expected. I prefer this size

it is what it is and it works how it’s supposed to my advice though is to cut not tear lol

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

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.

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.

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

Perfect for a Tower Garden or similar.

attention il faut ajuster le ph

Had to choose one star as no star would not let me wright. Junk pure junk , shipped as is , no box !! As I opened the wrap and started to break up the cubes they would all fall apart !!

They work well.Not much to say it's cubes of mineral fiber with a hole in it.
