My First attempt with Rockwool. My clippings Root, To Carry on their Genetics. Slightly Easier for me, with the Rockwool Cubes, added Benefit, for me at least. Cut a little branch, scrape the outer Skin/Bark/Layer about 1/2" Up the stem, some Rooting Hormone on the stem, into the pre-soaked R-Cube, then into a Cup Half Filled with R/O+ Water, week n' Half later, decent Root system, into some dirt to grow :) Not Hitting 100%, But it is my first time using, I'll need Another chance to adjust some Variables, then God willing, it will be better success Rate, I'm certain of it! :)

Value for money

I've purchased a few different rockwool products from different sellers and so far this is the best bang for the buck. This has performed as expected and the exact same as other more expensive rockwool cubes. There is no real difference so why not get more for less. I'm not sure why there is such a huge price different between different companies and why there are different sized sheets that are more expensive.

I am really pleased with these growing cubes. They absorb immediately. They maintain structure when seedlings have advanced so you can easily pull them apart (no need to separate them before seeding and soaking). There is no netting residue left in the ground after harvest, like the “pucks”. I have them in my shopping cart to purchase for next spring !!

It’s a winner!

I tested three mediums and this was the only one to work. They work for seeds, clones or random plant cuttings but I do use an aqua cup to keep them bound. They constantly perform over and above the three mediums I tested.
Highly recommend

Does what it is designed for! Absorbs lots of water and stays wet. Perfect for my tower garden. Yes, some holes could have been made better but it is so easy to make one that it does not really matter! They don't swell much once fully soaked.

Shed little fibers in the water

Of course, it is rockwool so no surprises there but using this in small aquaponic projet, I noticed that there was a lot of fibers in the water from the frequent up/downs of water.
Maybe in hydroponics it is not much of a concern.

They have little to no hole punched in them sometimes but I just push a bic pen in about a quarter inch and voila! They work just fine and more reasonably priced. As long as they stay at this price point they're a good deal.

My only complaint with these is that if they were packaged smaller, and if they are easier to pull apart. They are perfect for my hydroponics tower will most likely order again in the future.

Product came as advertised and with no damage. I kinda expected it to be a little beat up as I've ordered rockwool online before. No Problems from these guys. 10/10 happy.

Second time buying this. Works great, I do recommend soaking in water a bit first then add plants so it can puff up a bit. Or else sometimes the plant falls out.
