Review: Great product - Great works really good for hydroponnic systems and in table top models good seller fast shipping
Review: They Do Exactly What They’re Supposed To (Which Is the Point) - These rockwool cubes do the job as expected—and honestly, that’s exactly what you want. They’re uniform in size, hold moisture well without getting soggy, and drain properly. Seeds and clones take to them easily, and they’re simple to work with whether you’re just starting out or already comfortable with hydro setups. No weird odors, no crumbling apart when handled, and they stay intact during transplanting. I also like that they’re consistent across the pack—no oddly shaped cubes or density issues. They’re not flashy, they don’t promise miracles, and that’s a good thing. These are solid, reliable rockwool cubes that perform the way rockwool should. If you need dependable starter cubes and don’t want surprises, these are a safe buy. Sometimes “boring and works” is five-star behavior.

### ⭐⭐⭐⭐ Good, but a bit too small
*by M***Y on October 25, 2025*

These rockwool cubes are great for starting seeds and cuttings. The material feels high quality, soft yet firm enough to hold its shape, and the water absorption and air circulation are excellent for healthy root growth. I like that they are easy to cut and transplant without falling apart. The only minor downside is that adjusting the pH takes a bit of effort. Overall, a reliable and effective product for hydroponic gardening.
