Features of Rockwool Cubes
This rockwool is very effective hydroponics supplies, made of high-quality basalt, centrifuged at high speed to form fibers after being melted at high temperature, and compressed into blocks through proprietary process, soft and even texture, good water absorption and strong air permeability, which is helpful to the growth of roots.
- Warm Tips: Because the whole rockwool cube will get re-planted with the plant to avoid damaging the growing roots, you can reuse the plastic net cups, but not the rockwool cubes.

Received in a reasonable time, well packaged for shipment to prevent damage. Cut nicely with regular scissors to separate squares. Water absorption seems to be adequate. Testing for germination, using lemon water at about 5.5 to 6.0 PH with the rockwool. I grow all my plants from seed in a Christmas Gift Hydroponic Gardyn Studio (all year), Large Garage Container Garden (all year), and Raised Garden (Summer, Fall). It's important to have quality rockwool to germinate seeds, hopefully these will do the job. If germination is as good as the rockwool appears to be, I'll definitely purchase again.

Works great. The only complaint I have is that some of the holes in the media are off center.
