Know before you buy
Yes, rockwool is naturally alkaline. You should soak the cubes in water with a pH level adjusted to between 5.5 and 6.0 for a few hours before use to ensure the environment is optimal for your seeds.
Yes, the plastic net cups are durable and designed to be reused. Simply clean and sanitize them thoroughly between growing cycles to prevent the buildup of algae or pathogens.
These cubes are excellent for both. The fine texture and high moisture retention provide the stable, humid environment necessary for cuttings to develop healthy roots during the cloning process.
The 1.2-inch cubes will sit inside the 2-inch net cups, but there will be some space around the edges. It is recommended to fill the remaining gaps with a growing medium like clay pebbles to provide extra stability for the plant as it grows.
While designed for hydroponic and soilless systems, you can use these cubes to start seeds for soil gardening. Once the roots have established, you can transplant the entire cube directly into your soil or garden bed.
