Grodan A-OK 1.5" Rockwool Starter Plugs 2 Half Sheets of 49 (Total 98 Plugs) Made in The Netherlands Includes Twin Canaries Chart
The 1.5" Rockwool Starter Plugs are a good product for starting seedlings and cuttings. Customers were impressed by the fast sprouting time of 4-5 days and a good fit in 2" net pots. Rockwool cubes can be trimmed to fit and are reusable. Some customers faced issues with plants not rooting even after soaking, but the solution was to put the hole a little deeper. There were also suggestions that the cubes can be cut into quarters to multiply grow media. The cubes don't split easily but prepping them by washing and reducing the pH is necessary. It is recommended to use a clear container or flip the container upside down for natural light. Overall, it is a cost-effective product that works well in hydroponic gardening.
