Grodan AX 25×40 Rockwool Cubes – Clean Seed Starter Plugs for Commercial Hydroponic Growers
Grodan AX 25×40 Rockwool Cubes are a professional-grade solution for growers who need reliable, uniform propagation across a large volume of plants. These seed starter plugs are designed to minimize mess, reduce variability and improve early-stage plant development. This makes them ideal for leafy greens, herbs and specialty crops in hydroponic systems.
Each cube is engineered with clean-cut edges and low-dust composition to maintain a more efficient, hygienic growing environment. The structure allows for even water distribution and consistent root development, giving you greater control and predictable results.
The sheets fit nicely into a standard 10” x 20” flat.
- 1″ plugs (1x1x1.6”) (25x25x40 mm)
- 10mm x 10mm (0.4″ x 0.4″) hole
- 200 cubes/sheet
- 6,000/case
- Weight dry = 2 g
- Weight saturated = 18 g
AX cubes are recommended for lettuce, herbs, and other greens in a NFT system as the wider base gives the plug more stability in the gutter.
