Grodan SBS 18 trays x 77 Cubes – 1386 Carton

Description

GSBS – Grodan SBS 18 trays x 77 cubes (1386/ctn)

Loose 36 mm plugs in a ready-to-use propagation tray.

Grodan SBS plugs are square 36 mm stone wool plugs that sit loose in a plastic tray of 77. They are designed for raising plants from seed. Their shape and firmness make them easy to handle by hand or by machine. Every plug has the same density, firmness and fibre structure, which gives uniform germination and a high success rate. Grodan stone wool is naturally slightly alkaline, so soak at pH 5.5 to bring the plug to approximately pH 6.2. Use nutrient solution at EC 1.5 to 2.5 mS/cm for soaking. Water when the tray has lost 40 to 50% of its weight. Because the plugs are loose, you can lift out rooted plugs one at a time and move them into a Grodan Delta or Hugo block.
