The rock wool tray is a system for rooting cuttings and germinating seeds.
Rock wool cubes are available in different dimensions and are served on a plastic tray for better operation.
Once the stake is rooted, these cubes can be transplanted directly into the 7.5 x 7.5 x 6.5 cm cubes.
Rock wool is used as a support for hydroponic crops, because, due to its mineral composition, it is inert, therefore, it becomes a clean and safe system.
For a good use of rock wool we advise you to submerge it in water with pH (5.2 or 5.3) 24 hours before use to lower the high pH that was manufactured.
