Seed raising media is used to germinate seeds in living soil. The seed raising media keeps the seeds just moist enough without being waterlogged. As the seeds germinate, their roots will pass right through the seed raising media. When the seedling has enough roots, it can be planted directly into a living soil garden. Our range of seed raising media includes Grodan stone wool / rock wool grow cubes, Eazy Plug coco peat blocks, peat pellets and foam blocks.
