Vermiculite – a natural helper for healthy seedlings
Vermiculite is a 100% natural mineral additive that improves substrate properties and supports plant growth. It is light, airy, and has excellent water absorption.
Why is vermiculite the best choice for soil blocks?
In our experience, vermiculite is the best additive for making soil blocks and even outperforms the popular perlite in this regard. It consists of fine, light flakes that do not get stuck in the soil blocker – and if they do, they easily crumble under pressure because they are soft.


- Maintains ideal moisture – retains water and releases it gradually to the roots.
- Protects the surface of blocks – a top layer prevents drying out.
- Supports germination and rooting – seeds remain in evenly moist conditions.
- Aerates the substrate – improves its structure.
- Contains minerals – magnesium, potassium, calcium, and more.
- Alternative to perlite – with better workability for soil blocks.
WARNING: If the substrate already contains perlite or sand, do NOT add more vermiculite – the blocks may not hold their shape.
We recommend using a finer substrate without additives that could block the soil blocker. You’ll find tips in our guide.
