Soil blockers are simple and effective tools which help you to raise healthy seedlings which can be grow on to advanced stage plugs, and planted out when conditions are right. They limit 'shock' from root disturbance and reduce your reliance on plastic trays or pots.
The soil blockers press a mix of compost and water into small compost blocks that allow you to sow straight into them.
The Mini 4 produces 4 x 50mm blocks.
You have the option of a zinc plated or 'Eco' (light green polyester resin protective finish).
