This is for making seaweed meal – not a seaweed meal that you sit down and eat, but a fantastic additive for the garden – and especially tomato plants and potatoes. The raw material is sun-dried seaweed, gathered from well above the tideline – 1) because when you carry home wet seaweed 5/6 of your burden is water; 2) because dry seaweed is much pleasanter to handle; 3) because compost shredders much prefer dry seaweed; 4) because the resulting fine meal is so easy to distribute, and starts breaking down and thus releasing its goodness soon as it is watered.
