Well, it is that time of year again at Springtide Seaweed: pre-order time for seaweed seed, dried seaweed, and wet seaweed. We'll have USDA organic seed for dulse, sugar kelp, alaria esculenta, and digitata. Dried organic sugar kelp and alaria are also on the menu, as is organic wet sugar kelp and alaria. Pre-orders limits: seed-none; dried-5 tons; and wet-100 tons. Seed is paid for upon ordering, while dry and wet seaweed is a 50% deposit with balance on delivery. Message us with any questions: [email protected]. Time to grow some seaweed!
