Just to keep folks interested. This is a couple in Estonia. At 3:39 and 10:27 there is a little bit about seaweed

We are using it everywhere this Spring with very positive results. Earlier we pulled the straw back from our garlic and put seaweed in instead. That row after about 3 weeks is 25-30% largernand much greener than the garlic that was left with just the straw. Our greens in seaweed have greener greens and redder reds.
We have potatoes that we have mulched with seaweed and we have also just laid the seed on the ground (like Man from Anan) and covered it with seaweed.
I will learn how to take some pictures.
I can get around 80 degrees (air temperature 35F) using seaweed and wood chips.
3 months ago FF fertilizer was plentiful and cheap. Crazy how fast things change.
