@DaSofaSurfer, Hello and welcome. I make bocashi, using dry materials as a base, which I find in my area. For example, I have made bocashi from wood chips and right now I have fermented dry grass bocashi with Microorganisms for a week, next week I will publish the complete process of creating dry grass bocashi. I normally use my 20% bocashi to compose the new substrates for my pots.
The seaweed bocashi I buy and I think it is made from Kelp seaweed, although I also have yet to make a bocashi with freshwater algae that I have located after cleaning a nearby river.
Besides the tea I make other preparations with algae, Lacto ferment of algae with EM and Enzymatic hydrolyzate of algae, I use three types of algae that I have in powder: Kelp (Ascophyllum Nodosum), Spirulina (Arthrospira platensis) and Chlorella de hainan (algae of protein-rich fresh water).
To make the bocashi tea or worm cast tea, I use the alkaline hydrolysis method, it does not need aeration and it can be started to use from 12 hours.
Formula for a liter of water:
100g of aged bocashi or worm hummus.
1g of potassium hydroxide (KOH)
1l of pure water
You mix the bocashi with the potassium hydroxide and a little water, mix it well and wait a few minutes ... you add the rest of the water, keep it in the shade, it doesn't close ... you stir it several times during the first 12 hours.
You can keep the preparation for a maximum of a week.
After 12 hours, you can strain it and use it in irrigation diluted 10-15% with clean water. 😅
