Is there a ascophyllum nodosum expert in the house?

[Wyatt Terp]

Powdered soluble ascophyllum nodosum has potassium ratings in the 10-20 range while liquid versions tend to fall in the 0-2 range.

What happens during extraction, dehydration, fermentation to produce the higher potassium levels?

What ascophyllum nodosum version works best with drip emitters that operate at typical 2-8 l/h flow rates?

Thx in advance!
