What’s the difference between black seaweed extract powder and green seaweed extract powder?
1：The contents are different.
The black seaweed extract powder contains 18% Alginic Acid, while the green one contains 40%.
2：The usage and precautions are different.
When spraying on leaves, if you use it on strawberries or other brightly colored fruits, the green seaweed extract powder can be sprayed directly on the fruit without any problem.
But for the black seaweed extract powder, please avoid spraying it on the fruit to prevent the surface from getting black stains.

Our green seaweed extract powder is derived from Sargassum, Ascophyllum nodosum, and Enteromorpha, combined with 10% small peptides (amino acids).
