    Good quality seaweed, highly concentrated , need to mix only 30 ml in 15 litre water solution , however container quality is poor and needs improvement, mine started leaking, from the bottom of container without opening the lid. Had to transfer the remaining quantity to another container .

    Got this after reading about seeweed fertilizers on google. I sprayed it on some of my citrus and other plants. My bougainvillea did have some leaf burns so did one of my citrus plant. But the plants did show some fresh growth after spraying. The bougainvillea leaves had turned paled green but now they have turned much darker.
    It you are going to use it as a foliar spray i would recommend testing it on a part of the plant before spraying the whole plant. You may need to adjust the concentrations so that there is no leaf burn.
    I like the fact that it has both the macro and micro nutrients.

    Good product . I am using it as an inter-current fertilizer along with my other organic stuff. Yet to reach a definite conclusion about the effectiveness. I would say its a good addition to your shelf if you are into home grown vegetables.
