Recommended organic plant food.
Perfect organic fertiliser to use for house plant in hot-arid climate like in the Middle East/West Asia. Rest assured that you'll not be killing your plants with chemical burns like when you use synthetic fertilisers without circumspection. And the plants love it (including cacti). It is advertised to leech out N:P:K in proportion to 2:3:1 ratio and the seaweed Kelp (Ascophyllum Nodosum) extract will provide your plants with growth hormones like auxins, gibberellins, and cytokinins. If you use the fertiliser in quantities advised by the manufacturer you'll not perceive the smell even at a foot distance and the smell is kind of 'sea-like' or of fresh fish and not even off-putting for most.
