Yes, something like that, my friend produce this, made from whole fish, very thick and smelly, they call it some sort of enzyme, I believe there are certain bacteria inside. Attracts ants, something that you don't want to keep inside your house.
Not cheap, but they show me some video on the result of applying those in corn, soya, etc. , they claimed that the harvest at least double. They even mix those into animal feed for pig and cow, also resulted into fat animals.
I got a sample, tried it into some tropical plants like jasmine, gardenia jasmine, Hoya, etc. All gave me a very good result. I am not sure if it is due to the arrival of rainy season or the juice. Planned to try on adeniums, but I can not apply those in rainy days.
Sharing the result, just applied once.
Look at the size of this Hoya, compare with the normal leaf at the back.
This small tortured plants, at this size, this treatment and this pot, it should not flower.
Lots of flower buds on the gardenia jasmine, but most of them rotted and fell-off before open, not sure why.
I didn't apply those on the C&S, worried that they will rot, except on Knuthii that I can afford to loose, also 2 gymnos and 1 melo cactus to see if they can become giant cactus, but so far I didn't see any.
