Looking for an ancient Chinese secret

Im looking for a book about Chinese horticulture. It was written with Chinese on one page with an English translation on the facing page. One of the chapters was about cultivating marijuana, with a subheading on how to make it stronger. You added different chemicals and plant juices, some of them which are poisonous, to the potting material as well as during the feeding. It would have to be kept away from water sources, and other plants and animals, due to the runoff from watering and the plant itself being poisonous. It self pollinated, with the buds looking stunted and immature. The seeds from the plant are what your going for, with them supposedly looking a lot like a Chile pepper’s seed, small and flat, but with the characteristic “brindle” color of a marijuana seed. The whole plant, bud, stems and leaves, would then be thrown away far from any water source or dropped in to the cesspit, but never burned, due to it being poisonous. When these seeds were planted, supposedly the amount of thc would be up to double or triple the original plant. I’m hoping this community will help find this book on “ancient Chinese secrets”, since the person Who had the only copy I have seen was my father, who passed a couple of years ago, and the location of the book went with him
