I was introduced to SuperThrive about 10 years ago. What is really strange to me about it is what the smell and color of the liquid itself does to me when I open the bottle. It really, really
reminds me of a vitamin liquid (identical smell and color) that my mom in the late 50's used to make us take by the spoonful whenever she remembered to give it to us. She said it would be good for us and I believed her.
OK enough nostalgia...super thrive is not a fertilizer it is more like a vitamin, rooting enhancer, foliage and flowering enhancer. It is something you would add to your fertilizer or just give to plants on its own in between feedings. Analogy would be fertilizer to plants is like food to humans. SuperThrive to plants is like vitamins to humans. I have used it for over 10 years mainly to help strengthen my semps for the winters when I was living in New Mexico.
Back to the beginning, I think Super Thrive had some of the same ingredients of that vitamin that my Mom fed me by the spoonfuls in my early life...crazy, I know....
