Humboldts Secret Supplies (HSS) begins with the story of Ben Garber. He was known for producing the best flowers in Southern California, and after a run-in with the law, he changed industries. Now out of the growing game, Ben saw a need in the nutrient additive marketplace. He wanted to make an additive so good that it could be used as an All-In-One additive, consolidating multiple additives into one. After a lot of hard work he developed a product and named it Golden Tree. The name made sense, because any tree that got a taste of it would turn to gold for the grower.

Im a really big fan of this Ca/Mg/Fe supplement. I decided not to go with Advanced Nutrients because honestly their Ca/Mg/Fe supplements was much too expensive in my opinion. Humbolts Secret was very reasonably priced, and the concentrate came with no precipitation in the bottle what so ever. I was seeing some precipitate around day 5-7 of nutrient solution being made but that's to be expected since the whole solution is in a dynamic equilibrium with the solutes and pH buffers. Really great supplement to have strong and resilient plant development.

Killer but mostly hype for the price. Sooner but worms casting and seaweed extracts and use those as an additive.
