To be honest it's not something i've ever dabbled with.
I keep it pretty simple for myself, grow, bloom and molasses. All organic.
But my local grow shop swore by powdered nutrients, and my friend also said he saw a difference when he used a booster very similar to cha-ching.
He didn't do a comparison though, so it could have well been a placebo for his views on his plants.
Try it though and do a trial on plants with and plants without in your grow, and let us all know your opinion.
