High gH good for plants?

I recently got purchased some barr's gH booster from aquarium fertz and a gH test kit. I really don't understand everything about gH. I know that gH is mainly compose of calcium and magnisium. What I want to know is their relationship to the water chemistry and why it is beneficial to have it in aquariums. Does it make plants pearl more? Will it plants grow to be happier and healthier? Is it beneficial for shrimp and fish to have higher gH level? Is there a dosing regiment for the Barr's gH booster?

After getting the gH Test Kit and I tested my water and I have a gH of 9. I am kinda scared its a bit high.

There is nothing wrong with a higher gh or kh. Mine are both somewhere between 12 and 16 can't remember the exact numbers. Most plants will properly grow in hard water with the exception of a small number of softwarer plants. There's a thread floating around tom barr posted some pics of his tanks and posted his gh/kh readings and he was up in the 20s if I remember correctly. And all his plants looked great.

depends on the plants of course.. Not all plants evolved in the same environment.
But most plants that we keep will need a decent amount of GH.

Calcium & magnesium is important for plant formation I believe. Plant leaves will get deformed without them.

Don't add the GH booster if your plants don't need it. Your tap water might be all that's needed.
