In the past, everybody thought high GH & KH are not good for many delicate plants, thus we all s'd maintain low KH & GH.
Then we understood that the real problem is with KH mainly.
What is the problem with high KH (if there's one)?
Why do you (TOM) mention here from time to time that high GH is even betterr for plants?
Thanks.
