Hi, everyone.

This past weekend, I was talking to an experienced orchid grower (22 yrs) and he mentioned that he does not use charcoal in any of his potting mixes. He stated that wile charcole does act as a filter, it also retains all the bad stuff that should be flushed from the potting mix during watering.

This confusses me because I see charcoal in almost every commercial potting mix on the market and I use it because it helps with drainage.

What are your thoughts?
