Charcoal to remove salts and such?!?

[whatsthatsmell]

so i was in the local agway (nursery) and i saw this product that was charcoal, and the instructions said that it helps with draining and removal of salts and other impurities in the soil. My question is, has anyone ever tried that and if so how effective. I'm wondering if that would help with flushing, but then also it would maybe effect the pH of the soil as well..... any thoughts on this?

Just stick to flushing with water.
Charcoal is often added to orchid mixes, but not necessary for cannabis cultivation.
The only things that will really help with flushing are chelating agents such as clearex.
