Activated Charcoal Which to Use, Pellets, or Powder? Ratio?
Kirstenstarted grow question 1y ago
I'm just about to make up soil for this run and I'm mixing up what ammendments I'll use.
I have some activated charcoal sitting here doing nothing.
What to use, Pellets, or powder? No slate type available. Ratio? 1 cup per 1 cubic foot? Thank you so much! 💓✌️💚🙌🧡

Activated charcoal in powder form does not typically leach through soil; it remains on the surface, even when watered. Its porous structure allows it to absorb substances, like pesticides, but it doesn't dissolve and move downwards. While it can be mixed into soil for various benefits, it won't leach.
1 gram per 100 ml of liquid to 2-6 grams per liter for solid mediums. The specific ratio may vary depending on the blah blah blah.
