{"product_id":"charcoal","title":"Charcoal","description":"Charcoal is often used as an additive to orchid mixes as it helps with air flow in the medium and does not biodegrade quickly. Certain genera (when watered often and\/or when grown in high humidity environments) can be grown in pure charcoal. We have had success with Vandaceous orchids, Angraecoids and even Psychopsis in pure charcoal!\u003cbr\u003e\u003cbr\u003eMixing recommendations:\u003cbr\u003e\u003cbr\u003e#3 - medium charcoal.
