ACTIVATED CHARCOAL vs HORTICULTURAL CHARCOAL
|HORTICULTURAL CHARCOAL, spiritlinepottry.com|
All charcoal is fired in kilns. The biggest difference between horticultural charcoal and activated charcoal is the nitrogen, argon and other chemicals added during manufacturing. Orchid growers choose horticultural charcoal because it's cheaper, and fired without chemicals. Both types of char add oxygen and absorb bacteria in standing water.

Orchid growers have used horticultural charcoal as a water filter for years.
We suggest using it with gravel in hydration trays or inside our raku orchid pots'
built-in drainage ring.
We always suggest fertilizing with care. Less is more when it comes to fertilizers high in nitrogen.
Fertilizers can build up when the water evaporates, then re-hydrate when mixing with the new application of fertilizer. Horticultural charcoal in drip trays helps remove excess fertilizer in water.
We suggest dipping the entire raku orchid pot and plant plain water before fertilizing to help avoid 'fertilizer burn', or 'salt burn'.
Dry potting medium and any unglazed pottery need to be hydrated or fertilizer will concentrate there and chemically 'burn' air roots. Washing trays as often as you fertilize also helps growers avoid 'salt burn' issues.
