White Spots on Paphiopedilum Seedling Mix: Snow Mold Fix

Watering Paph seedlings; noticed small white egg-like spots on fresh mix. Harmful? Removal?

Diagnosis: Snow Mold

Occurs when mix stays too moist/humid. Likely soil-like mix or moss retaining water. Seedlings in enclosed container? High humidity promotes it. Harmless short-term but can spread to seedlings, reduce light, degrade mix.

Solutions

1. Remove container top → lower humidity.
2. Mist mix surface with Physan (fungicide); avoid seedlings.
3. Or: soak new mix in fungicide, sanitize container, repot seedlings.
