Disa Crassicornis

5 seeds

Difficulty: Very high — seeds normally require sterile flasking.
Best method: Sow in sterilized medium indoors under high humidity & moderate temperatures.

1. Seed Preparation:

   • Orchid seeds are dust-fine. Do not soak; keep dry until sowing.

   • For best results, seeds should be flasked in sterile media (professional or lab culture).

2. Growing Medium (Home Attempt):

   • Use fine sphagnum moss + perlite (2:1) OR fine peat + sand (2:1).

   • Rinse and steam-sterilize if possible.

3. Sowing:

   • Spread seeds on the surface — do not cover.

   • Mist lightly with distilled water.

   • Keep in a closed container or humidity dome to maintain moisture.

4. Temperature & Light (Gulf Adaptation):

   • Day: 20–25°C

   • Night: 15–18°C

   • Avoid Gulf heat — indoor growing only, A/C room recommended.

   • Bright indirect light, never direct sun.

5. Humidity & Watering:

   • Constant high humidity (70–90%) but avoid water pooling.

   • Mist with distilled or rainwater only.

6. Germination Time:

   • 6–12+ months to germinate; seedlings grow slowly.

7. After Germination:

   • When tiny green dots form, gradually increase airflow over weeks.

   • Transplant only when seedlings have multiple leaves — very delicate stage.

Tip: Gulf growers usually succeed by sending seeds to a lab for flasking, then raising seedlings indoors.
