Sophronitis coccinea Seedling: Slow Growth Is Normal

Seedling Pace

All orchid seedlings grow very slowly—1.5 years from flask to small plant on slab is typical. Your success so far is commendable.

Slab mounting is correct for Sophronitis. Cool nights (mountain Israel) suit it perfectly.

Continue current care.
Acquire a blooming-size plant to test your conditions while seedlings mature (3–5 years to flower).
Patience—reward: brilliant red flowers.
