Propagating Shrimp Plant (Justicia brandegeeana) from Seed

A friend collected shrimp plant seeds on holiday. Any tips for seed propagation?

Tropical Shrimp Plant Seed Starting

Shrimp plant seeds germinate at 61°F+. Surface-sow on damp (not soggy) potting soil, press lightly. Seal pot in plastic bag, keep at 70-75°F. Germination in a few weeks. Critical: seedlings need intense light—a sunny window isn't enough. Place 8 inches under a 40W fluorescent shop light. Transplant after first true leaves appear. As a tropical, it needs consistent warmth and humidity.
