Before sowing

Soak

18 h Soak seeds in warm water (about 30°C) for 12-24 hours before sowing

Warm water soaking accelerates germination; no other pre-treatments required

Sowing

Substrate

well-draining, nutrient-rich soil; can use seed-starting mix

Depth

superficie

Temperature

25°C

Moisture

alta

Container

small pots or modular trays for indoor sowing; 5-8 liter containers for growing

Day/night swing

Temperature drop overnight aids germination; alternating temperatures can improve germination

What to expect

Step 1

Pre-treat the seed

Step 2

Sow at superficie · 25°C

Day 3–14

Seedlings emerge (~80%)

Tips

Requires full sun (at least 6 hours daily); warm-season crop that needs soil temperatures above 18°C (65°F) for outdoor sowing; keep soil moist but not waterlogged during germination; sensitive to drought after imbibition begins; seeds require light to germinate and should be surface sown without burial; does not require scarification or cold stratification; adapt better to light conditions during germination
