June–July for many autumn typesSow thinly in modules and follow the specific cultivar period.
- Germination and temperature
- Allow even germination; avoid cold stress during early propagation.
- After emergence
- Keep emerged lettuce bright and well ventilated; prevent high greenhouse temperatures and drying out.
- Pricking out and potting on
- Sow in modules or prick out manageable seedlings into individual cells. Keep the root ball intact when planting out.
- Hardening off and planting out
- Gradually acclimatise indoor-raised plants to sun, wind and outdoor temperatures; shelter them again on cold nights. Plant out sturdy young plants; keep the growing point clear and protect against slugs and snails.
These types have different cultivar windows. Early cold can encourage bolting; summer sowing is the usual route for many autumn types.

Guideline periods for the Netherlands and Flanders. Check the variety, available light, soil and measured temperatures. Greenhouse heating does not guarantee enough winter light.
