A good start: warmth and light
Warm sowing can be done indoors or in a heated greenhouse. After germination, every seedling needs enough light. A dark attic needs grow lights. An unheated greenhouse can become very cold at night: measure the temperature and check the advice for your crop.

- Germination and temperature
- Germinate in cool, bright conditions; much lettuce germinates poorly above about 25 °C.
- 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.
Choose a spring, summer or winter cultivar. Celtuce has a different harvest aim from heading lettuce; follow its own cultivar window.
