🌱 What to Grow in February Without Grow Lights

You don’t need grow lights to start growing in February. In the UK, many crops germinate and grow perfectly well using natural daylight from windowsills, cold rooms, porches, or unheated greenhouses — as long as you choose the right plants.

The key is to focus on slow-growing, cool-tolerant crops that won’t stretch or weaken in low winter light.

🌿 Vegetables That Grow Well Without Grow Lights

These crops cope well with natural daylight in February.

🧅 Onions (from seed)

• Ideal temperature: 10–15°C
• Sow in trays or modules

Why they work:
Onions grow slowly and steadily, making them ideal for low-light conditions.

🥬 Leeks

• Sow thinly in trays
• Grow on indoors before planting out

Why they work:
Leeks dislike excessive heat and stay compact without artificial lighting.

🥬 Lettuce (hardy or cut-and-come-again types)

• Sow small batches regularly

Why they work:
Fast germination and compact growth suit windowsills well.

🌱 Spinach

• Sow in modules or trays
• Keep compost just moist

Why they work:
Prefers cool conditions and tolerates lower light levels.

🌿 Broad Beans

• Sow in deep pots or modules

Why they work:
Very hardy and unfazed by fluctuating temperatures and light.
