Are grow lights worth it in the UK?
Yes grow lights UK are worth it. They make it possible to grow herbs, salad leaves, and even fruiting plants indoors all year round. With short winter days and cloudy weather, grow lights give consistent results that natural light alone can’t match.
How many hours of light do plants need?
Most seedlings and leafy greens need 14–16 hours of light per day. Fruiting crops such as tomatoes and peppers usually do well with 12–14 hours. Use a plug-in or smart timer to keep schedules consistent.
Can I use normal bulbs instead of grow lights?
Standard household bulbs don’t provide the full spectrum or intensity that plants need. Purpose-built LED grow lights are much more effective and efficient, giving healthier, stronger growth.
Do LED grow lights get hot?
LED grow lights run cooler than older HID lamps, but high-power LEDs still generate some heat. Keep airflow moving around your plants and adjust the light height if leaves show signs of stress.
What are the best indoor grow lights UK gardeners use?
LED panels and bar-style lights are now the most popular options in the UK. They deliver strong light output with low running costs.
