Artificial Lighting, Soil Warming Cable and Watering System
The artificial lights that the onions have been growing under for sixteen hours every day, right from the day they popped their heads through the compost, will now be reduced to 12 hours until planting out time. Last year they were planted on the 27th of March straight from my greenhouse into the polytunnel soil. I must however make it quite clear that I was only able to do this because the soil had already been warmed up using a soil warming cable.
