A useful DIY way to heat up the greenhouse! You just need two terracotta pots, a large nut, bolt and washers, a couple of bricks and a nightlight candle. Watch the video on YouTube to find out how (skip the ads!). Remember, this is for the greenhouse only and be careful not to have fleece or anything flammable near it.
The video suggests using small nightlights, but they don’t last through the night – better to use 8-10 hour nightlights.
Have any CABAHS members tried this? Does it work?
