I’m told that for chilli seeds, happiness is a warm environment. I had reasonable germination results last year but not many of the chilli plants made it to the point they could be transferred into the polytunnel. I had used a heating system to keep them at about 20°C. This year, having studied a bit more, I’m using a smaller propagator but boosting it to 25°C for the germination phase to try and give them a very positive start. I’m interested to see if that is enough to keep the seedlings – and me – happy with their progress.
