Last week I put a max/min thermometer in the greenhouse. On Saturday the temperature peaked at an impressive 29°C, pretty good for November! This has been beneficial for the long-chilies as one of them has now started to turn red.
On Sunday I went round filling the gaps between the base and the ground with concrete and also ran silicon sealant round the edges of the greenhouse frame. This should keep the draughts (and rain) out.
This coming weekend I’m hope to start work on the heatsink.
