Cheers Nick, It might have dropped to about 8-9oc at night over the last few days. Today has been pretty sunny and a lot of the chillies have started to turn red now. i'll move them away from the window at night and put them back during the day and hope for the best.
My outside chillies have been a disaster. I put 3 plants outside in one of those little plastic greenhouses, but left the flap open all the time, so they didnt get too hot.
There are quite a few chillies on them, i'd say about 30-40 between the 3 plants, but they all have wierd marks on them. Like little abrasions. One of them had started rotting and half the stem it was on was also going soft. I think i'll just bin them all as I have more than enough on my indoor plants.
Same has happened with all my tomatoes, they were perfect when inside and as soon as I moved the plants outside they are covered in abrasions and marks. Might be due to the constant bombardment of rain we have been getting here tho.
If I grow some next year i'm just going to go for 1 type of each plant. Hopefully i'll be able to overwinter this Naga and one of my Cayenne plants then maybe buy a scotch bonnet and jalepeno plug next year. Then fill the rest of the window up with a few Bell peppers.
