I grew some chillis from seed this year. The originals were red chillis
bought from a supermarket and were fearsomely hot to eat. They have now
grown into nice plants with plenty of baby chillis. I've tasted a couple but
they just don't have any 'heat' in them at all. They are bright red and look
fully ripe to me. A few years ago I grew some from seed and they turned out
just as hot as the originals. What has gone wrong this time??
