Thanks for your help Pete, running at 37.4 give or take 0.2, since reading your thread I've been running dry as I have another 3 batches in, next one due on Monday, what does the daily cooling do, and will just opening up the incy to drop the temperature be sufficient? Also thanks for your comment re tilting the eggs upwards, been worrying about this but couldn't find any definate info and quite hard to get my eggs to stand up unless I rest them on each other, is that ok? Sorry for all the questions!
