i almost forgot about the fruiting one
my friend had wrapped the bunch with a pair of track pants and put a hand warmer packet
hanging slightly below in the track pants so the heat would rise towards it
he did this on a couple nights when the temperatures went near zero (and there was frost)
the bunch has been cut now and is hanging
the yellow colour is likely cold damage and not ripeness
some seem filled in or close to it while others look angular still
hopefully we will be able to eat some!
