I can't add much more than I wrote before, as I don't put probes into pots, 
I merely record highs/lows over 24 hour periods.  Over the last week or so 
I have recorded minus three on two nights and minus four on one - external 
temperatures were down to minus seven for five or six hours on one night, 
with winds of 10-15 mph (I live on a hill and the greenhouse is reasonably 
exposed.  The greenhouse itself is a 10m long structure, with metre high 
benching.  As I said before, most of the bulbs I grow in it are in one 
litre pots, which sit on the plunge.  Composts are soil based, with added 
grit.  There are a mixture of summer, winter and evergreen bulbs, nearly 
all in it are from South Africa and South America.  Many of them do sit in 
areas that have a second covering of horticultural fleece, but many are in 
the open on metal staging.

I do not water at all during cold periods, but try to give them a good 
soaking as soon as a mild period arises.  Its starting to warm up again 
tomorrow, so it will be watering day.

Hope that helps.

Best regards,
David Victor
