Cold and showery again. Shed 8.1, 7.3, 2.1. Tunnel 17, 10, 1.5 @11:45
Interestingly it seems to get colder in the tunnel at night than up at the shed - possibly a height effect as the tunnel doors are quite leaky and the shed thermometer is 2m above ground sheltered under the protruding bit of roof, whereas tunnel one is 1m on a post and the doors are leaky so cold air probably flows through. I wonder if it would have been better to orientate the tunnel E-W, but that would be less good for morning and evening heat capture.
Heavy prolonged showers, so raked soil improver organic compost into tunnel beds and watered. Put weed mat around two more blueberries and weighted with gravel which seems better.
Overcast, feeling cold, rain started as soon as I arrived. 11.6, 6.2, 3.1. Tunnel 11,6,2 @10:45
No frost in last few days. Did some work on the tunnel beds then went home. Returned after lunch (and after the rain), still chilly but cleared ground for new cherry and dug a bit more around the pond. Fitted a square of weed mat around one blueberry and weighted down with turfs at edge, but not very good.
Light grey, air slightly damp so feeling colder, no wind
Quick temperature check: @15:15 outside shed max 8.9 current 7.1 min -2.4. in tunnel max 11.5 current 8.0 min -2.
(must have reset later on on Tuesday as when readings taken then the current was 16 in tunnel.)
Fine sunny and cold. Another heavy frost overnight. Beautiful crisp clear blue sky day, no wind.
Got on with mowing and raking up. Ground too hard for digging.
Temp check @ 13:45 outside shed max 7.1 current 7.1 min -1.1. in tunnel max 16 current 16 min -1
Dry sunny cold. Heavy frost. Underlane somewhat icy all day. Sun melted frost where it reached, but still white in afternoon on top strip shaded by hedge for about 20ft out, and also on north side of many tussocks. Only a flying visit.
Outside shed: max 5.8 current 5.8 minimum -5.8 @14:00, in tunnel 14deg @ 14:30, min -5.5deg.
Just a temperature check after two mornings of frost and a bright sunny day.
@14:30 max since Thurs 11.2, min -3.9, current 4.9 on digital
Second thermometer exactly the same - good.
Here briefly in rain to take photos of Grandie trees (to be done every 16th month this year)
Max/min since Sunday 13.2deg and 2.1deg. Temp @16:00 10.0deg
Second analogue mecury thermometer also installed above shed door for cross checking pending move to tunnel.
