Lidl thermometer

[cptncrackoff]

Hi all, I checked my max min lidl thermo earlier, it tells me that it was 33c in my greenhouse today, in my mind that is beyond all realms of fantasy... it was 7c ish outside... could it really have been 33c in my greenhouse!?
Ive no other thermometers to test it against.
Surely it wasnt that warm in there?

[veggiechicken]

Just checked mine its 3.3C outside Was yours in direct sunlight?

[cptncrackoff]

...yes..., i'm going outside to check it now, when i got home 4pm it said 7c which i thought was more realistic, do I need to hide it under something in the greenhouse to get a more accurate reading, will the sun heat up the black plastic and send it haywire?

[out in the cold]

It was 28C in my classroom this afternoon, so yes it is possible

[veggiechicken]

You need to keep it in the shade, or at an angle to the sun. Maybe under a bench?

[cptncrackoff]

Its 3.0c inside, 2.0c outside, and definatly too cold to be outside in just pants and a headtorch.
I did squash a slug though that was heading for my onions!
This might explain why my broad beans I have in there are flowering.
I shall hide the thermometer under a shelf, reset and see what tomorrow brings.
It didnt seem that sunny here today, im very suprised at the reading, all the other readings seem feasable although the outdoor max shows 11.9c which I dont think it was.

It was well into the twenties in my conservatory s'afternoon. Soon heats up with the sun on the glass......

[veggiechicken]

That sounds more accurate cptn - mine's 3.1 outside the kitchen window now.

As others have said, keep it out of direct sunlight Cptn or you will get false readings.

There was frost on the ground here yesterday just before mid-day and the temperature in my greenhouse was 97.2 ºf. or 36 ºC. My hi-lo thermometer is shaded. The heat builds up alarmingly quickly in the spring sunshine. I have bubblewrap lining my greenhouse and I use fleece to shade my plants.

[WendyC]

Yes I've had temperatures in the 30s from very little sun and quite cold outside.

[alldigging]

Yes perfectly possible. Ours was high 20s yesterday. Can check it on our max thing but only if its been reset since last weeks 33'c

The autovent on my g/house opens at about 24C and even in hazy sunshine is often open

a chilli growing friend of mine had 36 degrees in the GH on tuesday in Galloway, Scotland where they seem to be hogging the Spring sunshine at the moment
