    Greenhouse Thermometer Recommendations and Location in the Greenhouse.

    Greenhouse Thermometer Recommendations and Location in the Greenhouse.

    Have purchased 2 Greenhouse Thermometers over the last 2 years a digital one, parts of the LCD failed within a year and a old fashioned analogue type which is not very accurate (different readings between the max min sides) I am considering a dial type like these any comments.

    or

    Also where in the greenhouse do you put yours?

    Dunno about others, but I don't find simple Max/Min enough info. Knowing that the temperature fell to X doesn't tell me how long it was cold, how much the heater fluctuated (the nearer to target temperature it maintains / the less "overrun" there is, the cheaper it is to run)

    So I use a sensor that transmits the temperature to the house / my PC and records it continuously. I can then look at a graph

    I can also check what temperature the greenhouse is, this time of year, and decide when to trot over there to open it up / close it in the afternoon.

    If the greenhouse is too far from the house / on an allotment, then there are logging thermometers which allow the data to be downloaded (plug into USB / similar).

      Same as Kristen.

      I use kit made by Corintech. It's not cheap though.

      Here's what happened in the greenhouse last night:

        BBC Click had an episode on electronic gardening monitoring gadgets (and things like robotic insects which could pollinate plants in the future). "Click" is all a bit off-stage-left for me ... but perhaps some things of interest.

        BBC News Channel - Click, 04/04/2015

        Parrot Flower Power sensor (push it in the ground) measures:

        "Capacitive sensor for soil humidity
        Conductive sensor for the fertiliser content of the soil
        Light sensor (which can also act as a warning light)
        Soil and air temperature sensor        "

        transmits to your phone by Bluetooth when you are nearby.

        £50 (£35.50 each for 2+)

        Also Koubachi garden sensor which looks more robust / sophisticated (says MIN operating temperature 0C though which would be worrying ...)

        £94
