Anyone tried a USB thermometer? they capture and record temps constatntly. only £20. data can be transferred to excel to make graphs etc.

its a bit too scientific for the average grower - data not really needed for basic growing.

a digital one is your best bet, same price and will record the max/min temps of grow room.

I prefer my trusty wireless thermo/hygrometer...saves me running about constantly checking

Any recommendations on a wireless one with min/max ??
Also whats the range on the wireless?

and..er...how much?

there. I think that's enough annoying questions.....

just google WH1170 or wireless weather station
