Get a handle on exactly what's happening in your greenhouse with our Thermometer & Hygrometer - designed to give your seedlings and young plants the very best chance of being the biggest and best croppers on the allotment or in the kitchen garden this year.

Measuring 11cm tall by 7cm wide, the unit will record and display the current temperature within a huge -5ºC (+23ºF) to 50ºC (+122ºF) range to a 1ºC accuracy, along with the relative humidity between 30% and 90% - essential for healthy germination and to help prevent conditions that diseases like botrytis just love. You can also check what's been going on in the greenhouse whilst you've been away or asleep as well thanks to the max/min function, available in both temperature and humidity modes. A complete pocket-sized greenhouse information centre!
