Greenhouse Thermometers Buyer’s Guide
The best greenhouse thermometers have a clear easy to read display so you can see the temperature at a glance. Many digital thermometers have a backlit display which makes the thermometer easy to read in low light, too.
The best greenhouse thermometer will show the current temperature as well as the minimum and maximum temperatures recorded. This is extremely handy in the greenhouse as you can easily see what the highest and lowest temperature were throughout the day and night. This function is easily reset at the touch of a button. Many digital thermometers will also measure humidity and display this clearly on the screen. Again, many will also show the minimum and maximum humidity which are useful figures for the gardener to know.
Most digital thermometers are accurate to +- 1 degree which is usually precise enough for most gardening needs.
Your digital greenhouse thermometer will last longer if it is weatherproof even if used in a greenhouse. Greenhouses are often damp and humid, and your thermometer may be subjected to condensation, drips and spray.
Many thermometers come with a warranty for added peace of mind.
Where is the best place to position a thermometer in a greenhouse?
You should avoid placing your thermometer in direct sun as this will give readings that do not reflect the overall temperature. You can shade the top of the thermometer with foil to help prevent this. In general, it’s best to place the thermometer about mid-height and away from doors, windows and heat sources. Remember that the temperature will be a little higher above the thermometer and a little lower below it.
Of course, if you have specific plants you want to protect, then place the thermometer near these to check the temperature in that specific area.
A greenhouse thermometer is an essential tool for the gardening enthusiast as it allows you to create the perfect conditions for your plants. Tender plants can easily wilt in too much heat and die if they are damaged by frost. A greenhouse thermometer will help you regulate the temperature in your greenhouse and provide your plants with the perfect growing environment.
I recommend the OutdoorHome Digital MIN/MAX Thermometer as it is accurate, attractive and weather-resistant and displays the current and minimum and maximum temperatures on a clear display.
