I always use a digital thermo/hygrometer (something like this one) with built-in memory so I can see what the maximum and minimum temperature was. It’s also a good idea to get one with a temperature sensor on a wire, so you can hang the display outside your grow room, and can see the temperature when the lights are off.
The thermo-hygrometer’s reading of the humidity in the concrete slab will tell you how much excess moisture is present deep in the slab that might evaporate up through the surface. This can tell you if the concrete is likely to damage the materials above it or suffer other problems.
Mar 09, 2017 · If you are wondering how to remedy these types of problems, you may need to invest in a humidifier in conjunction with using a hygrometer to read the comfort level of your home and then adjust the humidifier based on the readings the hygrometer is displaying. Hygrometers also make great additions to monitor the humidity for indoor plant care.

Thermometer definition is - an instrument for determining temperature; especially : one consisting of a glass bulb attached to a fine tube of glass with a numbered scale and containing a liquid (such as mercury or colored alcohol) that is sealed in and rises and falls with changes of temperature.
A thermo-hygrometer is necessary to control these parameters in our growing space. Plants must be watered according to their needs. Watering and fertilising marijuana. Marijuana seedlings need an abundant watering once they have been transplanted (½ litre per plant). A few days later, 150 ml of water per plant and day will be enough

A hygrometer is an instrument used to measure the amount of humidity and water vapour in the atmosphere, in soil, or in confined spaces. Humidity measurement instruments usually rely on measurements of some other quantity such as temperature, pressure, mass, a mechanical or electrical change in a substance as moisture is absorbed.
Set concrete cannot be easily penetrated by a pin meter, and it wouldn't allow for measuring in the core of the slab anyway. Therefore it’s often best to measure concrete with an thermo-hygrometer (RH meter). These devices.
The intensity of the returned lidar signal can be used to detect features buried under flat vegetated surfaces such as fields, especially when mapping using the infrared spectrum. The presence of these features affects plant growth and thus the amount of infrared light reflected back.
