  2. Polytunnel - Wikipedia

    en.wikipedia.org/wiki/Polytunnel

    In a tropical climate, temperatures are prone to soar above all normal levels. In such cases, foggers/misters are used to reduce the temperature. This does not increase the humidity levels in the poly house as the evaporated droplets are almost immediately ventilated to open air.

  3. Soil moisture sensor - Wikipedia

    en.wikipedia.org/wiki/Soil_moisture_sensor

    A simple soil moisture sensor for gardeners. Soil moisture sensors measure the volumetric water content in soil. [1] Since the direct gravimetric measurement of free soil moisture requires removing, drying, and weighing of a sample, soil moisture sensors measure the volumetric water content indirectly by using some other property of the soil, such as electrical resistance, dielectric constant ...

  4. Pan evaporation - Wikipedia

    en.wikipedia.org/wiki/Pan_evaporation

    Pan evaporation is a measurement that combines or integrates the effects of several climate elements: temperature, humidity, rain fall, drought dispersion, solar radiation, and wind. Evaporation is greatest on hot, windy, dry, sunny days; and is greatly reduced when clouds block the sun and when air is cool, calm, and humid. [ 1 ]

    Currently, the greenhouse industry is the largest component of the CEA industry but another quickly growing segment is the vertical farming industry. Controlled Environment Agriculture has the ability to produce crops all year round, with the possibility of increased yield by adjusting the amount of carbon and nutrients the plants receive.

  6. Greenhouse - Wikipedia

    en.wikipedia.org/wiki/Greenhouse

    A greenhouse is a structure that is designed to regulate the temperature and humidity of the environment inside. There are different types of greenhouses, but they all have large areas covered with transparent materials that let sunlight pass and block it as heat.

  7. Meteorological instrumentation - Wikipedia

    en.wikipedia.org/wiki/Meteorological_instrumentation

    The measurements taken include temperature, barometric pressure, humidity, wind speed, wind direction, and precipitation amounts. Wind measurements are taken as free of other obstructions as possible, while temperature and humidity measurements are kept free from direct solar radiation, or insolation. Manual observations are taken at least once ...
