“The indoor temperature remained stable overnight and in the early morning, with a slight drop to around 21°C near 03:00, but then rose quickly from 07:00, peaking at 26.7°C around 08:00. This peak is just within the acceptable upper limit for heat stress for the frost-sensitive crops. Despite full cloud cover during the day limiting solar radiation, relative humidity averaged high (71%), dropping to around 60% in the late afternoon during the highest temperatures but rising quickly in the evening and night to above 75% as temperatures fell. This creates a humid and cool climate, especially at night, which could increase the risk of fungal diseases like powdery mildew, while the daytime combination of warmth and humidity stayed within acceptable limits. Watch: check crops extra carefully in the coming days for early signs of powdery mildew or botrytis, especially in densely vegetated areas. Advice: consider manually increasing air circulation in the evening and night, if possible, to lower humidity somewhat, without causing too large a temperature drop.”
“The indoor temperature gradually rose from around 19°C in the early morning to 30.0°C around midday, a peak above 28°C that may have briefly caused heat stress in sensitive crops. Humidity dropped sharply during the day from 80% to 51% due to warming, and rose again in the evening to over 70%. Despite 100% cloud cover almost all day, the greenhouse became significantly warm, indicating that automatic ventilation was insufficient to fully keep the temperature within the comfort zone. For the rest of the day and night, temperature and humidity remained within acceptable margins. Watch: Consider manually increasing ventilation under similar weather conditions, as the automatic control did not fully keep the temperature below 28°C. Monitor humidity in the mornings over the coming days to prevent condensation and mold formation.”
“The indoor temperature fluctuated within a safe range, with a nighttime minimum of 14.8°C and a daytime maximum of 23.9°C. Low cloud cover during the night and early morning led to a slow temperature rise starting at 06:00. A peak of 23.9°C was reached only by 17:00, well below the heat stress threshold. Humidity was stable, with a fairly high value above 75% at night, but gradually decreased to 68% in the afternoon without unusual spikes. These stable conditions pose no direct risk to the crops, and the automatic control appears to be managing things well. Watch: keep an eye on the outside temperature in the coming hours, as high humidity of 70% combined with morning sun can lead to condensation on plants in the early morning, promoting mildew.”
“The indoor temperature followed a normal daily pattern, with a nighttime low of 14.7°C and a midday peak of 33.2°C. Humidity dropped sharply during the warmest hours to 38% but rose again at night to 84%. Cloud cover varied significantly, with notably less cloudiness (17%) around noon (12:00), explaining the temperature peak. Although automatic ventilation activated above 25°C, the temperature briefly reached 33.2°C, which may cause heat stress in sensitive crops. The combination of high temperature and low humidity midday increases dehydration risk, while high nighttime humidity raises the danger of mold. Advice: Consider manually adding extra water in the early morning to compensate for heat-induced dehydration. Watch: Check crops more closely for signs of powdery mildew due to the high nighttime humidity.”
“Yesterday, the greenhouse interior temperature followed a typical day-night cycle, with a nighttime low of 16.5°C and a daytime peak of 32.9°C, rising mainly in the morning and early afternoon. The warmest hours were around 10:00–12:00, with temperatures above 30°C, while humidity dropped to 43–58% due to the increasing heat. Later in the day, especially between 13:00 and 15:00, temperatures moderated due to variable cloud cover, but humidity remained relatively low. After sunset, humidity steadily rose to 82% as temperatures fell. Advice: For the coming day, consider deploying extra shade during expected clear periods to prevent a recurrence of brief heat stress peaks above 32°C, especially for sensitive crops. Watch: Check visually in the morning for early signs of powdery mildew after the humid night.”
“The indoor temperature showed a normal daily rhythm with a minimum of 17.7°C in the early morning and a peak of 29.2°C around noon. Despite nearly 100% cloudiness for most of the day, the temperature still rose to just above 28°C, which may cause light heat stress for sensitive crops such as strawberries, tomatoes, and bell peppers. The humidity dropped to a low of 48% during the day, which was beneficial for limiting fungal risk, but rose again to 82% at night, which could become a concern if nights get warmer in the future. The temperature curve was mostly well managed by the automatic window control, as shown by the post-peak decline. Watch: Check plants for signs of heat stress like leaf scorch, especially for bell peppers and strawberries. Consider additional manual ventilation in the morning if the temperature rises rapidly again under continued cloudiness.”
“The greenhouse temperature rose sharply in the morning from 17°C around 6:00 to a maximum of 31.3°C between 9:00 and 10:00, followed by a rapid drop to about 22°C around 13:00. This peak occurred during a period of clear weather (0% cloud cover) and exceeded the heat stress threshold of 26-28°C for strawberry, tomato, bell pepper, and chili. Humidity dropped to a minimum of 40% during these hot hours, which was beneficial for limiting mold risk, but the combination of heat and low humidity may have caused evaporation stress. In the afternoon, the temperature remained below 25°C, while humidity gradually increased to above 80% in the evening—a moist environment that increases the risk of powdery mildew, especially for frost-sensitive crops. Advice: Consider using temporary shade cloth tomorrow morning to flatten a rapid temperature rise in case of unexpected sunshine and prevent a repeat of heat stress. Watch: Check crops closely in the evening for early signs of powdery mildew, as humidity is high while temperatures remain relatively mild.”
“Yesterday was fully overcast with nearly 100% cloud cover until late evening, explaining the moderate temperature development. The indoor temperature rose slowly to a maximum of 27.6°C around 11:00, well below the heat stress threshold, followed by a notable and rapid drop to 19°C around 15:00. This sharp cooling, combined with humidity rising to 87%, created a brief risk of mold development for frost-sensitive crops, though temperatures recovered quickly. The night was cool but remained above critical frost limits. Advice: Check crops for early signs of mildew in the coming days, especially in the nearest sections. Watch: With persistent full cloud cover, low radiation may inhibit growth; consider monitoring plant load.”
“The inside temperature shows a normal day-night pattern, with a nighttime low of 18.7°C and a notable peak of 40.3°C between 12:00 and 14:00, which is far above the heat stress threshold of 26-28°C. The relative humidity dropped sharply during the day to 29% during the hottest hours and rose at night to 78%. Cloud cover was variable but reached 100% between 12:00 and 14:00, which was not enough to dampen the extreme heat. This indicates a period of severe heat stress for the crops (except grapes) and an increased risk of dehydration. Advice: Consider manually applying extra shade (e.g., with shade cloth) during peak hours to prevent a repeat of temperatures above 40°C. Watch: Check the crops for signs of heat damage, such as wilting or scorching.”
“Over the past 24 hours, the indoor temperature rose from 16.1°C at night to a very high peak of 40.9°C in the afternoon. Humidity dropped sharply during the day, from 76% in the early morning to a low of only 27% during the hottest hours. Despite varying cloud cover, the period around 14:00 with 0% cloudiness was clearly responsible for a sharp, direct temperature increase. The automatic window control appears to have functioned but was still not enough to fully moderate the extreme temperature peak, indicating significant heat stress for the crops. Although humidity was low, reducing mold risk, the combination of extreme heat and rising humidity later in the evening requires attention. Advice: Visually monitor sensitive crops like strawberries and bell peppers over the next day for signs of lasting heat damage, such as scorching or wilting. Consider a temporary additional cooling measure, such as a shade cloth, if a similar peak heat is expected.”
“The indoor temperature followed a normal daily pattern with a minimum of 13.2°C in the early morning and a maximum of 33.1°C in the afternoon. Despite automatic ventilation above 25°C, 33.1°C was still reached, indicating significant heat stress for sensitive crops like strawberries, tomatoes, and bell peppers. Humidity dropped sharply during the day to as low as 25% in the hottest hours, increasing the risk of desiccation, but rose again at night to 76%, which under cool conditions does not pose an immediate risk of fungal disease. Cloud cover was variable but provided insufficient protection from the high temperatures. Advice: Consider manually applying additional shade during peak hours to keep temperatures below 30°C. Watch: check the crops for signs of heat stress such as leaf scorch or wilting.”
