Which of the following practices can enhance greenhouse production?

Monitoring environmental conditions is crucial in enhancing greenhouse production because it allows growers to optimize the growing environment for plants. Key factors such as temperature, humidity, light levels, and CO2 concentration directly influence plant growth and development. By closely monitoring these conditions, growers can make necessary adjustments to ensure that the plants are thriving and are not subjected to stress that could hinder their growth or productivity.

For instance, if the temperature inside the greenhouse is too high, adjustments can be made such as increasing ventilation or shading to prevent heat stress. Likewise, monitoring humidity can prevent diseases related to excess moisture or provide appropriate conditions for flowering. Furthermore, understanding light conditions can help growers provide adequate supplemental lighting during short days or cloudy periods to maximize photosynthesis, which is essential for plant health.

In contrast, increasing plant density without considering environmental conditions can lead to competition for light, nutrients, and water, which may ultimately reduce yield. Ignoring pest signs may result in pest infestations that can decimate crops and lead to significant losses. Eliminating all external watering could deprive plants of necessary moisture, especially if the greenhouse's internal watering system is not sufficient to meet their needs. Thus, maintaining optimal environmental conditions stands out as the most beneficial practice for enhancing greenhouse production.
