The climates within the walls of poly houses, glasshouses and hoop houses are no less dynamic than the ones that bring rain, sun, wind, clouds and snow to the outside world. But the inside has one tremendous advantage: growers can control the climate with a wide variety of methods.

This report surveyed more than 100 growers to find out where they’re growing, what they’re growing and the methods and challenges of controlling the most micro of microclimates within their operations. They reported a constant concern with heat and puzzling over the ability to ensure a variety of plants grow optimally under the same roof.

Survey methodology: In April 2025 we surveyed greenhouse managers whose primary business is growing ornamental or edible crops for either wholesale or retail operations. The base for questions ranges between 107 and 125 participants. Answers were collected in May.

Editor’s note: Not all percentages add up to 100% due to rounding, non-responses and some questions allowing respondents to select multiple answers.
