timing of CO 2 enrichment should be considered, as the increased air exchange rate during periods of active ventilation, either for temperature or humidity control, minimizes its efficacy. Supplemental lighting, temperature control, and CO 2 enrichment

Abstract
A freezer system is described for subjecting biological materials to temperatures between +50° and -85°C. The system provides for removal of latent heat of fusion, adjustment of tissue water content, uniformity of temperature, control of supercooling and a wide range of cooling rates.
Abstract
A soil cooling system was developed using a chest-type freezer as a central cold air reservoir. Thermostatically controlled fans circulate cold air from the freezer into smaller air chambers containing large plastic pots. The system is inexpensive, easily constructed, and provides good soil temperature control.
Abstract
Turnip (Brassica rapa L.) growth in an unshaded, temperature-controlled greenhouse varied annually as a function of month. Growth was proportional to the average daily irradiance at plant level, but variance of the data suggested an interaction with some other environmental factor, possibly reduced substrate and plant temperature due to reradiation to the cold greenhouse glass at night during winter.
