What Holds Heat Inside a Greenhouse?

How does a greenhouse stay warm inside?

A greenhouse stays warm inside, even during the winter. In the daytime, sunlight shines into the greenhouse and warms the plants and air inside. The transparent materials of a greenhouse, be it glass or polycarbonate, allow sunlight to enter but trap the heat inside, preventing it from escaping. This ensures a consistent warm temperature, perfect for plant growth.

What material traps heat in a greenhouse?

A greenhouse stays warm inside, even during the winter. In the daytime, sunlight shines into the greenhouse, warming the plants and air inside. Gases in the atmosphere trap heat like the glass roof of a greenhouse. These heat-trapping gases are called greenhouse gases.

Essential Elements for a Warmer Greenhouse

  • Thermal Mass or Heat Sink: Creating a thermal mass or heat sink is one of the easiest and least expensive options for warming greenhouses in the winter. These objects absorb heat during the day and release it during the chilly nighttime hours, raising the temperature by a degree or two.

  • Greenhouse Insulation: Greenhouse insulation is crucial for maintaining warmth. Greenhouse plastic sheeting is an excellent material for insulation. You can buy it online or at your local store to use on your greenhouse.

  • Heating Options: Heating a greenhouse with gas is the most cost-effective choice. Electric heaters, gas heaters, and wood-burning stoves are other accessible options that help maintain a constant temperature. Grow lights can provide the necessary light for plant growth during the winter months.

  • Functionality of Greenhouses: A greenhouse is a transparent structure that offers plants a superior growing environment compared to outdoors. Supplemental lighting and heating are sometimes added to counteract short daylight hours and cold temperatures. Greenhouses come in various sizes, from commercial acres to small home hoop houses.

Greenhouse Heating Mechanism

A greenhouse works by converting light energy into heat. Light enters the greenhouse and is trapped there by the glass and absorbed by the plants and other objects. This causes the light energy to be converted to heat energy, which is trapped inside the greenhouse. This provides the ideal environment for plants to thrive year-round.
