Professional greenhouse manufacturers , cost-saving and convenient to use, is a kind of equipment for cultivation or breeding that is constructed simply. The greenhouse has great space-efficient performance and strong ventilation ability, also preventing the heat loss and the intrusion of cold air.

PREPARING FOR THE COLD: HOW TO WINTERIZE A GREENHOUSE

With the winter months fast approaching, every grower knows that now is the time to prepare their greenhouses for the onslaught of winter weather and cold temperatures. It is important for growers to winterize their greenhouse, so their grow can thrive even during the coldest winter months.

Winterization mainly consists of preventative measures to ensure a smooth transition into the colder months for an operation, so it is advised that growers begin this process in the fall. Starting winterization when temperatures have already gotten colder, or worse yet, not winterizing at all, can have detrimental effects on a grow.

Preparation is essential for a grow to flourish during the winter. Many steps can be taken to prepare a greenhouse for the winter, including cleaning the greenhouse from top to bottom, testing systems’ functionality and ensuring a greenhouse is properly heated and insulated. These are all vital aspects of an operation that need to be properly tested and prepared well before winter begins and temperatures start to drop. By doing this, growers will ensure their operation can combat the winter and keep their grow thriving.

1. Insulate the Greenhouse: Proper insulation is key to reducing heat loss. Insulate the walls, roof, and foundation using materials like bubble wrap, polyethylene film, or polycarbonate panels. Install them on the inside of the greenhouse structure, covering the entire surface area.

2. Seal Air Leaks: Identify and seal any air leaks to prevent cold drafts and heat loss. Check for gaps, cracks, or openings around doors, windows, vents, and any other potential entry points for air. Use weatherstripping, caulking, or foam sealants to seal these areas and create a tight seal.

3. Install Thermal Screens or Curtains: Thermal screens or curtains provide an additional layer of insulation. Close them during the night or during colder periods to trap heat within the greenhouse. These can be automated to open and close based on temperature thresholds.

4. Insulate the Flooring: Insulate the greenhouse flooring to prevent heat loss from the ground. This can be done by adding a layer of insulation material, such as foam boards or polystyrene, beneath the flooring.

5. Maintain Adequate Ventilation: Although insulation is crucial, proper ventilation is still necessary to prevent excessive humidity and condensation. Ensure that vents and exhaust fans are functioning correctly and keep them clear of debris. Use ventilation systems or vents with adjustable openings to regulate airflow.

6. Check Heating Systems: Inspect and maintain your greenhouse heating systems. Clean or replace air filters, check for any issues with burners or heating elements, and ensure proper operation. Consider scheduling a professional inspection or servicing if needed.

7. Utilize Thermal Mass: Incorporate thermal mass, such as water barrels or rock beds, into the greenhouse. These materials absorb and store heat during the day, releasing it at night to help maintain a stable temperature.

8. Monitor and Control: Install a greenhouse environmental controller to monitor and control temperature, humidity, and ventilation. Set temperature thresholds and ensure the controller is functioning properly. Regularly check and calibrate sensors to maintain accurate readings.

9. Protect Plants: Move sensitive plants closer to the center of the greenhouse, away from the cold walls and windows. Use additional insulation, such as row covers or frost blankets, to protect plants from extreme temperatures. Consider using plant heating mats or greenhouse-specific heaters to provide localized warmth.

10. Prepare for Snow and Ice: Clear snow accumulation from the greenhouse roof to prevent excess weight and potential damage. Install snow guards or barriers to prevent large amounts of snow from sliding off the roof. Remove ice from walkways and ensure they are safe for access.

11. Monitor Weather Conditions: Stay informed about upcoming weather conditions and adjust greenhouse preparations accordingly. Be prepared to take additional measures, such as adding extra insulation or heating, during severe cold spells.

Remember to customize your winterization efforts based on the specific needs of your greenhouse, the types of plants you’re growing, and the local climate conditions. Regularly monitor and adjust the greenhouse environment as needed to ensure the best possible winter growing conditions.
