February

• Clean glazing panels to maximize light transmission.
• Prune dead or diseased plant material.
• Plan for early spring planting.

March

• Start seeds indoors for spring planting.
• Check irrigation systems for leaks and clogs.
• Ensure proper ventilation as temperatures begin to rise.

April

• Transition seedlings to the greenhouse.
• Inspect and clean ventilation systems.
• Begin fertilizing plants as they enter the growth phase.

May

• Install shade cloths to prevent overheating.
• Increase watering frequency as temperatures rise.
• Monitor for pests and diseases.

June

• Maintain consistent ventilation and cooling.
• Harvest early crops and start succession planting.
• Clean and disinfect tools and equipment.

July

• Check and adjust misting systems to maintain humidity.
• Ensure all fans and vents are working efficiently.
• Remove any dead or decaying plant material.

August

• Continue monitoring and maintaining cooling systems.
• Start planning for fall planting.
• Inspect structural elements for wear and tear.

September

• Begin reducing watering as temperatures drop.
• Remove shade cloths to increase light exposure.
• Clean and store summer-specific tools and equipment.

October

• Prepare heating systems for the upcoming winter.
• Begin planting cool-season crops.
• Insulate the greenhouse to retain heat.

November

• Check and repair any damage from fall storms.
• Monitor temperature fluctuations and adjust heating.
• Mulch around plants to retain moisture and warmth.

December

• Perform a thorough cleaning of the greenhouse.
• Review and plan next year’s planting schedule.
• Ensure all systems are functioning for winter conditions.

Preparing for Winter

• Insulation: Add bubble wrap or thermal screens to glazing panels to retain heat.
• Heating Systems: Test and service heaters to ensure they are ready for cold weather.
• Plant Protection: Group plants together to create microclimates and use thermal mass (e.g., water barrels) to store and release heat. Cover sensitive plants with frost cloths.

Summer Cooling Strategies

• Shade Cloths: Install shade cloths to reduce sunlight intensity and lower temperatures.
• Ventilation: Maximize ventilation by opening vents and doors during the hottest part of the day. Use exhaust fans and circulation fans to enhance airflow.
• Evaporative Cooling: Consider using evaporative coolers or misting systems to lower the temperature and increase humidity.

Troubleshooting Common Issues

Condensation Build-Up

Solution: Improve ventilation by opening vents and using fans to increase air circulation. Consider using a dehumidifier if necessary.

Uneven Temperature Distribution

Solution: Use fans to distribute heat evenly. Consider adding thermal mass, like water barrels, to store and release heat.

Yellowing Leaves

Solution: Check for nutrient deficiencies and adjust fertilization accordingly. Ensure proper watering practices to avoid overwatering or underwatering.

Poor Light Levels

Solution: Clean glazing panels to maximize light transmission. Supplement with grow lights during low-light periods.
