By retaining light and heat greenhouses are designed to provide the ideal conditions for plants to grow. However, if the greenhouse is not properly ventilated, the air becomes stagnant and humid which can create an unsafe environment, allowing fungi to grow. Good ventilation is also important for preventing the greenhouse from becoming too hot which will kill plants.
When the temperature becomes a little cooler, there may be the need to use a heater in the greenhouse, especially at night. Be sure to use a heater specifically intended for greenhouses so that you prevent it from becoming a fire hazard. You also want to have this in mind when using other electrical items in there. Make sure they are suitable for outdoor use and when you are not using them, keep them unplugged and stored in a safe place.
You may discover the occasional leak in your greenhouse. To prevent too much moisture accumulation, mold or other hazardous pathogens from developing, try to fix any leaks as soon as you find them. This will also help keep away insects.
Keep a lock on your greenhouse. This is especially important if there are small children in the household. A greenhouse often contains gardening tools, pesticides or other items that would be dangerous if young children got their hands on them.
These simple suggestions will help to ensure your greenhouse is a safe and pleasant environment for all.
