The best place to set up a greenhouse depends on several factors, such as the climate and environment of the area. Generally speaking, an ideal location should have plenty of sunlight, good air circulation, protection from strong winds and pests, and easy access to water. A south-facing slope is usually preferable for maximum sun exposure. Additionally, consider nearby sources of heat in winter months that can help maintain a warm temperature inside the greenhouse. Finally, ensure there is enough space around it for ease of maintenance and harvesting of your organic produce.
