How many crops we can grow in a polyhouse
The number of crops you can grow in a polyhouse (also known as a greenhouse or high tunnel) in a year depends on several factors, including the type of crops you choose, the duration of each crop's growth cycle, and the local climate conditions. Here are some considerations that can help you determine the number of crops you can take in a polyhouse in a year:
-
Crop Selection: Some crops have shorter growth cycles and are better suited for polyhouse cultivation. Leafy greens, herbs, and certain fast-growing vegetables like radishes and baby carrots are ideal for multiple planting cycles.
-
Growth Cycle: The growth cycle of each crop, from planting to harvesting, varies. Some crops may take a few weeks (30-60 days), while others may take several months to mature.
-
Succession Planting: With careful planning, you can practice succession planting. As you harvest one crop, you can replant the same area with a new crop, extending the growing season and maximizing yield.
-
Local Climate: The local climate and temperature variations can influence the number of crops you can grow. In colder regions, polyhouses may provide more controlled and extended growing seasons.
-
Climatic Conditions Inside Polyhouse: The use of polyhouses allows you to create a more favorable microclimate, enabling you to grow crops even during suboptimal weather conditions.
-
Crop Overlapping: Some crops can be grown simultaneously if they have similar growth requirements. For example, you could have fast-growing leafy greens like lettuce or spinach growing alongside longer-maturing tomatoes or peppers.
-
Crop Rotation and Soil Health: To maintain soil health and prevent pests and diseases, you may need to rotate crops. This can impact the number of crops you can grow in a year.
-
Maintenance and Preparation Time: Keep in mind the time required for preparing the polyhouse, sowing seeds, transplanting, maintaining crops, and cleaning between growing cycles.
As a rough estimate, you could potentially grow three to five cycles of fast-maturing crops like lettuce, spinach, radishes, and herbs in a polyhouse throughout the year. For longer-maturing crops like tomatoes, peppers, and cucumbers, you might have one to two cycles, depending on your location and climate.
