Pre-growing is a commonly used method in horticulture, which consists of first planting the seeds in a controlled environment, such as a greenhouse or indoors, where they are protected from adverse weather conditions and allowed to grow in optimal temperature and humidity conditions. Once the plants reach a certain size or age, they are transplanted outdoors into a bed or outdoor environment. This technique allows gardeners to get a head start on the growing season, which is particularly useful in areas with a short growing season or for growing plants that require a longer time to reach maturity.
