The **Jetma F1** white cabbage is a high-performing, ultra-early hybrid variety known for its very short growing cycle of 45 to 60 days from transplanting, making it ideal for early cultivation in greenhouses or under plastic covers. It produces attractive, light green, round heads typically weighing between **0.8 and 1.5 kilograms**, which is the perfect size for home consumption and fresh market sales. This variety is highly regarded for its mild, pleasant flavor—excellent for fresh salads—as well as its consistent, high-yield production that ensures uniform maturity for efficient harvesting.
