The purpose of this work is to describe and explain the process of installing a net house for transplanting watermelon seedlings in substrate, as well as to explain the agronomic management for the production of quality seeds. Producing seeds with coconut fiber (substrate) under net house conditions has several benefits with respect to planting directly in the soil: reduced labor costs, plant uniformity and better yields due to fertigation. Obtaining watermelon seeds under substrate conditions begins with the preparation of the module, that is, all the process that involves having optimal conditions inside the module for transplanting. In the production phase, once the female seedlings have been transplanted, pruning, thinning and pollination of the varieties will begin. Pollination involves cutting fresh male flowers and moving them to where the female buds are located, covering the bud stigma with pollen and waiting for the fruit to set, in order to obtain seeds with optimum genetic purity and adequate yields. Seed quality expresses the degree to which the established standards are met with respect to the following attributes: genetic, physical, physiological and sanitary. In order to produce seeds, constant care is required in all the processes to be carried out, from planting to harvesting, frequent training on work procedures for all personnel, supervision, and identification of critical points for each process. In addition, there is a quality control system as a second filter to supervise and reduce the risk of contamination. There are two types of contamination: self-pollination and presence of offtype fruit.
