The need for the production of animal food for ruminants and poultry in an efficient way with less investment, higher yield, during the whole year and inside reduced environments, has taken us to practice different techniques like the production of green hydroponics forage (GHF). From the germination of the different seeds, being able to achieve some advantages in relation to the space, operability, health, and nutrition and cost reduction on animal feeding. Following the scheme of vertical cultivation, it is proposed through this work the resolution of the problems found during the GHF production, as they are: dependence of the seed, fluctuating prices of the seeds in the market and the cost of the workers due to the repetitive and constant daily shores, diminishing with this practice the animal feeding cost. The proposed work enables even more the reduction in the cost for animal feeding and facilitates us to perform annual or biannual sows to obtain harvests every fifteen days from the higher part of the forage and every month from the roots, taking advantage from both for animal feeding. Also, in this way we can avoid the daily handling of the plants during the production and optimise even more the space and use of water. The technique of the perennial forage using a light substrate, good seeds, programmed irrigation, specific cuts and balanced nutrition, allow the consumer to keep preserving the plant for long periods of time in an economical and adaptive way, avoiding the food variation for the animal and optimizing the permanence of the plant as a means to convert CO2 from the environment into carbohydrates that are useful for animal feeding. The used methodology is similar to the one used in the GHF production, with some differences in the substrate utilization and the irrigation with nutrients by aspersion. The comparative parameters, to be able to analyze the yield and the represented benefit are based upon, in some way, the parameters obtained for the GHF production, with the difference that the frequency on the irrigation and the cuts is every fifteen days. Just like the results obtained from the traditional cultivation of alfalfa, with the difference in the productive durability of the harvest.
