Generally, the old brick ash, fireclay ash and plant ash are not used as the nutrient soil, and the immature farmyard manure and simple chemical fertilizer are not used(3 gallon tree pots). During the seedling period, chemical fertilizer was applied, and the seedlings could be washed with water immediately to prevent the occurrence of dead seedlings(seed propagation trays). Generally, there is no topdressing at the seedling bed stage, and the solution to the lack of fertilizer mainly depends on the cultivation of bed soil.
(cheap plastic hydroponic trays for sale vietnam)As long as the bed soil is fertilized, the effective nutrients of the seedlings during the growth period after emergence should be selected(hydroponic farming tray).
