An improved hydroponic net pot includes a layer of filter material enabling moisture and nutrients to enter into the growth media, while preventing the growth media and debris from entering into the hydroponic vessel. The pot and the filter are both preferably constructed of biodegradable, compostable materials. The pot may include a non-zero shoulder allowing the pot to be inserted into vessels with vertical walls or upright, slanted walls of vertical vessels. A removable cover may be provided over the opening of the pot, enabling the article to be shipped with growth media, with or without seeds or plant material.
