An aquaponics, and greenhouse system comprising: an insulated solar greenhouse with a glazing on a sun facing side at an angle to maximize winter sunlight, and housing: a fish tank housed within the solar greenhouse ; a plant growing area housed within the solar greenhouse ; a mushroom growing area housed within the solar greenhouse ; a water wall thermal mass housed within the solar greenhouse and disposed between the plant growing area and mushroom growing area; and a natural air ventilation system housed within the solar greenhouse and configured to provide misted air into the mushroom growing area, wherein O2 generated by the plant growing area is received by the natural air ventilation system and provided to the mushroom growing area, and CO2 generated by the mushroom growing area is provided to the plant growing area; wherein the natural air ventilation system further comprises: a secondary roof plenum disposed underneath the roof of the greenhouse and coupled to a rain gutter water reservoir ; a water filter coupled to the rain gutter water reservoir and configured to filter water from the rain gutter water reservoir ; and a water pump coupled to the filter and configured to pump the filtered water to a mister spray head on an upper portion of the secondary roof plenum so that a water mist is sprayed and configured to condense within a channel formed by the roof of the greenhouse and the secondary roof plenum and return to the rain gutter water reservoir . a fish tank housed within the solar greenhouse ; a plant growing area housed within the solar greenhouse ; a mushroom growing area housed within the solar greenhouse ; a water wall thermal mass housed within the solar greenhouse and disposed between the plant growing area and mushroom growing area; and a natural air ventilation system housed within the solar greenhouse and configured to provide misted air into the mushroom growing area, wherein O2 generated by the plant growing area is received by the natural air ventilation system and provided to the mushroom growing area, and CO2 generated by the mushroom growing area is provided to the plant growing area; wherein the natural air ventilation system further comprises: a secondary roof plenum disposed underneath the roof of the greenhouse and coupled to a rain gutter water reservoir ; a water filter coupled to the rain gutter water reservoir and configured to filter water from the rain gutter water reservoir ; and a water pump coupled to the filter and configured to pump the filtered water to a mister spray head on an upper portion of the secondary roof plenum so that a water mist is sprayed and configured to condense within a channel formed by the roof of the greenhouse and the secondary roof plenum and return to the rain gutter water reservoir . a secondary roof plenum disposed underneath the roof of the greenhouse and coupled to a rain gutter water reservoir ; a water filter coupled to the rain gutter water reservoir and configured to filter water from the rain gutter water reservoir ; and a water pump coupled to the filter and configured to pump the filtered water to a mister spray head on an upper portion of the secondary roof plenum so that a water mist is sprayed and configured to condense within a channel formed by the roof of the greenhouse and the secondary roof plenum and return to the rain gutter water reservoir . <EOS>
