This disclosure describes a positive pressure greenhouse including one or more plants disposed on a plant table surface, wherein the plant table surface is disposed above ground level and has an area below the plant table surface and above the ground, one or more upper wall tubes including one or more upper wall tube fans disposed above the plant table surface, one or more lower sidewall tubes comprising one or more lower side wall tube fans disposed below the plant table surface which may be at or near ground level. The one or more lower sidewall tube fans may be configured to draw air from the area below the plant table surface, wherein air is further drawn down from above the plant surface table, e.g., the area of the upper wall tubes and upper wall tube fans, to ground level of the greenhouse. The one or more lower wall tube fans may also be configured to blow air into the area below the plant table surface wherein the blown air further rises above the plants and into the area of the upper wall tubes and upper wall tube fans.

This application is directed to greenhouse structures, including greenhouse structures with managed airflow.
There are often problems with tunnel ventilated and cross flow ventilated buildings for example greenhouse structures. Both create negative pressure using fans at one wall pulling air out of the building and having cool pads with water flow at the opposing wall allowing outside air into the building and cooling it via evaporation of water at the cool pad. One must condition all the air volume of these types of cooling buildings. Air also takes the least path of resistance so air quality in the building may be spotty due to high air flow in some areas and low air flow in others. When a door is opened, air rushes into the vacuum and the conditioning of the building may stop functioning.
A positive pressure building forces air into the building at strategic points and with the use of interior circulating fans and maintains proper air flow at the lower strata. The ridge of the building is open so cooled air comes in at the lower strata of the building perimeter, and hot air naturally rises out the ridge.

Throughout the drawings and the detailed description, the same reference numerals refer to the same elements. The drawings may not be to scale, and the relative size, proportions, and depiction of elements in the drawings may be exaggerated for clarity, illustration, and convenience.
The following detailed description is provided to assist the reader in gaining a comprehensive understanding of the methods, products, and/or systems, described herein. However, various changes, modifications, and equivalents of the methods, products, and/or systems described herein will be apparent to an ordinary skilled artisan.
The present disclosure provides a greenhouse configured to force air into the building using fans (blowing air into the building) causing it to have positive pressure. This pressure blows air out any holes which insects may use to enter the building. The incoming air may also be filtered using an insect screen with openings too small for thrips (very small insects). If pollen is a problem, a specialized filter is installed to collect any pollen from the incoming air flow. Air access chambers are used to enter the building. An air access chamber has an exterior door and an interior door. Open the exterior door, enter the chamber, close the exterior door, open the interior door and walk/drive in.
