Modular greenhouse

1. A foldable panel combination for a modular greenhouse, transitionable between a collapsed state and an assembled state, comprising:

a first side panel hingedly connected with a first roof panel at a first hinge;

a second side panel hingedly connected with a second roof panel at a second hinge;

a third hinge that hingedly connects the first roof panel to the second roof panel;

wherein the third hinge is disposed along an edge of the first roof panel and second roof panel;

wherein the first roof panel and the second roof panel each comprise a framework creating an open space enclosed by a cover;

a truss brace comprising a triangular framework having a first edge, a second edge, and a third edge that create an open space enclosed by a cover;

wherein, in the collapsed state, the first side panel, second side panel, first roof panel, and second roof panel are stacked and the truss brace is detached; and

wherein, in the assembled state, the first edge of the truss brace is attached to the first roof panel, the second edge of the truss brace is attached to the second roof panel, and the third edge of the truss brace extends between the first roof panel and the second roof panel.

2. The foldable panel combination of claim 1 , wherein the third hinge comprises a first hinge side movably connected with a second hinge side, and the first and second hinge sides each have an obtuse angle and an approximately 90 degree angle.

3. The foldable panel combination of claim 1 , wherein the first side panel and second side panel each comprise a framework creating an open space enclosed by a cover.

4. The foldable panel combination of claim 3 , wherein the cover of the first side panel, second side panel, first roof panel, second roof panel, and truss brace comprises a sheet made of plastic or polycarbonate.

5. The foldable panel combination of claim 4 , wherein the sheet is translucent.

6. The foldable panel combination of claim 4 , wherein the cover is attached to an outside surface of the framework.

7. The foldable panel combination of claim 3 , wherein the framework of the first side panel, second side panel, first roof panel, second roof panel, and truss brace is made of metal.

8. The foldable panel combination of claim 7 , wherein the framework comprises a tubing having a circular or rectangular cross-section.

9. The foldable panel combination of claim 1 , wherein the framework of the first and second roof panels have one or more holes for attaching the framework of the truss brace.

10. The foldable panel combination of claim 1 , wherein the framework of the first and second roof panels forms a rectangle or a square.

11. The foldable panel combination of claim 1 , further comprising a foldable roof dormer panel comprising four triangularly-shaped sections hingedly connected together and transitionable between a stacked collapsed state and an assembled state.

12. The foldable panel combination of claim 11 , wherein the foldable roof dormer panel is configured to attach to the first roof panel or second panel in the assembled state.

13. The foldable panel combination of claim 12 , wherein truss brace is configured to attach to the foldable roof dormer panel when the foldable roof dormer panel is in the assembled state.

14. A panel for a modular greenhouse comprising:

a tubing framework comprising a plurality of edges that form an open space; and

a cover sized and dimensioned to enclose the open space, wherein the cover is attached to an outside surface of each edge of the tubing framework via one or more fasteners.

15. The panel of claim 14 , wherein the tubing framework has a square or circular cross-section.

16. The panel of claim 14 , wherein the outside surface of each edge has one or more holes for receiving the one or more fasteners.

17. The panel of claim 14 , wherein the cover is a polycarbonate twin wall sheet.

18. The panel of claim 14 , wherein the cover includes a UV resin film.

19. The panel of claim 14 , wherein the plurality of edges of the tubing framework forms a rectangular, square, or triangular.

20. The panel of claim 14 , wherein the panel is hingedly connected with another panel.
