supported to help prevent property damage and injury in the event of strong winds or
inclement weather. Wind and ground conditions may vary from site to site, and may affect
the practicality and effectiveness of anchoring methods substantially. If you have any doubt
regarding the stability of the base/foundation you are to use, consult a professional.
Harbor Freight Tools cannot be held responsible for personal injury, damage to the greenhouse,
or other property damage that occurs as a result of improperly anchoring the greenhouse.
1. Excavate an area for the base of the greenhouse.
The area must be 10′ 2″ wide by 12′ 2″ long by
5″ deep. The floor of the hole must be level
and square. The diagonal dimensions, from
corner to corner, should each be 15′ 5″.
2. Assemble the Base outside the hole as shown
below. Note that the angled edges of the
Base Plates (43, 44) need to face the corners of
the base. Use Base Bolts (68), Base Nuts (69), and
Connectors (45, 46) to secure the pieces together.
3. With assistance, lower the Base into the hole.
The diagonal dimensions,
from outside corner to outside corner,
must be equal for the base to be square.
4. Fill the hole around the outside of the base with soil.
5. This base will need to be filled with about
40 cubic feet of gravel or another appropriate
fill material (not provided). The gravel should
When placing the Floor Plates (1a–6) on top of
the Base Plates (43, 44), align them as illustrated
above. The lip should extend slightly over the
edge of the Base Plate and the raised flange with
bolt holes should face inside the greenhouse.
2. Place the Front-Left Floor Plate (1a)
on top of the Base Plate (44). Lay the
Front-Right Floor Plate (2a) on top of it and line
up the 2 holes where the Plates overlap.
4. Place the Side Floor Plates (4) on the
Side Base Plates (43) on the front-right
and rear left corners as illustrated. Lay the
Upper Side Floor Plates (3) on top so that the
three holes line up where the Plates overlap.
5. Fasten the Side Floor Plates (3, 4) together,
and secure to the Base Plates (43) using
3 Hold-down Connectors (47) on each side
of the greenhouse in the places illustrated;
see illustration and inset on facing page.
6. Lay the Rear-right Floor Plate (6) on top of the
Rear-left Floor Plate (5) so that the 2 holes
line up where the Plates overlap. Fasten the
Rear Floor Plates (5, 6) together through those holes.
7. Place the assembled Rear Floor Plates (5, 6)
on top of the Base Plates (44).
8. Secure the Rear Floor Plates (5, 6)
to the Base Plates (44) using
2 Hold-down Connectors (47) in the locations
shown; see illustration and inset on facing page.
3. Fasten the Front Floor Plates (1a, 2a) together,
and secure to the Base Plate (44) using a
Hold-down Connector (47) over one of the
Bolts (65), see inset on facing page.
