Assembly
Read the ENTIRE IMPORTANT SAFETY INFORMATION section at the beginning of this document
including all text under subheadings therein before set up or use of this product.
IMPORTANT–READ THE FOLLOWING CAREFULLY BEFORE PROCEEDING
• The first step in assembly is to assemble a proper base. The greenhouse must be properly
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.
• It is always your responsibility to ensure that the greenhouse is properly anchored.
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.
• Be certain to check with local authorities to obtain all required building permits
and to familiarize yourself with any building codes that may apply.
• Decide on a location for the greenhouse. The location should optimally be a
level, well-lit area that is sheltered from the wind. The door of the greenhouse
should not open towards the prevailing wind, if possible.
IMPORTANT ASSEMBLY TIPS
• Assemble Bolts with their heads facing the outside of the greenhouse, unless stated otherwise.
Tighten Nuts (67) only about 1/4 turn past finger-tight; be careful not to overtighten.
• Lay out all parts by number prior to assembly.
• At least two assistants will be necessary during assembly.
• Assemble on a clear, calm day. Wind will damage the Greenhouse and make assembly difficult.

Base Assembly Instructions
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 on
facing page. Note that the angled edges of the
Base Plates (43, 44) need to face the corners of
the base. Use Normal Bolts (65), Nuts (67), 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
reach up to about 1″ below the lip of the base.
