Q: What kind of instructions do you give for assembling my greenhouse? 1. A DVD showing each stage of assembly. 2. A comprehensive assembly instruction manual with color pictures and 3. Written procedures for each stage of assembly. Ground preparation layout instructions included.

Q: What do I need for a foundation? We recommend setting the units on 4” x 6” timbers that are set into the ground. The top of these timbers should be visible above the ground. Remove the dirt from inside this frame and fill with crushed stone. This will pack down to provide a floor for the greenhouse. It will also allow for good drainage.

Q: Do I need a separate base frame? All units come complete. There are no additional frame parts required.

Q: I live in a very open area with high winds, can I secure the foundations without using cement footings? If the greenhouse is to be positioned in a highly exposed area, it is recommended that the timbers be pinned down using rebar (approx 1Ft from the corners). The holes need to be drilled at an angle of about 45 degrees toward the center of the timber with the rebar driven down below the top of the timber.

Q: What is the warranty on this greenhouse? The manufacturer gives 10 years on the polycarbonate against yellowing and 10 years on the aluminum frame. All additional electrics i.e. fans vents and the thermostat carry the standard manufactures warranty, normally 1 year.
