Frequently Asked Questions

Can I build a Monticello Greenhouse on a concrete slab?

Yes. A concrete pad can be used as the base, but it should extend 3–4 inches beyond each side for stability. For example, the 8×8 model (8.1×8.1 ft actual) would use a slab up to 8.4×8.4 ft.

  • Purchase concrete anchors separately (not included in the kit).

What tools are included, and what will I need to provide?

Included:

  • Spacer (23 1/8 inch)
  • 7/16 wrench
  • Philips screwdriver
  • Flathead screwdriver
  • 5-foot bungee cord

Required (not included):

  • Work gloves
  • Safety goggles
  • Bubble level
  • Measuring tape
  • Step ladder
  • Silicone sealant caulk

Can I expand my Monticello Greenhouse in the future?

Yes. All Monticello models are compatible with extension kits:

Are Monticello greenhouses hurricane-proof or earthquake-proof?

No formal hurricane or seismic testing has been done, but they are strong when assembled correctly. Inspect bolts periodically, especially after high winds or seismic activity.

What’s the difference between automatic vent openers and ventilation fans?

Automatic vent openers use temperature-sensitive mechanisms to open/close roof vents without electricity. Ventilation fans are powered and move more air, but will not cool like an AC unit.

Do the doors swing or slide? What are the door dimensions?

The doors are hinged and swing outward. The door opening is 4 ft wide × 6 ft high.

Where are Monticello greenhouses shipped from?

All Monticello greenhouses ship from Georgia, USA.

What materials are used for the frame and panels?

The frame is anodized aluminum, and the panels are UV-protected polycarbonate.

  • Black frames are finished with electrostatic paint for added durability.

Is the black frame powder-coated?

No. Black frames use electrostatic coating, which is more durable than powder coating.

Does frame color affect temperature?

Yes. The aluminum frame is approximately 7°F cooler than the black frame in sunlight.

What is the warranty?

Riverstone Industries provides a 10-year warranty on both the aluminum frame and the polycarbonate panels.
