Product Information

Full details

The Dunster House Growzilla 8x12ft Greenhouse is an ideal choice for dedicated gardening enthusiasts looking for a durable, all-season structure to cultivate everything from delicate seedlings to seasonal vegetables. Its primary advantage is the combination of pressure-treated timber and high-clarity toughened glass, which provides both long-term structural integrity and optimal light transmission for plant health; however, prospective owners should note that its substantial size and weight require a permanent, level foundation and significant assembly time.

FAQs

Does the greenhouse come with a floor?

The Growzilla is typically designed to sit directly on a prepared level foundation; it does not include an integral floor.

Can I install shelves inside the Growzilla?

Yes, the sturdy timber frame allows for the easy installation of wall-mounted shelving or the placement of freestanding staging units.

How often should I treat the timber?

While the wood is pressure-treated, we recommend applying a high-quality water-repellent wood preservative every 1-2 years to maintain the finish.

Is the toughened glass safe?

Yes, 4mm toughened glass is designed to break into small, blunt fragments rather than large, sharp shards, making it safer for garden environments.

Can I assemble this by myself?

Due to the size, weight of the materials, and the nature of handling glass panels, we strongly recommend a minimum of two people for assembly.

Troubleshooting

Door is sticking or not closing properly

Check if the base has shifted. Use a spirit level to ensure the frame is square and adjust the foundation if necessary.

Roof vents failing to open

Verify that the automatic opener mechanism is not obstructed by debris and ensure the temperature setting is calibrated correctly.

Drafts inside the greenhouse

Check that all glass panes are properly seated in their seals and that the frame joints remain tight; apply greenhouse-grade sealant if gaps are found.

Pros and Cons

Pros

  • Superior durability due to pressure-treated timber construction
  • 4mm toughened glass ensures both safety and high light transmission
  • Automatic roof vent system simplifies climate management
  • Spacious 8x12ft design accommodates a wide variety of plant types
  • Provides a controlled environment to extend the growing season

Cons

  • Requires a solid, level foundation for proper installation
  • Assembly is time-intensive and recommended for two or more people
  • Significant space requirement in the garden
  • Requires periodic maintenance of the timber frame

Setup, Compatibility & Care

Proper setup is critical for the longevity of your Growzilla. Always install the greenhouse on a perfectly level base, such as a concrete pad or a pressure-treated timber perimeter, to ensure the frame remains square and the doors function correctly. Because the structure is heavy, enlist help for the assembly phase to handle glass panes safely. For care, inspect the timber annually for any areas that may require a fresh coat of wood preservative. Clean the glass twice a year using mild soapy water to remove algae or dirt buildup, which ensures that your plants receive the maximum amount of natural light possible throughout the changing seasons.
