Large 8x12 Greenhouse with Thermal Efficiency and Superior Airflow

6mm Twin-Wall Polycarbonate for Year-Round Temperature Control

This 8x12ft greenhouse is fitted with 6mm premium twin-wall polycarbonate panels. The insulated glazing diffuses harsh light, retains warmth during colder months, and reduces heat gain in summer — all while protecting plants from UV damage on both sides.

Extra Ventilation and Durable Frame for Harsh Conditions

With four roof vents included, this model provides excellent natural airflow to prevent overheating and regulate humidity. The rust-resistant aluminium frame is powder-coated in matte black for long-lasting strength and sleek aesthetics.

Designed in New Zealand. Assembled in Australia.

Manufactured in New Zealand and assembled locally, this glasshouse is purpose-built for Australian conditions. Unlike many imported kits designed for milder climates, Winter Gardenz structures are engineered to handle the extreme weather seen in regional and coastal Australia — from strong winds to temperature swings.

Spacious Interior for Dedicated Growers

At 2596mm wide x 3844mm long, this 8x12 model offers plenty of space for raised beds, multiple staging levels, and propagation setups. It’s a great choice for home growers who want serious output with the control and protection of an insulated structure.

  • Dimensions: 2596mm (W) x 3844mm (L) x 2615mm (H to ridge)
  • Height to gutter: 1620mm
  • Glazing: 6mm twin-wall polycarbonate (UV-protected both sides)

Nice bed
Color: Blue, Size: Large (Pack of 1)
Good quality dog bed. My pittie loves to burrow himself under blankets so I figured we would give this a try. He hasn’t figured it out yet but it’s his new favorite spot to take a nap when he’s not on our lap. Love the color and seems to be nicely made. I do wish it came in a bigger size but it’s still big enough for him.

Nice quality bed

Nice quality. My dog loves laying on this bed but hasn’t yet figured out getting inside. I cover him after he lays and he seems to enjoy it

Cozy Bed, Just Needs Fluffing
Color: Blue, Size: Large (Pack of 1)
Our dog took to this bed pretty quickly and seems to like curling up under the cave cover. It’s soft, roomy, and gives that little tucked-in feeling a lot of pets seem to love. The cover doesn’t always stay perfectly shaped, so I have to fluff it back up now and then. Other than that, it looks nice in the corner and seems comfortable enough for daily naps. Solid bed overall, especially for the price.

NOT WATERPROOF OR MACHINE WASHABLE
Color: Blue, Size: Large (Pack of 1)
Until today, I would have given this bed 5 stars. When I was looking for a new pet bed, I searched for “waterproof” and “machine washable”. My bad for not verifying those attributes before purchasing as I have learned Amazon search results are not reliable. Today one of my dogs peed on the floor and dragged his bed over it. When I discovered it, I wasn’t concerned because it is waterproof and machine washable. Uh, no it is not. The cushion was wet and was too big to adequately fit in my washer and I could tell the fabric wouldn’t hold up so I hand washed in the tub. But by this evening it was still pretty wet so I tossed it in the dryer on low - by itself - to get the damp out. Well, when I took it out, the cushion had ripped open. Meanwhile, I put the cover in the washing machine. It washed okay, but the plastic part that helps the the opening stay open came out and broke. I cannot find a hole to attempt to put it back in. I am really irritated that it isn’t better made.
