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)
  • Frame: Matt-black powder-coated aluminium
  • Roof vents: 4 included for improved ventilation

Not a chew toy.
Color: Black & Lake Blue
The inside it a hard plastic, my dog can’t chew it. Plastic on the outside is very durable, my dog likes the noise it makes and will chase it but loses interest fast. I will not buy again.

Intense healing in a convenient jar!
Size: 13.5 Ounce (Pack of 1)
A great healing lotion for all over body application. I like the product being in a jar so there is no problem getting the lotion out of a bottle making this a very wise economical choice. A 72 hour intense healing lotion providing a long lasting healing experience. Highly recommended.

The texture is rich but still absorbs nicely into the skin, and a little goes a long way. I NIVEAs

deep hydration and works especially well for very dry skin. The formula feels rich and nourishing but still absorbs nicely without feeling greasy. After applying it, my skin feels soft, smooth, and comfortable for hours. I also love that it contains ingredients like glycerin, Pro-vitamin B5, and niacinamide to help repair and protect dry skin.
