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

8oz Size Perfect for Small Amounts of Milk
Size: 6.8oz/200ml Silver
This is a quality pitcher with a nice weight to it. I only use 80ml of milk in my cappuccinos and had trouble getting a good microfoam when using a larger pitcher. This little 8oz pitcher is the perfect size and makes it easier to achieve microfoam. The only potential issue I see is the pitcher may overflow if using more than 80ml although this may be due to my technique.

Pretty and functional
Size: 6.8oz/200ml Matte Black
I really liked the size and functionality of this milk pitcher, it’s really elegant looking as well. I use it for when I want to make an iced coffee that I need to mix stuff with and it holds a good amount of coffee. Easy to clean and pour as well, for what I paid I think it’s worth it.
