10 x 20 ft Greenhouse for Serious Growers Who Need Space and Thermal Efficiency

6mm Twin-Wall Polycarbonate for Insulation and Plant Protection

This 10x20ft greenhouse features 6mm twin-wall polycarbonate glazing that offers excellent thermal performance, shielding plants from frost and harsh sun. The diffused light promotes healthy growth while maintaining a more stable internal environment across all seasons.

Expansive Layout and High Roof for Efficient Workflow

With internal dimensions of 3220mm wide and 6386mm long, the structure provides ample space for propagation, plant staging, raised beds, and walkways. The tall 2850mm roofline improves airflow while allowing room for trellised crops or vertical shelving.

Designed in New Zealand. Assembled in Australia.

Manufactured in New Zealand and assembled locally, this greenhouse 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.

Award-Winning Design and Rust-Proof Frame

The frame is built from powder-coated matte-black aluminium, offering exceptional durability and corrosion resistance. Combined with a streamlined modular design, it’s easy to assemble and built to last.

  • Dimensions: 3220mm (W) x 6386mm (L) x 2850mm (H to ridge)
  • Height to gutter: 1620mm
  • Glazing: 6mm twin-wall polycarbonate (UV-protected both sides)
  • Frame: Matt-black powder-coated aluminium
  • Wind Rating: Up to 150km/h when installed to specification

Oil pan has been great. Used it on my 2015 2500 for oil and rear diff changes. No problems at all.

Holds it all and easy to use!
Style: 16 Quart Drain Pan
I bought this oil drain pan when preparing to teach myself how to change my own oil on my Toyota Tundra 1794. Yes. Youtube and I…we be mates. Anyway! This drain pan easily held all of the old nasty oil and made it easy to complete a dirty job in a relatively clean way!

Good
Style: 16 Quart Drain Pan
I have had no issues with leaking. Just double check the o rings are good and in place and you shouldn't either. Although I'll be honest it's pretty over priced. You can go to home depot or o Reilly and find the same exact thing for a third of the price. All the same it's holding my oil just fine.

Not so good - oil splashes all over !!!
Style: 16 Quart Drain Pan
I am SO glad I just saw this pop up in my "purchased" items category...I am not only a Do it yourselfer but I also perform service work for a group of clients as well and I have to say I had a version of this before and threw it out after many years of service due to the fact it started dripping/leaking and I did not want to waste time trying to find it! with that said I purchased this and "What a mistake" every time I change the oil if it does not hit exactly the right angle or area the oil just ricochets off the surface and splashes all over the garage surface (especially when working with 0w20 type oil - thin)...I think this one will be seeing the can soon as well even after only 30-40 uses!!
