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

Fun dog toy
Size: Medium(6")
Great ball, easy to use, sturdy toy, and fun toy that dogs love. Only a 4 star as I wish it was a little bit bigger and with more handles.

Nice ball w/straps to grab for ur dog to carry the ball.
Size: Medium(6")
She’s afraid of SO many things. Gotta give her more time. From a hoarding group…so, no socializing. Time will tell. Very nice ball w/ tough straps to grab hold of & carry it.

These are NOT meant for regular play like the other reviews seem to think.
First things first, ignore 90% of these reviews. The reviews saying these balls didn’t last very long clearly don’t know what they’re meant for. These are not “drop and play” kinds of toys. They’re meant to be used as reward toys. Meaning they get used during training sessions for a quick game of tug to reward the dog for good behavior. These are NOT meant for unsupervised play, and not meant for dogs who don’t have reliable recall or drop/Aus commands. That being said, my dog is 95 pounds and stands 29” at the shoulder. She’s a big girl who plays rough. Immediately after opening the package, we did a quick training session with these reward toys. They held up EXTREMELY well. They are made of rubber which means she doesn’t shred them in one short game of tug unlike some of the foam reward toys you will come across. I did have to tighten the knot below the ball before using them, but that’s to be expected with any rope style toy. If your dog does not have a reliable drop command and they are any larger than maybe 25lbs, I would not suggest using the smaller ball. If Nikita didn’t have a reliable drop command, it would be incredibly easy for her to wind up choking on the smaller ball. Even the large ball is pushing it on choking hazard size for a large dog, but again, reliable drop commands are important.
