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

Effective Tool
Color: Yellow, Size: 5.5" Lift
Go try to use your standard car jack to lift your two axle travel trailer and see why this simple ramp just works. I have used this ramp for changing trailer tires, packing bearings, and changing brakes. It's effective in lifting one tire even though the suspension is articulating. It is also much more stable than a hydraulic jack under an axle. I highly recommend this ramp for travel trailer use.

*Perfect* small camper hose for water filling
Size: 50-Foot, Style: Expandable Fabric
Well designed and very functional! Even if you have a small camper like a teardrop, I encourage you to get a longer length hose (minimally 50 ft). It really is drinking water quality hosing. I hate the weird plastic-y taste that you get from a standard yard hose. When I fill up the tank on my camper, I want water that tastes good, not like plastic--and this hose delivers. ZERO plastic flavoring! For pulling water from my house spigot, we can directly fill our water tank with zero issues. When we fill from well water or other sources on the road, we also add a water filter to the mix. I love that this comes with a mesh fabric holding bag to keep the hose stored safely and cleanly, while still allowing it to dry completely. The bag is large enough to actually accommodate the hose easily (although warning, it can be challenging to roll up this much hose without having the center fall out... pay attention when doing it, or better, do it on a flat surface before transferring it to the bag). I originally bought a 25 foot hose. That was a mistake. The 50 foot does not take up much more space in storage, but it is so much easier to work with when running from a spigot to your rig. I now have both a 25 ft and the 50 ft--and we bring both with us when on the road. There have been several times when we have needed all of the length of those two hoses connected. Sometimes you need to fill up at a gas station or rest area where it can be hard to either get your rig close enough, or when there are other vehicles blocking access. Having the extra length gives you options. The hose does not kink in use. At least, we have never had a problem with that happening. Mind you, we only roll it out straight to our camper, so it's not like I'm dragging it around the yard to water plants. Additionally, this is a remarkably lightweight hose, making it easy to move around. While not the cheapest, this is compact, easy to store, and it does its job perfectly, making it a very good value for the money.

Best RV water hose I've owned - flexible and durable
Size: 25-Foot, Style: Expandable Fabric
This Camco EvoFlex2 25-ft drinking water hose is outstanding and a huge upgrade from standard RV hoses. The flexibility is incredible—it stays supple even in cold weather and coils up easily without kinking or fighting you. No more wrestling with stiff hoses during setup and takedown. The drinking water safe certification gives me peace of mind that I'm not contaminating my fresh water system. No plastic taste or smell in the water like you get with cheaper hoses. The 25-foot length is perfect for most campsite hookups without excess hose laying around. The fittings are quality brass that don't leak and thread smoothly onto connections. They feel substantial and durable—no cheap plastic components that'll crack or strip. The hose itself is tough and resists abrasion from being dragged across gravel and pavement. After multiple camping trips, it still looks and performs like new. Easy to clean and maintain between uses. The flexibility means it stores compactly without taking up much space in the RV storage compartment. If you're tired of dealing with stiff, kinky RV water hoses, upgrade to this EvoFlex2. It's worth every penny for the convenience and quality. Highly recommend!

Great water hose. Easy and small to carry in motorhome bay. Don’t have the issue with trying to coil the hose up.
