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)

Pump stops working
I love this primer and color however the last 2 bottles I have gotten the pump stops working with the container still at least half full. I have to take the entire top off to get to the primer.

Soothes dry, eczema prone skin
Size: 1 Fl Oz (Pack of 1)
My son has moderate eczema and it seems to really flare up when his skin is dry. We started to use this as a final step in his bath time routine and I’ve noticed a pretty big difference in his skin. I usually wash him off with soap, then put this on to sink in for the remainder of his bath and rinse off right at the end. When I don’t use it I notice his skin is drier and more itchy. It is a staple in our bath time routine!

Gentle and works well
Size: 1 Fl Oz (Pack of 1)
We really like this! It’s gentle on my daughter’s skin and hasn’t caused any irritation. It lathers nicely without being harsh and leaves her skin feeling clean and soft. A great option if you’re dealing with sensitive or eczema-prone skin.

AMAZING so far!!!
Size: 1 Fl Oz (Pack of 1), Size: 1 Fl Oz (Pack of 1)
So far so good! Bought this out of desperation my poor bub was suffering with red itchy eczema so bad and bathing her resulted in painful stinging and screaming. Last night I used this cream wash in a lukewarm bath about 96 degrees and quickly and gently wash her entire body no more than 10 minute bath since we have extremely hard water…I then SMOTHERED her in baby advanced therapy aquaphor before putting her onesie on and the next morning her skin looked so much better. The ingredients aren’t totally great and is why I hesitated to purchase at first but it ended up being fine. Very creamy and moisturizing, does not have suds at all which is what eczema needs. No smell to it which is good cause she’s very sensitive to fragrance. Big bottle for the price. I would recommend giving it a try, every baby is different but if you’re desperate like I was it can’t hurt to give it a shot. I have attached a before and after picture of her belly, first was before the bath and second is the morning after.
