The 6x4 Green Halls Supreme with Horticultural glass is an ideal greenhouse for a small space in your garden or allotment.
The attractive curved eaves on the Supreme are made from tough UV protected acrylic and give the greenhouse a unique look.
This Supreme 6 x 4 has a single opening roof vent for ventilation and a smooth single sliding door.

Our horticultural glass provides superior light transmission, durability, and UV protection, ensuring optimal growth conditions for your plants.

A solid base is the backbone of any greenhouse. You might think skipping this step saves time, but trust me?I've seen plenty of greenhouses fail because of poor foundations. A dodgy base causes more headaches than you'd believe.
What happens with a bad base? Glass cracks. Doors jam. The structure twists. Water pools where it shouldn't. And fixing these problems costs way more than doing it right first time.

The best position for a greenhouse in the UK is south-facing with the ridge running east to west. Keep at least 2 metres from buildings and trees, on level ground with good drainage. A south-facing 6x8 greenhouse runs 3-5 degrees C warmer than the same model facing north.
