Why we love it

Easy assembly with click-together frame.

Durable cover for superior protection.

Separate doors for convenient access.
Main highlights

OTHER GROW TUNNEL SIZES AVAILABLE: The grow tunnel greenhouse is also available in other sizes to suit your garden, allotment, or patio space. Choose from a 2 section grow tunnel (L130cm x W60cm x H50cm) or 4 section grow tunnel (L260cm x W60cm x H50cm) to expand your growing space. Other sizes subject to availability and may not be in stock.
INDIVIDUAL DOOR ON EACH SECTION: Whereas most grow tunnels have a single roll-up door, our grow tunnels have a door on each individual section (3 doors in total). This allows you to open one section at a time when tending to your plants or vegetables. Ties allow you to fasten the doors open to regulate the temperature and encourage pollination.
HEAVY-DUTY MESH COVER: The cover has been designed by sandwiching a mesh grid between two layers of thick polyethylene. It’s thicker and stronger than a PVC cover for superior durability, stability, and insulation. Because the mesh rid is coloured white, it blocks out less sunlight than a cover with a green mesh to promote stronger, healthier growth.
CLICK-TOGETHER FRAME FOR EASY ASSEMBLY: No tools are required to build the growhouse. Its frame consists of steel poles and plastic connectors which seamlessly slot together. Simply place the cover over the top, tie it to the frame, and secure the peg points to a lawn or bed using the pegs included. The poles are powder-coated for rust-resistance.
3 SECTION GROW TUNNEL (1.95M LONG): Give fruit and veg the very best protection with this Grow Tunnel Greenhouse from Christow. The grow tunnel has 3 sections to grow different crops and measures L195cm x W60cm x H50cm when erected. It’s an excellent way to protect crops from pests, birds, and the elements when growing in your garden.

VOUNOT
VOUNOT Polytunnel Greenhouse 4x3x2m 12m² Poly Tunnels Gardening Walk In Pollytunnel Tent with Steel Frame

8.4 Easy to build

7.4 worth the money

7.0 Durability

Why we love it

Durable and UV-protected cover.

Easy to assemble and disassemble.

Enhanced ventilation with windows.
Main highlights

REINFORCED, HIGH PROTECTION, ANTI-UV protective cover - The tarpaulin is UV-treated and water-repellent. It is made of high-density polyethylene (140 g/m2), which provides strong UV resistance but leaves behind the sun rays necessary for growth
Quality manufacturing - Our garden greenhouse is made from 19 mm steel pipes. Steel has a galvanized finish to protect against corrosion.
EASY AND SUPPORTIVE ASSEMBLY - Our greenhouse is easy to assemble or disassemble. The tarp is ready for use and has an additional floor that can be buried to better withstand the wind
DIMENSIONS: 400CM L x 300CM W x 200CM H. Enjoy an area of 12m² to grow your plantation.
CAUTION: As with all greenhouses on the market, it is recommended to dig trenches and bury the metal base to prevent the greenhouse from blowing away. IT IS NOT ENOUGH TO PLACE IT ON THE GROUND. Our greenhouse has better wind resistance thanks to the excess tarp for burying, but this does not mean that the greenhouse can withstand medium and strong winds. It is therefore highly recommended to remove the cover when there is wind.
1 ROLLER DOOR AND 8 SIDE WINDOWS WITH MOUSTIQUAIRE - The roller door gives you easy access. The 8 side windows with mosquito nets cool the air circulation in your greenhouse
