q: Are these greenhouses very wind resistant?
a: They aren't designed for high wind areas, but they're pretty sturdy. Our best suggestion would be to install in as sheltered a spot as possible and read the reviews on this and other sizes to see how others have a got on and where they installed.

q: How do you fix it to the ground? Does it have pegs and or guide ropes as quite windy where I live.
a: It doesn't come with fixings as there are lots of ways to do it, depending on where it is going. You can use pegs, steel warratahs (see the 3m x 6m customer photos), bent rebar or similar if it's going directly onto the ground. Some people build wooden boxing and attach over the top using brackets and wood screws etc. Take a look at some of our customer photos on the different models for ideas, or give our sales team a call on 0800 800 880.

This is the 2nd of this Tunnel House I have purchased, which alone says it all. What a terrific product. If I have one criticism is that the doorways are difficult to roll up by oneself, apart from that I love them.

Very easy to assemble, plastic cover very thin and will not last long in harsh weather. But for the price this is a good overall product.

I brought one for my school and once I put it up purchased one for my family to use at home. The structure seems good. Built it on a raised bed and strapped it down. Hopefully, the cover lasts well. Time will tell.

This is a great product especially for the price. Well made and easy to assemble. Put it up in a day. Have put a wooden frame around the bottom (which acts as a raised bed) that I have attached the frame to, to make it doubly secure and sturdy.

Easy to erect with great temperature control without letting in unwanted pests by controlled use of the windows on both sides.

Good Value

about 1 year ago


Good value for money, possible for one person to erect by themselves. Although putting on the cover would have been easier with an extra person. Very easy to put together, the directions enclosed were easy to follow. Nice to see doors at opposite ends, although would appreciate one of them to have the zip in the middle as I require two beds with walking space up the middle. Would be happy to recommend and will be purchasing another in the future.

I put it up by myself but I would not recommend that, I would suggest that you get help on site but managed it anyway, once I had it up I looked at how I was going to fix it to the ground and after a beer I decided that I wanted my Tunnel House to be higher and secured to a frame,to do this I would have to raise the height so that the plastic was off the ground and I then built a 8m x 3m wooden frame with 8 x 100mm x 100mm x 1000mm posts buried the posts 300mm and attached a base to the outside of the posts with 300x 30mm boards, once I had them in position I lifted the tunnel house over the frame and rested the bottom piping on the edge of the timber board then pulled the plastic tight and screwed the pipe into the edge of the board, simple as and it meant that my Tunnel house had the roof at 2300 high which is great and solid with it, inside it gave me 700 mm of my square posts to attach a bench that was 400 mm wide and 8 m long which I can do on both sides, As I am going into Hydroponics and using the bench space for dutch buckets its turned out really good and it also leaves me a 2200 mm width of space inside which is fantastic, I am certainly going to be expanding my Hydroponics so I'll definitely be buying more of these infact the next one I will be growing Tomatoes so i think i will lift that with two boards wide giving me 600 protection for the base and also giving me 2600 height inside, These grow tunnels are such great value, we had big winds through after it was finished and it was solid as,thanks to you trade tested for selling these, I have sent 3 people your way so far as they have seen what I have done and also seen the quality of the Tunnel House and the price is amazing. I will be back very soon to get more for our expansion, Trade Tested rocks !!!!

Solid product for the price

about 1 year ago


I purchased this over a month ago and go it setup on the first weekend after receiving it. It took a few of us a good 5 hours to fully put it together to a good standard but was very happy with how it turned out. It seems to be a good quality build for the price tag, so happy even if it lasts 2-3 years. But I imagine with some good care it would last longer. So far it has kept my subtropical and tropical trees well and truly alive so far. Requires some manual work to open and close ventilation but that's part of the price tag :) I'd recommend this to anyone that wants a greenhouse and is on a budget. It's a great starting point. I secured mine to the ground using wooden pegs and "U" type brackets around the pipe, screwed to the wooden peg. Trade Tested were also good to deal with and delivered it in a prompt way. Highly recommended all around.

Great Tunnel House

over 2 years ago


Arrived quickly, it was easy to put up - especially with two people. I recommend reading all the reviews and questions on every size available to get every tip and hint most of which we used. My zucchini and tomatoes are well away in Autumn! PS one philips head screw was included with allen heads which was a bit of a surprise lol

Large Tunnel House

This greenhouse is great. Easy to construct. Good size. We have put it over the existing outside garden to give the vegetable garden protection from the birds and rabbits etc. Love how each end opens up with the zipped flaps and also the roll up windows for air movement.
