Seems to be a problem with this one - panels come loose and the door came off. Product might be ok in a sheltered area but no good when exposed to strong winds. Would recommend spending a bit more and getting something more robust.

I agree with comments on the difficulty of assembly, very poor instructions and quality of the fixings. I don't live in an area noted for its windy conditions but a couple of weeks ago the wind destroyed the opening vent by ripping it off and blew out five panels. I have bought some extra clips and hope they will suffice. My advice would be - 'Don't buy one of these'.

Instructions to build this greenhouse are poor to say the least. It was hard to work out if the parts were to face in or out from the diagrams. The vent slides on to the roof bar and this was not explained fully on the instructions. The bars also do not fit snuggly and with a gust of wind would not hold shut with the catch. Until I come up with a better idea i have secured this with some wire. The quality of the nuts and bolts is inadequate and cheap - many twisted and sheared so have spares! I bought new, good quality ones to replace them. The plastic stopper for the bottom of the door snapped when screwed in so I now need to get a replacement part. The sliders for the glass were difficult to push on and this task was very time consuming. That said, everything does appear sturdy (except for the roof vent) and it does look nice but a very frustrating building process. Lets hope for some good summer crops.

Insructions not easy to follow the aluminium bolts are of the poorest quaulity and snap when under windy conditions my greenhouse collapsed in a gale despite my own sturdy anchors which are still in position poor product and poor anchoring system supplyed by the manufacturers, cheap and nasty.

I bought the 6 x 4 version. I agree with others about susceptibility to wind damage. I have placed it near fence and shed and hope it will survive - but suspect it is liable to damage.

Construction is a bind. Worse than IKEA. Lots of fiddly bits. Plastic nuts and bolts are a disappointment - beware using power tools to tighten. I think the manufacturers could have included at least another 20% quantity to make up.

Some of the diagrams in the instructions are very hard to follow. Lack of clarity as to what is the inside or out. Don't rush it - remember the saying 'measure twice, cut once'. Double read before commitment.

The door didn't fit properly and still doesn't despite many attempts to get it right. It isn't wind or rain proof.

Some parts of the construction are out of sync and if you follow will lead to correction once you try to put together. That's life.

The stainless spring clips to fix the glazing are a mystery. Not sure how they are supposed to work as the diagram in the instructions is as much use as a chocolate ashtray. I have tried to find a clearer instruction on the web.

When finished it looks like what it is - a cheap, flat packed plastic greenhouse which from a distance looks like it is practical. The polycarbonate glazing is about as tough as corrugated cardboard - don't expect it to stand up to all the weather can throw at it! But then again that's what you bought so cannot complain but not hopeful of it surviving the winter.

At first thought the Gardman 8x6 PC greenhouse a good buy, after two weeks think it a poor buy. Instructions very poor ,my son and I are both technically minded and DIY able but struggled to complete in two days. but it looked nice
Today I spent some hours recovering PC panels from various gardens despite the greenhouse being in a very sheltered position. I dread the thought of a REAL gale arriving.
I am now researching methods of making it a usable unit. I suspect it will involve considerable expense and time (and frustration!)
I would not recommend this to my enemies, much less friends.
When you ring them they say they do not have complaints - take that with a bucket of salt - just read the reviews.
Having read the reviews maybe trading standards should look into it!!!!

The Gardman 8x6 Polycarbonate Greenhouse was OK while installing the PC panels, however, on a very light breezy day it was noticed how quick they are to BOW when the wind hits them. So we added extra bracing internally to the general frame work and roofing area. Then we used a strip of 2"x4" wooden batten, one strip down the inside of each side midway between top and bottom of the largest panels and bolted through to the frame at each frame point. This effectively limited the BOW from the wind and had the bonus of strengthening the framework overall. Same was done with roof panels,.
Result, one polycarbonate greenhouse that doesn't get me out of bed worrying on windy nights.
Extra costs 10 £ in total.

Frame looks very flimsy but fingers crossed, my Gardman 8x6 Polycarbonate Greenhouse will last a few years. I brought the greenhouse before reading any reviews. I wouldn't have if i did. However I brought 200 extra glazing clips on ebay and drilled the uprights and ran 2 rows of wire around the sides and roof. We have had some strong winds and everything is still in place. I bought an autovent from homebase for around £17.00 (own brand) and it works fine.

I don't think that I would buy this Greenhouse again. 2 days to assemble and now I have lost window panels due to strong winds. I am trying to find out where i can order more polycarbonate panels.

Got the 8'x6' version in September with plans to have it in place for the spring. All pieces arrived safely in three cardboard boxes (base, frame, glazing).
Built it over two weekends by myself. There were a couple of stages during building the 8'x6' frame where an extra pair of hands would have been useful to keep things steady.
Putting in the glazing panels was slow due to having to line the seems with rubber edging. Getting the glazing panels attached with the 'W' clips got easier with time but expect your thumbs to be fairly raw after pushing in so many of them.
I put in a floor of gravel to aid drainage and put paving slabs up the middle as a path.

A few weeks after building it one of the side panels blew out when it was windy. Managed to put it back on but was concerned about how easily it had popped out. So I bought an extra 100 wire 'W' clips from ebay to reinforce the glazing panels.

A month after that one of the panels on the front of the greenhouse, beside the door, blew out. Fortunately it was a Saturday morning and the noise of it woke me up and I managed to get it reattached before it blew away.

Please note that the polycarbonate panels are really light and if the wind catches them they will fly a long distance.

Decided I needed to come up with another solution for keeping the glazing panels in place because every time it got windy you could see the panels straining, trying to escape.

The solution I came up with was to install retaining wires on the outside of the greenhouse. I bought a long length of 1.5mm steel wire and some fixings.
I'll describe what I did for one of the sides of the greenhouse.
I drilled 2mm holes in the green frame uprights, near the top of the uprights and very tight to the glazing panels. Then I fed the wire through the holes so that it went from the front of the greenhouse to the back. Then I used clamp fixings to lock the wire in place at each end.
I repeated the above procedure twice more for that side of the greenhouse, with one wire near the bottom of the uprights and one wire around the middle.
The end result was three retaining wires running from front to back to try to stop the glazing panels from blowing out.

I had done this procedure on about half of my greenhouse when we had a really big storm. The first thing that happened was the door blew off and once the wind got in it blew out all the greenhouse panels that did not have my retaining wire.
The panels that escaped flew everywhere and I've lost two of them and some that I found are cracked from smashing into things. So I'm going to have to buy some replacement glazing panels and more 'W' clips.

Fortunately the panels that did have the retaining wire on have survived intact so I still have half a greenhouse!
When I get my replacement panels I'm definitely going to put a retaining wire on them too.
Not sure there's much I can do about the door blowing off though..

Overall, I was initially pleased with my greenhouse, although it has become a Serious DIY project trying to keep it in one piece.

Was generally happy with my greenhouse but getting a bit fed up of retrieving the panels from neighbors gardens. I am now close to removing all panels until the spring and then using glue as a solution.

Perhaps it is reasonably good value for money but I worry every time there is a strong wind. There should be a proper fixing on the door to keep in closed.
