Garden Grow Polycarbonate Greenhouse Large Walk-in Garden Growhouse, Rust-proof Frame, Sliding Door & Supported Twin Wall Panels with Steel Base 6x4 ft (Grey)

I wanted a green greenhouse! In the pics this greenhouse looks like it's polycarbonate is green on the top. It's not. Having said that, the frame is green and good quality. Not the cheapest one but it looks good. My husband and son, who are more than capable of putting together items for the home and garden had a bit of difficulty putting this together. The instructions aren't all that clear and a couple of times it was put together the wrong way! Soon rectified it just took a couple of days to finish putting together. A couple of things didn't line up correctly but, having a handy husband, they were soon sorted by re-drilling the holes. If you want a green house which basically erects itself, you're not going to have that with this. However, once sorted, this greenhouse looks very good.

Having anchor-bolted the steel base onto raised blockwork on a concrete perimeter foundation (which had the additional advantage that the internal ground level could also then be lowered to provide extra headroom) and siliconed all the panels in place as recommended, April's storm Hannah had no effect whatsoever on the greenhouse other than slight shaking of the entire back panel.Unfortunately, the box that the greenhouse arrived in had been dented in transit by the carrier Hermes and although no obvious damage to the contents was apparent, it was only during erection that it was discovered that the outside of the rear central polycarbonate sheet had two slight dents, the positions matching the dents in the box to which it had been adjacent, but as the damage was only cosmetic (most noticeable when the sun catches the panel at certain angles) and installation would have to have been halted whilst awaiting a replacement, the damaged sheet was used anyway.Some of the protective opaque and transparent film on the polycarbonate panels was already coming loose in the box and in case the film came away completely prior to the panel being fitted into place, I temporarily put a small piece of white insulating tape on each UV-protective side to ensure the panels were installed the right way round. Several of the aluminium parts had slight manufacturing defects e.g. rails were dented but where necessary these were straightened out prior to installation. For the most part the written instructions and diagrams were fairly clear and straightforward and contained only one or two mistakes e.g. referring to the wrong diagram and it was useful to watch the website's installation video. For the most part I assembled the greenhouse myself but having a second person on hand to assist and hold parts when necessary was essential. Fixing some of the nuts and bolts was quite fiddly and having a spare socket on hand proved very useful. Following installation I discovered that rain gets through gaps between joints where parts meet at the four corners of the roof and which then pours down the corner uprights and into the bottom of the greenhouse but subsequent siliconing of some of the gaps has cured this.Be warned that the telephone support number is charged at a special rate which may not be included in a UK telephone calls inclusive package (I used it only once to enquire whether or not the protective film on the steel parts should remain or be removed and after being put on hold for a few minutes I was told it was up to me).I did end up making some changes/improvements to the greenhouse design:(1) To prevent pigeons etc sitting on the roof ridge rail and leaving droppings on the polycarbonate roof panels, prior to installation I bolted metal bird spikes onto an aluminium 'L' cross-section bar which was in turn bolted onto one side of the ridge rail (see photo).(2) After installation, with the roof window opened and resting on the stay there was nothing to stop the window sliding along towards the back of the greenhouse (where it then knocked off the roof apex plastic end cap) and when being closed it was fiddly to properly align the window with the opening. This was overcome by making sure that the window was in the right position and then drilling a hole and inserting a spare screw into the top groove of the ridge rail (which acts as a hinge for the window) just in from the end cap (see photo).(3) As there was a spare plastic washer and a spare nuts and bolts, I drilled a new hole in the centre of the top horizontal rear support rail and rear central polycarbonate panel to provide additional support.(4) Following installation the supplied nuts and bolts started showing rust marks almost within a matter of days. Unless the manufacturer starts providing stainless steel ones, these can be bought separately for just a few pounds and be used instead (which I would have done had I known that rust discolouration would occur so soon).(5) The supplied bolt and cap nut for the door catch were useless and kept working loose and if not re-tightened literally each time the catch was used the cap would fall off onto the ground. I ended up replacing the bolt and cap with a (stainless steel) M5 12mm bolt and cap nut bought separately.Overall and subject to the above comments, I'm very happy with my purchase and I see no reason why the greenhouse shouldn't last for several years. As sold the greenhouse certainly warrants 4 stars but had it already incorporated my changes/improvements it would warrant 5.

This greenhouse took 8 hours to build and required the excellent video on the makers website. The instructions need following extremely carefully. I built it on a base of 6 paving stones with gravel drainage channels and the four base spikes cemented in plus the base screw down to the paving slabs. It is now a substantial structure and has easily shrugged off 2 days of wind and rain. Absolutely delighted with the final structure and added waterproofed electrics.

We had fun assembling, but you need to get the base 100% straight, as not totally straight I had to modify things could not get the feet even , because of the position even with an impact drill, could not break through a flint stone, so slightly out of alignment, but as I come from an engineering background, my degree was able to adjust things, be warned they need to modify instructions, there are typos, and some diagrams have been updated on the extra supports in the roof, but next page they are not there, many errors on the document. For me I could work things out with a few mods, is like a meccano set but more difficult, not simple assembly, but happy with it with my modifications

The greenhouse came on time and the seller was helpful.However, a word of warning this was a project for someone who is an experienced DIY enthusiast.The greenhouse will only work if the base is 100% flat. I had to correct this when it was slightly off.You need a good small socket set for the nuts and bolts. Many of the nuts and bolts don’t fit together as they are cheap and poorly produced so you may want to buy some others or check the pairs match at least before trying to fit them together. It’s awkward and fiddly to do. The design is terrible and not at all user friendly.The instructions are terrible and need to be read but then figured out in a logical fashion after. Furthermore, the written and video instructions are different. I couldn’t find the video instructions online so emailed the supplier who did kindly get back to me and that is the only reason I would give this 2 stars.I spent about 10 hours, over 4 days, in total and needed a second person to support the framework as I built it. It’s a good project if you want to practice patience! I could have very easily smashed it into small pieces and taken it to the dump, in fact had it not been lockdown and all the dumps closed, that’s what would have happened. I was about to give up totally when I got a second opinion and gave up with the instructions and did what we thought would work. This meant drilling holes and adapting the design.I wish I had never bought this greenhouse but now it’s standing and has plants in it. I don’t hold out much hope for it lasting long as it’s flimsy and the first gale is likely to destroy it.

Don’t leave door open the panels broke in a storm bit cheap took ages to assemble
