I would give this greenhouse 5 stars if I could, but it was quite difficult to assemble and needed both myself and my husband. It took us a weekend to complete it. You also need to build a base if not included. The result is a lovely little greenhouse and it has stood up to the winds and gales we have had recently. We did reinforce the panels with glass tape and so far we have had no leaks, also the window has a very strange closing. For the price I paid I am delighted with the purchase and would buy another, it may be easier to assemble next time!. Susan. Lancashire. Sun Jul 14 2024

Transform your garden with the Poppy Greenhouse – the perfect space to nurture your plants and your passion for gardening.

I ended up purchasing the 11x7 Poppy greenhouse over the Memorial Day weekend, after reading a multitude of reviews. Based on those reviews I decided to give Backyard Discovery a chance. From delivery to final build I could not have been happier with the experience. As a DIYer, this was in my wheelhouse. What was most impressive was the build instructions, which were complimented by the online 3D app. The inventory list for each box was invaluable in saving time from having to look for the multitude of parts and hardware. To make the build easier, I set up a 6ft table in my garage and placed all of the hardware in plastic containers which were arranged numerically. This preparation will save an enormous amount of time searching for specific hardware. The quality of the cedar was very good, solid, and consistent. Throughout the build, the instructions actually had notes, in red, that were important “lookouts” so as not to make an error with regards to specific part orientation or sequence. As I worked my way through the build, the more impressed I became with the instructions and how I could tell that the folks responsible for the instructions were truly hands-on common sense engineers. My hat off to the company for their efforts in making these projects enjoyable along with providing a wonderful finished product…that appears to last. As with any quality build, if you do not ensure that the pad is level and the sidewalls are not square and level, you will not have an enjoyable experience. Backyard Discovery has hit a grand slam with their kits. Thank you for an enjoyable experience and wonderful sense of accomplishment that my wife will use and enjoy for years to come!. Ppjp1660.

Quality of the wood is poor. No predrilled screw holes, which makes it hard to put together as most need to be in on an angle. The build instructions aren’t the best either. Once built it looks good and does the job perfectly but isn’t worth the almost £1,400 I paid. Very disappointed .. Janneta. Lytham St. Annes, GB. Mon Jun 22 2026

Nice greenhouse but got so far and had to ask a friend, who’s an engineer, to help as instructions just pictures and not clear. Built a base with black grids and pea gravel. Hammered ballast stakes into ground and drilled holes in frame. Secured with metal angles pieces. My only disappointment is the window does work on 5 angled options, there is nothing for the holes in the latch to sit on to support the open window.

The greenhouse is a beautifully designed grow house that will become a real focal point in your garden. It has a unique design that lets the gardener access their plants without going inside the greenhouse. Designed to be positioned in an open space or against a wall or fence, the four opening doors can be hung depending on the access required. Combined with its relatively small footprint, this greenhouse is suitable for all sizes and styles of garden. With space for 2 grow bag trays on the floor and slatted staging that can be slotted in and out as required it gives a huge amount of flexibility and potential for growing a wide range of products in a relatively small space. Opening windows help facilitate airflow and enable temperature control and an auto vent is included to control one of the windows automatically. The safe styrene glazing means there is no risk of shattered glass and the timber used has been Pressure Treated to give it a 15-year guarantee against rot and fungal decay. The greenhouse is made from smooth-planed timber giving it a natural timber finish but can be painted to create a decorative feature in your garden. The greenhouse comes with fixings and full instructions for easy self-assembly. The greenhouse is available to order without an auto vent.
