Absolutely LOVE my greenhouse!!

I absolutely love My 11 x 7 poppy greenhouse!! The directions were very thorough and easy if you take it step-by-step. The craftsmanship and quality of the greenhouse is like none other! I am so in love! It is absolutely magical. I added my own, finishing touches to it to make it uniquely mine but all of the detail and accessories that it comes with are absolutely amazing. I may just move into it!!

Great DIY project kits

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!

Reasearched and this is the best

I have unpacked the boxes of my 6x9 poppy greenhouse. I now am going to seal the wood with Once-Seal wood sealer and then assemble. Just by the way it was packed, the quality of the pieces and the in depth instructions, i know this is one fine product and will be the perfect greenhouse for my urban back yard
