Beautiful Greenhouse with ready to use features!

I finally have my beautiful greenhouse! I have been gardening for many years using my basement and 3rd floor finished attic to start and grow seedlings. My new Poppy Greenhouse is perfect for my needs. It took me & my son-in-law about a month to build. The assembly booklet was easy to follow and all the parts fit together nicely. I sealed all the wooden parts first by using the Garden Box sealer. I highly recommend using a paint sprayer to do this ... I did. The greenhouse looks beautiful and it even has lots of shelf space and hookups for water and electricity. It was fun to build and I love 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!
