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!

Quality Product

I was impressed with how every part precisely lined up and went together. The placement of the 1,000 pieces was definitely based on fit, not the order the boxes were numbered. I started with box 1 and had to go to possibly the last box to find a part. So my advise is to lay out all the parts alphabetically and numerically and in a way that can be covered in the event of rain or wind. I would have probably saved about 10-15% of my assembly time not having to search for the right parts.

Wonderful Greenhouse

We are thrilled with our greenhouse! It looks fabulous in our yard. The quality of the materials is wonderful. Our main purpose is to over winter outdoor plants and be able to start spring seedlings outside. Although it was many steps to assemble, the directions are straight forward. We used the paper and Bilt directions. Total actual build time was about 14 hours. Our only issues were weather related. Unable to doing all the sealing of the wood and the sealant on the roof panels to due extreme heat and humidity (Florida in the summer), We added a small patio on front and ran a water line from the house. We have started fall seedlings and look forward to doing all are spring seedlings and overwintering our outdoor plants. We never write reviews, but felt this product was beyond our expectations.

Perfect little greenhouse

Perfect little greenhouse! Spent the rainy weekends sealing all the pieces. Put together the frame and transported it to the garden, then from there added piece by piece ( there is A LOT of pieces) until it was completed! Worth all the work! Now time to start growing!

Smells so good!

This greenhouse is amazing! Good quality and easy to follow instructions. There were only a couple of things I would've changed in the assembly instructions, but overall excellent!

Awesome Greenhouse!

This greenhouse is extremely well designed and engineered. My son-in-law and I built it together. We did a strip foundation or "wall footing" to anchor to on a Friday before a Monday build. The build took us 2.5 days and was very straightforward. All parts have inked stamps for the part numbers to keep organized. We laid out the parts with like numbers and design and that worked for us. Also, we only had two times when we were scratching our heads, but after a little thought, we were just looking at it from the wrong angle. My wife is extremely happy with this greenhouse! We literally just went through a 20 degree night and with a heater the temp was low 50's. I highly recommend this to anyone. Follow the directions to a "T" and you'll be fine.

My sanctuary

My new sanctuary for sure!!It has everything I need. I have a radio always playing for plants,and lights at nights, a fan when it’s hot ,and running water!! It is magical in my 11x7 Poppy’s greenhouse that was so easy to put together. We have weather sealed it.

Great Product, Complex Assembly (But Worth It)

Backyard Discovery 9x6 Poppy Greenhouse Review Assembly This isn’t a weekend “pop it together in two hours” kind of project. This is an adult LEGO set on steroids. Every beam, panel, and bolt has its assigned place, and the instructions will happily test your patience, eyesight, and ability to distinguish “Panel A” from “Panel A (slightly shorter).” My advice: treat this like a marathon, not a sprint. Lay everything out, stay hydrated, and keep snacks within arm’s reach. The trick is not to hurry—slow and steady wins the greenhouse. Quality & Design Once assembled, though? Wow. This isn’t just a greenhouse—it’s backyard jewelry. The cedar frame is genuinely gorgeous, sturdy, and smells like you just stepped into a woodshop. The polycarbonate panels let in light beautifully, turning the whole thing into a glowing lantern by late afternoon. It doesn’t feel like a plastic garden gadget—it feels like real architecture. Practical Use Inside, it’s surprisingly spacious. The 9x6 footprint is enough room to start seeds, baby your tomatoes, or indulge in a nursery shopping spree without judgment. Ventilation is well thought out, and the frame feels solid even when the wind picks up. It’s not exactly storm-shelter material, but for everyday garden life, it’s more than up to the task. Packaging Notes If I could change one thing, it would be how the parts are packaged. Right now, the system feels designed to ship neatly for the company—not to build easily for the customer. You’ll find yourself opening Box 3 for a part you needed ten steps ago, then rummaging through Box 1 for its matching bolts. It would be far more user-friendly if each stage of the build came grouped together, even if it meant a few more boxes. The greenhouse itself is worth the work, but the packaging could definitely do more of the heavy lifting in helping the builder stay organized. The Verdict Would I do it all over again? Absolutely. Building it takes patience (and maybe some light cursing), but once you step back, the effort feels completely worth it. It’s beautiful, functional, and oddly satisfying to know you built it. ⭐️⭐️⭐️⭐️⭐️ Five stars for the product. Four stars for the temporary hit to my sanity during assembly.

Just one small issue

Just had a couple of young men assemble this greenhouse for me. It is beautiful! They did it in 2 1/2 days, installing it on top of an 8x12' deck. My only issue so far is that I cannot get the fan to operate correctly. I set thermostat to come on at 80 degrees, but even at 58 degrees it just runs constantly. Will be contacting Customer Service for help.
