A heat-sensitive automatic roof vent and louvered base wall vent work together to maintain optimal temperature and humidity levels.

My love and I, anticipating the challenge, built this greenhouse together and we are so happy we did. It comes in 5 boxes weighing around 96 lbs each. We were very organized and it took around 3 days to build. We suggest you don't remove all materials from the boxes since the instructions tell you which box the part is in and it takes quite a bit of space to build each section. We did spread the screws, fasteners, etc out on 2 tables, which also helped with organization. We had never built anything before and it took patience, but it was well worth it and we love the quality of it!!. Julie. Stoneville, NC. Sun Jun 22 2025

We absolutely love the look of this greenhouse! The wood came in pretty good condition..only one small piece was broken but we were able to glue it and it got covered later anyway.

Just got it up a few months ago . Easy construction to put up with two people . Have not had any issues with it yet. Not as “hot” as glass so I will need a heater in my climate . We did our own base .. Anonymous. Carleton, MI. Fri Dec 16 2022

Great kit with quality parts and wonderful customer service. Make sure you clearly sort and label everything before you begin. Also have your foundation ready as it takes longer than you think. You should go to the Palram website and download the instruction manual before your order arrives and get prepared. For us, there was no way we could have put this kit up in half a day and we're still chuckling about that! We were stumped a couple of times, but customer service support from Palram easily helped us each time. It came out perfectly and I would easily give it five stars, but there are are a few things I would do differently on a Greenhouse of this quality and also . . . the kit instructions . . . a few extra words would have helped greatly instead of 99% photo instructions. Now on to planting!. Cassandra. Prescott, AZ. Tue May 10 2016

Fence lines and HOA rules don't have to limit your gardening dreams. Vego Garden greenhouses embodie the classic Nordic style in a purposefully shorter height, making it the perfect choice for bringing your vision to life, no matter the constraints.

[This review was collected as part of a promotion.] The roofing has too many caulking you have to do. I missed a few spots using a caulking gun, the water comes in when it rains. I still searching for those spots i missed ( might get worse in the winter). The door is not fully sealed, there is a gap everywhere, the door latches fall against the glass wall when you unlatch and the latches are not oriented correctly when you try to latch it to the door..

I’ve had this greenhouse for over 3 years and it has held up well and looks amazing. I really love it. I did not, however, love the assembly. My husband and I were able to manage it ourselves but boy was it stressful! There were parts missing and we had to contact the company several times. They were really helpful and sent the parts but getting this thing together was a challenge.. Alicia. AZ. Mon Sep 30 2024

This portable greenhouse was easy to assemble with the family (labeled parts, done in just half a day). Our backyard gem turns family gardening into pure fun!

1. Latches on the door are difficult to install 2. Instructions are not clear and need more written details . Suggestions 1. prewrap windows 2. Minimize pieces 3. Create a video that walks customers through steps by step Took 11 hours to complete with 2 people Overall it is a nice build, sturdy . The quality of the materials are okay but not great quality. But will get the job done. Like that everything is pre drilled and numbered. The most difficult part was the lack of instructions. Jeannie. Midlothian, TX. Fri Dec 05 2025
