Great Design!

I absolutely love my new greenhouse. The automatic ventilation and the hose spigot are excellent features that really help manage the plants I keep in there. The design is aesthetically pleasing and the polycarbonate appears to be really durable. Looking forward to all the things I can grow in my greenhouse.

Graet Greenhouse

This is a great greenhouse. It took a while to assemble but I'm 75 years old.It was well worth it. Seems very sturdy and the fold-able shelves are a nice touch. With the fan and two operable windows along with the vents temperature can be reasonably controlled. I would definitely reccomend

Awesome for Alaska

What a great greenhouse! I bought it for the snow load and wind specifications since I’m in Fairbanks Alaska. I shipped it up through Carlisle Connect without any issues. Staining the greenhouse took two solid days as there’s so many pieces but everything was well marked, instructions were very easy to follow. I used a stain color called “cedar.” The vents and fan seem to work really well to cool it down from the intense sun. It also holds heat pretty well overnight. I bought this last year so it’s gone through one winter and held up perfectly. I really enjoy going and working in this space. Highly recommend!

Excellent quality.

Still under construction but so far I am very impressed with the build and quality of the greenhouse. It requires patience and time to put together but b using the book makes every step easy. Also with only walls and windows installed, it survived a massive wind storm.

Our new Zalie looks so great!

We love the Zalie! We have had it installed for about a month now, and it is perfect for a potting shed and a place to start seedling and winterize plants. installation was very straight forward, I was able to install it all myself, except for the steps that require another set of hands, and they are very limited. I did have a number of times where I was sure parts were left off... but they were all there, I had just not found them yet. Stay organized!! Truly a beautiful addition to our back yard.

Perfect lil green house thats affordable too.

I purchased this green house in march, came in a little under 2 weeks and dropped in my driveway. I built the whole thing pretty much solo, taking about 3-4 days. I dug a somple PT treated dimensional lumber foundation by digging trenches, laying some gravel and setting the lumber in the trenches to the foot print of the green house. There are lots of parts, and i highly recommend organizjng everything first by number and setting it up as close to where your going to build it (stupidly i walked back and forth between my driveway and the site every time I needed a piece) Anyway, the green house came together great! I believe at the sale discount, this is going to be cheaper than buying your own lumber and design/building it yourself.

Love it!

I truly love this little greenhouse . It was Extremely well-made . Easy to follow Built app and paper directions . All pilot holes Etc. lined up perfectly . My only Recommendation Would be changing the directions for roof assembly. The direction showed Silicone and screwing down the roof after it was assembled . Not sure how To do that after it's assembled at that height . Fortunately I have a 6ft 7” brother-in-law that helped Lol Other than that Super happy with the purchase even with that being said would buy it again!

Great Cost Effective Option

After pricing the lumber to build our own custom greenhouse, we realized what a good deal this was. We expected it to be on the flimsy side, but we were pleasantly surprised at how sturdy it is. The instructions were clear, everything was labeled well, and we received all the pieces we were supposed to. The build took us about a week - including adding stain/sealant. All the holes aligned and builder hubby was surprised at the tight fits and alignments. The only hard part was caulking the roof panels. The inside is adorable - and plenty big enough for our needs. It's amazing how many extras (like the fan and heat sensor and adjustable shelves) are included in this price. We are extremely satisfied with this product, and highly recommend it.

She's a beauty!!

I'm not going to lie, when I opened up the boxes to start sorting the wood and hardware I was dismayed at the number of parts. I thought "what have I gotten us in to???". My husband and I have built many things together over the years and we are pretty handy but it did seem overwhelming at first. The first day we tackled the construction of the four walls. We did make a few mistakes and had to undo a few steps and start over. We learned that you have to really pay attention to the details of each photo to make sure that the pieces are facing the right way. Each step after the walls was actually pretty fun and went much faster than expected. We started on a sunday afternoon and worked each day until dark after work hours and finished the following Saturday. I'm really in love with it. It's beautiful, it's sturdy and it smells great. I haven't "used" it just yet but I'm having fun decorating the inside. My husband was really impressed with the fact that all of the pilot holes were drilled in the correct spot and lined up. All of the parts were accounted for and there was more than enough hardware. I have always wanted a greenhouse and I'm very happy with this purchase!
