No more weeping for my Willow!

Absolutely love my new greenhouse! It is exactly what I have always wanted. First of all, love the design. We live in the mountains in the Shenandoah Valley of VA, so we built the decking platform in advance. We enlisted some friends for our building weekend. Taking the time to open every box & lay everything out and organize is key. As so, many of said, everything is clearly labeled and align with great detail. Keeping it square is crucial in the end! We spend a good 2 1/2 days to complete it of course, then I started customizing! We put insulation down on the floor and then laid finished pine on top, which I stained darker for contrast. We also are adding a small sink that we will find very useful. It’s as tight as a drum and we’re so excited for spring. Great product and great value. Highly recommend!

I built my Willow solo!

I purchased my Willow 9x6 greenhouse in July but waited a few months to build it. It was too hot here in southern California to comfortably do that kind of work in the summer. In the meantime, I put Penofin stain & sealer penetrating oil on all the wood components. All the parts arrived in perfect condition. As a 65 year old woman (able-bodied with fairly basic DIY skills), I am proud to say that I constructed the entire greenhouse myself -- zero assistance from anyone! It's my first project as a retiree. The instruction manual is detailed and well illustrated. Whenever I was not precisely sure about something, the BILT app clarified the situation. I mostly followed the instructions closely. The exception to this was roof construction. Because I was working solo, I couldn't build the roof and then hoist it into place. Instead, I simply first installed the purlin cleats and rafters and then attached the purlins to them (a much easier method, I think). My Willow is anchored to a foundation of pressure-treated 4x4s that are attached to 8 buried 29-lb concrete piers (metal straps shortened with a hacksaw). I made the floor of square 12-inch concrete pavers and gravel. The most difficult aspect of this project was installing the metal splice covers and the metal trim around the edge of the roof -- they lack pre-drilled holes and I'm not particularly comfortable standing on the fourth rung of the ladder. I am thrilled to finally have a greenhouse! It's something I've wanted since I was a kid. After over a year of shopping online (investigating all the possibilities for small greenhouses), I decided to purchase the Willow because it had consistently excellent reviews that mentioned the quality of materials, clear instructions, and attentive customer service (I didn't have to consult customer service!). Although the price has increased by $200 since I purchased mine, I still think it's a great value. Now, I'm excited to fill it with plants. In the summer, I expect to need to cover it with shade cloth.

Ideal size and quality.

Well designed, quality wood, and love the built in vent fan. This is the ideal size greenhouse for our property.

Solid quality.

I just finished building my greenhouse and I am so happy with how it turned out. The instructions were extremely easy to follow and it was a labor of love well worth it! Solid quality.

This is the ONE!

I absolutely love my Zalie greenhouse! Fairly simple to build, instructions are incredibly clear. Added a Dreo heater for the winter and moved my succulents in last night. Can't recommend enough!

Zalie Greenhouse

Highly recommend - easy to build and comes complete with extra parts and no damage! Wish they had a version with no poly on the north wall where no sun hits but follow along on my YouTube channel to see how I improve coloradogriit.
