  • Little Cottage Company Colonial Gable Greenhouse, 10′ x 16′, Primed Tan – For Zone 4, 5

I like the fact that is way better than expected. It made it through some crazy winter without fuss. We did put heat in it to keep plants alive but it is my favorite thing ever.

The materials, design, strength and construction rate is A++.

It is made in the USA with great craftsmanship.


Panelized walls sections saves time when assembling and it comes with a fully illustrated manual.

The Lp smart side sliding and trim is primed and ready for paint. We painted ours before we assembled it.

However, it does not come with a floor kit but you can build your own foundation.

There are lots of functioning windows and transom windows with corrugated polycarbonate roofing.

  • Palram HGK144 Glory Greenhouse – For Zone 6, 7, 8

I got this because brand because they have anchors. With the hectic snow and wind here in Washington state, it’s needed.


It took me about 10 minutes to get all the parts and put them in numerical order. However, it did come with pictures on how to assemble this.

They are stupidly easy to follow though. I put in an auto opener in the fridge before doing the installation. When it’s cold the roof window will close.

As the greenhouse heats up inside, it will open. It really is automatic! Wear gloves while putting that hinge together (the metal will cut your hands). The louver window has to be oiled, like a lot, to get it to work. I love having this space for doing my starters and transplanting.
