Really nice cold frame but....

I found assembly extremely difficult. I am trying to find out if the newer models have become more user-friendly in this regard. I grew greens year-round in Northern NM for several years with this--just piled on blankets at night in the winter!

Top Notch Product

I purchased an earlier version of this greenhouse about 8 years ago, and it has served me well through tough winters in Utah and Montana. The optional self-opening vent is a necessary accessory in Western climates with cold nights and sunny days.

great coldframe

I use this in the spring for planting lettuce and then as an intermediate spot for plants started indoors on their way outside. I have it on a 2' high raised bed which makes it easy to reach, has good soil in it and helps keeps pests out. Great with the auto vent opener (the small one). This has been performing well for us for several years.
