Over the weekend (and a bit elsewhen) I assembled a small greenhouse purchased from Amazon.

Here are a sequence of images taken from about the same position, showing the assembly (with more detailed pics following):

Let’s go back to the beginning. Here’s the 90 lb package:

I built a foundation out of treated posts I had on hand (concrete would have been better, but this should be fine):

I secured the posts to the ground with some heavy-duty metal spikes:

The base of the greenhouse:

The base is secured to the foundation with several lag bolts:

I added an optional accessory, a louvered vent:

Back corner:

Openable roof vent:

Gutter:

Base of the door, with a magnetic catch:

Inside:

Another optional accessory, an automatic opener for the roof vent, that opens or closes it based on the temperature inside:

The vent open:

The greenhouse feels pretty solid, and hopefully is anchored quite well, but I also added a third accessory, tie-down anchor cables to make it even more secure:

The cables go over the top:

Hopefully we’ll make good use of this over time. It could be very useful to get a head start on spring veggie planting, and more.
