The Greenhouse


A fairly scenic place for a garden…

I’ve been wanting a greenhouse for a couple of years now, and this spring we finally made it happen. Warm weather crops like tomatoes, peppers, cucumbers, and the like are nearly impossible to grow here in Alaska without a greenhouse. While I’ve been able to successfully grow tomatoes, sweet corn, acorn squash and pumpkins here in Alaska without a greenhouse, it has required raised beds, hoop houses, and some serious luck.

With a greenhouse, we should be able to grow much healthier, productive plants.  New veggies mean new challenges, which always makes for an interesting growing season.

The greenhouse is 16×10 feet, with seven foot walls. The peak of the roof is probably 10′ high. I built the floor for the greenhouse last fall just before the snow began to fall. The floor is built on 4×6 skids, supported with “linkin-log” style 2x6s underneath to keep it level. We have a pretty good slope to our yard, so while one side is ground level, the other side of the greenhouse is 4′ off the ground.

I threw a tarp over the floor this winter, then shoveled off the snow in March in order to build the walls and roof. My father-in-law had old fiberglass greenhouse panels that had been sitting in his yard for nearly 30 years. Although they were completely buried in leaf litter, they still had some life in them, and saved me over $1000 dollars in supplies. An acquaintance was getting rid of a very nice glass french door a couple years ago, which provided a beautiful (and free) entrance.

I ran out of old fiberglass panels before I got to the last side of the greenhouse, but because that side is north-east facing, with the mountainside behind it, I just covered that side with plywood that I’ll paint this summer. We shouldn’t lose much light, as the sun never shines from that side.

I haven’t built benches yet, but that project may wait until next year. For now, 5-gallon buckets on the floor should work just fine.


The plan this year is to grow 30-35 plants in the greenhouse. We’ll have a good variety of tomatoes, peppers, and cucumbers. The boys want me to grow sweet corn and pumpkins, so we may try those in containers as well. The greenhouse has already been up to 74F this week, with ambient temperatures only in the 40s, so it won’t be long!

All the best as you get ready for growing season!

    Looks nice. I am planning on building one very similar in design. Good luck
