Greenhouses For Sale in Seattle, Washington

We have grown tomatoes, hot peppers, and experimented with kohlrabi, cauliflower, and broccoli.

The greenhouse improved our gardening experience because our growing season is too short to grow peppers outside. It has opened up a whole new opportunity for us. The greenhouse is being used at a high school, and the peppers get planted in the spring by the students. They are ready to be harvested and made into Hot Pepper Relish in the fall when we are back at school. It is perfect!

The buying experience was great. The greenhouse was easy to buy and put up without any issues. I didn’t need to deal with customer service because there were no issues.

We put raised beds around the outside of the greenhouse with perennial herbs and flowers. This works well for bringing in the pollinators and providing herbs and teas to dry. I also set up a drip hose on the inside, so the greenhouse is very low maintenance. I only have to check in on it every couple of weeks.

My favorite thing about the greenhouse is that I don’t have to worry about snow and wind. We get long, harsh winters, and I didn’t want to have to worry about it collapsing.

This is our first greenhouse, and inside we grow fresh vegetables including green onions, carrots, arugula, lettuce, and spinach, along with several varieties of fresh flowers and annuals for spring planting. We also use it to winter over several non-hardy perennials.

The greenhouse has significantly improved our gardening experience. It has allowed us to keep plants through the winter that we would normally lose, and lets us start planting crops earlier in the season—extending our growing window by two to three months. With the added shade cloth in early summer, we can keep more tender plants in the greenhouse before transitioning them to full sun. It also serves as a pleasant retreat in the in-between seasons—a sunny, warm spot to sit, read, or relax.

Our buying experience with Planta Greenhouses was great. We picked it up at a local warehouse and had no issues. At one point during the build, we called support and they were extremely helpful.

For upgrades, we custom-made wooden shelves to hold a large number of seed trays and plants. We also built a custom work table for potting and gardening tasks. The greenhouse is secured to large lumber beams with rebar driven through them for anchoring. Pond foam sealant was applied around the base to help with insulation. With the foundation we built, we think it can withstand just about anything.

Our favorite thing about the Planta Greenhouse is its durability and lasting build—not to mention how cool it looks. We always get…

I installed my first Planta Greenhouse, a Sungrow Compact, in 2024—but I use it a bit differently than most. Instead of growing plants, I grow custom-designed and hand-carved memorials and gravestones! My greenhouse serves as a year-round mini workshop where I carve, grind, and cut stone.

Living in a colder climate, the greenhouse has been a game-changer. I use it as a small annex to my stone carving studio, specifically for cutting granites and sandstones outdoors to keep silica out of my indoor workspace. The passive heating keeps me toasty—even when I’m wet grinding in February—and the interior is easy to hose down, which makes cleanup from stone dust quick and effective.

One of the most useful upgrades I added was installing galvanized bar grating as the floor. This lets water and stone dust drain through while still allowing me to move heavy gravestones around easily on dollies.

Buying my Planta Greenhouse was a breeze. Customer service was great, and I was able to pick it up directly from the warehouse.

Honestly, I love everything about it—the warm light, the comfort, the aesthetic, and its durability. I know I use my greenhouse differently than most, but I just wanted to share another unique and positive way these greenhouses can make an impact!

I installed my second greenhouse in 2024, finishing the build in late summer, so I haven’t grown anything inside yet. One of the main reasons I chose a Planta Greenhouse was for its impressive snow load resistance and overall durability against strong winds.

The buying process was smooth and convenient. Customer service was excellent—responsive and helpful throughout.

To improve stability, I anchored one end of the greenhouse to a concrete curb and installed tie-down anchors for uplift resistance. I also added a rain gutter as part of the setup.

So far, my favorite thing about the greenhouse is its ability to handle heavy snow and withstand wind loads. I’m looking forward to using it in the next growing season.

These are the greenhouses we need in colder Canadian climates. I am in zone 4 and have my Sungrow Compact set up for growing all year long! Had electrical trenched to mine and will have the Phoenix greenhouse heater ready to go for winter. I hired my friend’s son to put the greenhouse together for me- I do think you need to be good at building things to put this together. He put down a concrete foundation and then attached the greenhouse to a pressure treated wood frame. I also had him install one of the automatic roof vents which works amazingly well. Loving it so far.
