Sungrow 32

We installed our first greenhouse in 2022 on our high plain homestead at 9,500 feet elevation in the Colorado Rockies. At this altitude, even the warmest summer nights rarely get above 50°F, and strong winds can reach 60–80 mph with several feet of snow in the winter. Growing anything outside is nearly impossible—most crops either freeze or fail to grow due to the wind chill. We knew we needed the strongest greenhouse possible to withstand these extreme conditions.

After extensive research, we chose a 32' Sungrow kit from Planta and added two extension kits to make it 48' long. To ensure durability and year-round usability, we anchored it to a 4-foot underground foundation made of concrete blocks, effectively turning it into an underground greenhouse. The earth and concrete walls act as thermal mass, storing solar heat and helping to maintain nighttime temperatures without the need for extra heating. Even in winter, the inside stays 20–30°F warmer than outside, though it still drops below freezing.

In the coldest months, we repurpose the greenhouse to house small animals. Chickens and rabbits live inside during the winter, providing fresh eggs and natural fertilizer for the soil, ready for spring planting. It’s a bright, spacious environment that keeps them safe and warm while making the most of the structure during the off-season.

The greenhouse not only functions well—it looks amazing. It's become a multi-purpose passive solar building, and in winter, it turns into a…

We installed our Planta Greenhouse right next to our garden, and it’s been a fantastic addition to our growing setup. We use it to grow a wide range of crops including winter melon, cucumbers, cantaloupe, tomatoes, chayote, and bitter melon. One of the biggest advantages has been the extended growing season—it’s allowed us to get more from our plants, especially in a region with strong winds and occasional heavy snowfall.

The purchasing process was smooth and easy, with excellent customer service throughout. Before setting up the base frame, we built the beds and lined them with dead hemlock and cardboard to help retain moisture. We also installed gravel and proper drainage around the outside, which helps keep the soil inside well hydrated.

The greenhouse has proven to be strong and secure. The panels do a great job of transmitting heat, and the automatic vents regulate the temperature well. We're so pleased with how it’s performing that we’re considering adding another one next year. I’ve already recommended Planta to several people—it’s been a game-changer for us.

In 2024, I installed my first greenhouse with the goal of creating a true four-season growing environment in Northwest Montana—and the experiment was a success. The greenhouse is equipped with hydronic radiant-heated beds and air heat powered by an outdoor wood boiler. A 5000 CFM exhaust ventilation system and 50% shade cloth help regulate ambient temperatures during the hot summer months, keeping conditions within optimal growing ranges year-round. With careful planning and the right systems, this greenhouse shell supports nearly any fruit or vegetable, regardless of the season.

The structure includes raised beds, a radiant-heated table for starts, shelving, and a thermostat-controlled setup for heating and cooling. I’ve also integrated grow lights and a timed irrigation drip system. Buying from Planta was easy, and customer service was great throughout the process.

My favorite part? Harvesting fresh greens and herbs in the dead of winter. If you're considering a similar four-season setup, I’ve learned a lot through this build and would be glad to share insights.

This is my first greenhouse. Inside, I've grown tomatoes, strawberries, carrots, lettuce, pole beans, squash, zucchini, cucumber, sweet and spicy peppers, sugar peas, cantaloupe, onions, sunflowers, and zinnias.

In my area, gardening comes with its challenges—rabbits, rodents, deer, and antelope, plus unpredictable weather, night freezes, and high winds. My Planta greenhouse has been a game-changer! It allows me to grow almost anything I want, extending my growing season from early spring to late fall. I couldn’t be happier with it!

Ordering was easy, delivery was on time, and the Planta Facebook page was incredibly helpful when I had questions about assembly and use. I also enjoy seeing all the shared photos!

For upgrades, I created raised beds on both long sides with a rock path down the center. This setup works perfectly for my needs.

One of my favorite features of my Planta greenhouse is its sturdy design, which stands up to high winds and unpredictable weather. I also love the doors on each end for air flow during warm days. But my favorite is during the off-season, when I can store my outdoor furniture and garden supplies without worrying about damage. It's that roomy.

Thank you, I love it!

We grow a mix of herbs, flowers, and vegetables. One of the biggest improvements has been the ability to extend our growing season. The greenhouse offers protection from extreme temperature swings and animals, which has made a big difference in our gardening results. It’s also become a relaxing hangout spot for my wife and me.

Our experience buying from Planta was excellent—great communication and customer service throughout. We originally purchased a 26-foot model and later extended it to 32 feet. Since then, we've added shelving, created a sitting/work/storage area, and installed automatic vents. We're also considering adding fans in the future for additional ventilation.

Our favorite thing about the greenhouse? It consistently lives up to the advertisements. Thank you, Planta.
