really enjoy the produce we are growing
Thanks so much, Billy! We're thrilled to hear you're enjoying the fresh produce from your Sungrow 20. Nothing beats the satisfaction of growing your own! 🌱
Let me start with, we LOVE this greenhouse! We spend our morning coffee in here, let our cats hang our with us in here, it's great. I'm going to write a very honest review! Before you look at my star rating and get scared away, I'm very peculiar and strive for excellence. Is something is worth doing, do it right! Go above and beyond.
1st-The Doors:
You have to open the windows above the doors to open the doors. Very annoying but I understand the concept of the opening the windows for ventilation. I'd rather have 2 roof vents be included and just have full size doors.
2nd-The Frame Across the Bottom of the Doors:
There is a frame piece along the bottoms of the doors which was tripped over many times. We ended up removing that piece after installation was complete. It's sturdy enough to not worry about needing that piece there, but now you may have some sealing issues.
3rd-Door and Window Sealing:
The doors and window has massive gaps that will require out of pocket cost for a foam weather stripping.
4th-Poly Sealing.
No way in heck are you going to seal the poly wafers with tape, I took 13 hours extra and filled every single poly hole with clear silicone to prevent moisture in the poly.
5th-Window Vent Back Order:
We spent a small fortune on ordering 4 automatic window vents, it's been almost a month and have yet to receive them. We can't leave for camping for the weekend until we receive them as all out fan and heating equipment is automatic. So those auto window vents are…
Hi Christie,
Thank you so much for your thoughtful and honest review — we truly appreciate the time you took to share your experience and feedback in such detail. We're thrilled to hear how much you’re enjoying your time in the greenhouse and that it's become part of your daily routine!
We also understand your concerns about sealing and setup, and you're absolutely right that proper sealing can make a big difference. For future reference (and for others reading), we’ve put together a helpful guide on sealing techniques and weatherproofing that may help: https://plantagreenhouses.com/blogs/learn/the-essential-greenhouse-sealing-guide-tips-for-a-leak-free-garden
Thanks again for the insights, we’ll definitely pass them along to our product team. And we hope your Sungrow continues to serve you well through every Alberta season!
The experience has been excellent from the very beginning. From tomatoes and cucumbers to peas, we’ve been able to grow an incredible amount thanks to the optimal conditions inside the greenhouse. The growth is rapid, the harvests are generous, and the growing season is significantly extended.
The purchase process was easy, and the staff at Planta were incredibly helpful. They answered all of our questions before we made the purchase and continued to be responsive and supportive during the assembly phase.
We added raised beds to make planting and maintenance easier, and one of our best decisions was including the automatic roof vents. They open and close on their own and do a fantastic job regulating the temperature inside.
I truly love everything about my Planta Greenhouse. Living at a higher elevation with plenty of snow and wind, durability was a top priority—and this structure delivers. It’s so well-made and performs exactly as advertised. I highly recommend Planta to anyone considering a greenhouse. Most days, you’ll find me happily gardening inside—my new favorite place to be.
This is my first greenhouse.
In 2023, I installed the greenhouse. Inside, I grow tomatoes, carrots, and cucumber.
Super greenhouse.
My experience buying from Planta Greenhouses was great, no problem, very fast shipping.
It’s completely transformed our gardening experience. Inside, we grow tomatoes, peppers, ground cherries, and cucumbers. It’s been a whole new world for us—starting seeds, extending harvests, and seeing real results even into November. Normally, our growing season would be done by the first week of September, but not anymore.
Buying from Planta Greenhouses was amazing. The delivery was fast, and any time I needed help, they were there to support me. While I’m not doing anything fancy inside, I’ve added side shelves to help with starting seeds.
I love everything about this greenhouse. Living in Zone 3, I had never been able to grow cucumbers successfully, and I was always disappointed with my tomatoes. This year was different—I harvested so many huge tomatoes that I actually pressure canned them. I had more cucumbers and peppers than ever before, and I was amazed to see my ground cherry bush grow over four feet tall and produce an endless amount of fruit.
One of the best surprises has been how much I enjoy simply being in the greenhouse. When it’s -20°C outside, it’s +29°C inside. I’ve spent time in there lounging with a book and coffee, soaking up the warmth and getting a suntan in the middle of winter. Absolutely amazing. Every part of this experience has been my favorite!
