    Planta Urban

    I purchased this greenhouse last spring and assembled it by myself. There are lots of nuts and bolts and it would help to have a second set of hands. Slow and steady is the trick. The final result was excellent and I had a successful summer. This past winter we had over 10 feet of snow that was collapsing roofs in the Barrie, Stayner area. The design and construction of the Planta greenhouse withstood a heavy snow load and I’ve been harvesting herbs and greens since March. I highly recommend this product.

    Thank you so much, Chris! We're absolutely thrilled to hear that your Sungrow Urban has been such a fantastic investment and that you successfully tackled the assembly solo.

    What's truly impressive is how your greenhouse weathered that extreme winter with over 10 feet of snow in the Barrie-Stayner area - especially when other roofs were collapsing! That kind of performance under such harsh conditions really showcases the strength and durability of our design and construction. We're so proud to hear it stood up to that incredible snow load.

    Thank you for choosing Planta and for sharing such encouraging feedback about your experience with the Sungrow Urban through all seasons!

    Well designed for DIY

    Going on the 4th season. It has held up well to our harsh winters and windy conditions in Eastern Wasington State. Assembly is not difficult. The YouTube videos are very helpful. I was able to run power and water to the selected site. The stamped holes lined up perfectly for screws. LOTS OF SCREWS/BOLTS! I had a few things I had to redo because I initially put together incorrectly. Once you get the process down using the videos for step by step "how to" it goes well. A quality product worth the time invested to complete. Once the site is prepped the way desired, 2 fairly handy people can get this put together and ready to use in 3 days. A kid or 2 for "go fer" etc. is helpful.

    Thank you so much, Jim! We're absolutely thrilled to hear that your Sungrow 20 has been holding up so beautifully through four seasons of harsh Eastern Washington winters and windy conditions - that durability is exactly what we strive for!

    Your experience perfectly captures what makes our greenhouses so special for DIY builders. We love that you found the YouTube videos helpful for getting through those step-by-step details. It sounds like you really got the hang of the process, and we're glad those stamped holes lined up perfectly for you. Don't worry about having to redo a few things initially - that's all part of the learning curve, and it's clear your attention to detail and persistence paid off in the end.

    Thank you for choosing Planta and for sharing such detailed feedback about your four-season journey with the Sungrow 20!

    Best investment we could have made!

    Going on three years now for our 10 x 13 , growing produce, herbs and fruit trees in my SUNGROW. I wish I bought one years ago. So grateful I made the leap. Anyone who wants to grow beautiful plants need to buy one. So strong, through winters, strong winds, high temperatures and EXTREME SUN, our Greeny is like new! The panels are clear and the compliments we receive makes me very proud. Heated all winter our produce is so tasty all year. The plants just love it, the Govee lights rock her, the look is so pleasing to look at. Worth every dollar and thinking about adding on, we love it so much ❤️Customer service is A + Always there to answer any questions you have, and super nice. This addition into our Windsor Ontario property is the best decision we ever made. Make it yours too.....

    Love our Sungrow!

    Our Sungrow 20 went up a week ago with help from a Planta certified installer, and we’re super impressed with the quality of the greenhouse and with the installation. Still lots to do before planting, but we’re getting closer!
