My wife loves it. The two of us put it up together in October, it took about three 8 hour days but one day was partly getting the ground ready. Pretty easy if you just follow the videos online. Installed the self opening windows this spring and everything is working great. Couldn’t be happier. Highly recommend
Thank you for sharing your experience! It's wonderful to hear that you and your wife are enjoying the greenhouse. We appreciate the recommendation. Happy gardening! 🌿🏡
I really appreciate having the greenhouse. It was a challenge to assemble, but very rewarding after completion. I planted from seeds and within 3 days, radish had popped up and within 1 week cucumber also came up from seeds. Now everything is growing with gusto and I have received so many compliments on the greenhouse. It has only been finished for 2 weeks and it's the end of August 2023. Thanks Planta greenhouse!

Result for 1st year: cucumbers- July to October too many. Eggplant -about 50 lbs. Sweet pepper 2 buckets.
We installed our greenhouse in 2021 and right now we are starting the new garden for 2022, so we’re growing seeds and other plans that can’t handle the cold. I believe it will add to the times we can grow. With the heater we bought with the greenhouse we should be able to grow year round. The stability of the greenhouse is really good even in the wind. And we had snow just this week (February) and it is holding up perfectly.
My buying experience from Planta was good. It was challenging but rewarding to work through the instructions and also follow online video instructions for putting the greenhouse together. I’d recommend using both the paper manuals and online step by step videos when putting it together. If possible, have more than one person to construct the greenhouse. I was able to do it by myself but I’m sure it took quite a bit longer.
