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!
Hi Kay, we're delighted to hear that your greenhouse is thriving and that you've received compliments on it. 🌱🏡😊
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.
I installed planta greenhouse in 2021 & I grow houseplants, tomatoes, and peppers. I will also be starting seeds. With a greenhouse, I will be able to start veggies early and keep growing some all year round. What I love most about my greenhouse is that it is always a sunny, warm place to hang out. I can have more outdoor plants without having to let them freeze or find a place in the house for them during the winter. This green house is very durable. It has already held up to our 80 mph winds in Kansas.
I am so happy to report it is standing up to our harsh Kansas weather very well!!
I installed my Planta Greenhouse from Dec 2021 to Jan 2022 and I grow seedlings and flowers. The greenhouse helped to get planting started earlier and end later in the seasons.
My experience buying from Planta was very good, no issues. The greenhouse itself has good engineering and design.
To someone considering buying a Planta Greenhouse, I would say – Planta has the best selection. Get your land level as soon as you can before starting and take your time putting it together.
We installed our Planta Greenhouse in 2021. I have been growing tomatoes, lettuce, gourds, pumpkins, and papaya. So far, it extended our growing season and helped keep plants safe in our heavy winds.
Our experience buying from Planta was easy, if anything was wrong or missing the customer service team looked after this right away.
To someone considering buying a Planta Greenhouse, I would say – Go bigger at the beginning. It’s much easier than expanding. The greenhouse was easy to build once you understood the instructions. Lastly, I recommend the windows that open with temperatures for sure.
