The Planta Sigma Urban was created for spirited gardeners working with compact urban and suburban spaces. This greenhouse is ideal for 3 or 4 season gardening, so you can harvest homegrown fruits and vegetables throughout the year. Our Sigma collection focuses on sturdy construction and spacious design, bringing heavy-duty greenhouse engineering right to your backyard.
The tough galvanized pipe frame is rust-resistant and built to last. It's strong enough to handle moderate to severe weather conditions, keeping your garden protected throughout the seasons.
The greenhouse comes with:
- two doors
- two manual windows
- the option to install multiple windows.
This greenhouse is particularly comfortable to work in throughout the day due to the end-to-end ventilation and the unique 7ft roof height.
- TGTess G.Verified BuyerRated 5 stars10 months agoThe growing season was significantly extended
We grow greens and medicinal herbs in our greenhouse, and the growing season was significantly extended and more forgiving of a late start. It is a sleek and simple design. Our buying experience from Planta was great. The assembly process was miserable, but once built, it was a joy to use.
- MBMichaelle B.Verified BuyerRated 5 stars10 months agoEvery time I look out into my garden, this greenhouse still makes me smile
I grow tomatoes, cucumbers, peppers, and hanging baskets of strawberries in my greenhouse. I was able to plant in April and had greens growing until Christmas. I just love the smell inside the greenhouse :-)
Our experience buying from Planta was excellent! We recently bought an extension and there were some pieces missing. One phone call and they were on their way.
This is our second winter, and we haven’t had much snow, but what we have had has not affected the greenhouse at all. I’m very happy with the product and I’m very happy with the service. We did have some problems putting it up, but that’s because we were brand new to this.
Every time I look out into my garden, this greenhouse still makes me smile.
- ESEric S.Verified BuyerRated 5 stars11 months agoWe have a short season, so now we get an early start
We installed our greenhouse in 2021 & grow vegetables. We have a short season, so now we can get an early start. We enjoy hanging out inside of the greenhouse on those cold spring mornings. We had a great experience purchasing from Planta & if someone else is considering purchasing we’d say just DO IT!!
- CFChet F.Verified BuyerRated 5 stars11 months agoIt will extend my growing season by several months
I installed my greenhouse in 2021, and will store my Fig trees for the winter. In the spring I will use the greenhouse for my starter plants and in the fall I plan to use the greenhouse to extend the season for my container trees and plants. I’m sure it will extend my growing season by several months. It will be used as another tool to expand my gardening and fig tree growing experience. It will also expand my growing season. I am excited to start my greenhouse experience this spring.
My experience purchasing from Planta was easy and I was able to pay with PayPal. It was delivered to a trucking company 4 miles from my house for pick up and easily fit into my pickup truck. I had a friend help me unload the boxes to my backyard. Nick and Dave at the Planta office were always available when I needed to call for building instruction help.
The reason I went with a Planta Greenhouse was because it had two openings to enter into the greenhouse. I have a garden at one end of the greenhouse and a small fig orchard at the other end of the greenhouse. Plus, when I store trees, plants, or other items in the greenhouse, I'll have easier access to these items with the use of two doors.
To someone considering purchasing the greenhouse, I’d say that when building the greenhouse, have another person to help. I used a neighbors 10'x20' tent with no side covers, two sets of saw horses, and two sheets of plywood to set all boxes on to help with assembly. It took 12 to 14 days or about 36…
- JKJenna K.Verified BuyerRated 5 stars11 months agoI’ve been able to keep my summer flowers alive through the winter
I installed my Planta Greenhouse in 2021 & keep my summer flower pots, ivy, geraniums, herb pots, kale, tomatoes, and lavender. I’ve been able to keep my summer flowers alive through the winter as well as my hardier herbs.
It was an easy experience buying from Planta. My favorite thing about this greenhouse is that it is a good size and is very sturdy but it is a huge pain to put together.
