    Costumer Service

    Bought Sima 2021 Euro a couple of years back. Got it assembled last year and finally got auto vents installed this spring. One vent cyl did not function, it would not collapse. I got in contact with Murad at Costumer Service and he assured me that even though the warranty had expired they would send along a replacement. Logistic Coordinator Paulette followed up and new cyl arrived and works great. Excellent service . Finishing the install of a bench and drip system. Looking forward to great growing results.

    Turning It Into a 4-Season Greenhouse

    We grow a variety of herbs, tomatoes, several types of peppers, peas and beans, onions, garlic, mint, starters, and squash plants. It’s been a learning experience, but the greenhouse is helping us extend our growing season. Last year, during a grasshopper infestation, we had to transplant surviving outdoor plants into the greenhouse, and it provided the protection we needed. We’re now working on converting it into a 4-season greenhouse.

    Customer service was great and the product itself has performed well. We purchased the sunshade, which made a big difference. We also installed a trellis for vining plants and are currently working on setting up a heating and cooling system, along with purchasing greenhouse shelving.

    What we appreciate most is the protection it provides from critters and the elements, along with its spacious design—perfect for raised beds. Our students are about to help clean it out and get started on early spring planting. If we had the funding, we would install another one. As a non-profit farm running a school program, we’re currently applying for a grant to cover electrical installation so we can move toward full 4-season use.

    A Beautiful Greenhouse for My Wife

    I installed our first greenhouse, a Sigma model, in late fall of 2024. While we haven’t started growing yet, we’re just now getting ready to use it. My wife plans to grow vegetables, flowers, herbs, and microgreens. We’re expecting earlier seedling starts and a longer growing season overall.

    Buying from Planta was very easy. I did a lot of research beforehand and chose Planta for its combination of value and quality. Customer service has been great—a real person answers the phone! I called once with pre-purchase questions and twice more during assembly. Each time, my questions were answered clearly and promptly.

    We placed the greenhouse on the east side of our barn to help protect it from strong summer storm winds. I poured a cement slab with a 4" curb and anchored two 2"x4" treated boards on top, giving the greenhouse an extra 7" of height. I also installed a lateral 5" drain in the floor to help with water flow.

    My favorite thing about this greenhouse? It's a thing of beauty—and I bought it for my wife, who has always dreamed of having one. We’re both very happy with it and would highly recommend it. The combination of video guides, printed instructions, and the BILT app made installation easier than you’d think.

    A Warm Winter Garden

    We installed our Planta Greenhouse in 2024, and it’s already made a huge difference in our gardening experience. This was our first greenhouse, and it allowed us to start the growing season much earlier than usual. Even in winter, the greenhouse stays warm enough to comfortably work inside on sunny days—something I never expected to enjoy so much. I was even able to harvest cucumbers into mid-October!

    Inside, we’ve grown tomatoes, cucumbers, basil, and a variety of other herbs. To optimize the space, we built a solid wood foundation with raised garden beds and a concrete walkway between them. Gravel bedding and proper drainage around the structure have made it both functional and low-maintenance.

    Buying the greenhouse from Planta was straightforward. We took advantage of a Christmas discount, which inspired us to make the purchase sooner than planned. Delivery was on time, and although installation was a bit time-consuming (as expected for a first-timer), the process went smoothly. I’m genuinely impressed with the quality and performance of this greenhouse—and I’m really enjoying it!

    3 Sigma Greenhouses Later We Keep Choosing Planta

    After moving twice in five years, we've now installed our third Planta greenhouse—this time a 26-foot Sigma model alongside extra polycarbonate panels, which we used to create a custom lean-to greenhouse against our garage. With each build, we’ve refined our setup process, learning how to make installation smoother and more efficient every time.

    Our large greenhouse is dedicated to cabbages, broccoli, cauliflower, leeks, celeriac, and even a couple of grape varieties, with netting on the doors to help keep cabbage moths out. In our new lean-to space, we’re planning to grow tomatoes, peppers, squash, pumpkins, and cucumbers. We like to use grow bags for flexibility and continue to plant staples like potatoes, onions, and beans outdoors. Even our chicken coops benefit from leftover polycarbonate panels—adding natural light while keeping them warm and dry.

    The Sigma greenhouse has truly improved our gardening experience. It’s helped us extend our growing season and grow varieties that normally wouldn’t thrive in our climate. Planta’s greenhouses are incredibly sturdy—ours held up through heavy snowfalls, and after experiencing some damage from Hurricane Fiona, we added L-brackets and longer screws for extra reinforcement. These little adjustments have made a big difference, especially for older hands during assembly.

    Ordering from Planta is always a breeze. Their quality is unmatched, and the support team has consistently provided excellent service. That’s why we’ve returned…

FAQs

Gyvenamieji šiltnamiai

Ar abiejuose šiltnamio galuose yra durys?

Yes! All of our Sungrow models come with manual doors and a manual window above the door on both ends of the greenhouse.

Ar turite liesų šiltnamių?

Unfortunately, we do not have any lean-to greenhouses available at this time.

Ar gaminate nestandartinio dydžio šiltnamius?

All of our products come pre-packaged by the manufacturer and can only be customized in length (2m extension). However, the height of the greenhouse can also be increased if placed on a base (up to 1.5m above the ground).

Kaip šiltnamis tvirtinamas prie žemės ?

Every greenhouse kit comes with optional legs that can be dug directly into the ground. The amount of legs included depends on the greenhouse size.

Iš ko pagamintas rėmas?

The greenhouse frame is made out of heavy-duty galvanized steel.

Kokios polikarbonato plokštės naudojamos gyvenamiesiems šiltnamiams?

We use 6mm heavy-duty, double-walled polycarbonate panels with a UV-protected outside layer for our Residential Greenhouses.

Kokio tipo pagrindas/pamatai man tinkamiausi?

There are several different types of greenhouse bases, information, and pictures posted by our customers on our Customer Stories page and our Planta Facebook page. Additionally, you can learn more about "Types of Greenhouse Bases - With Pros & Cons of Each" on our blog.

DUK Sigma ventiliacijos langas

Ar vėliau galiu pridėti langus savo šiltnamiui?

Roof ventilation windows work as an add-on and can be installed only once the greenhouse installation is complete. Windows can be added later as well.

Kiek stogo vėdinimo langų rekomenduojama šiltnamiui?

It is strongly recommended to go with an even amount of roof ventilation windows. This is so you can place at least one on either side of the greenhouse. The amount of windows required depends on the greenhouse size, the climate you are in, and the types of plants that will be grown inside the greenhouse.

DUK Sigma automatinis vėdinimo langas

Kaip veikia automatinio vėdinimo langai?

Our Automatic Ventilation Windows do not require any batteries or electricity. A heat-activated mechanism will open/close the window once a certain temperature is reached.

Kokia yra automatinių langų ? atidarymo ir maksimali atidarymo temperatūra

The opening temperature is between 17 °C and 25°C, while the maximum opening is at 30 °C.

Sigma šiltnamiai

Kokia yra sniego apkrova ir atsparumas vėjui Sigma modeliuose?

Sigma models can hold a snow load weight of 160 kg / m2 or 91cm of fresh snow on top of the greenhouse. The wind resistance is 100km/h.

Sigma įrengimas

Tinkinimo parinktys

Ar galiu pridėti savo orlaides, ventiliatorius, šildytuvus ir šviesas?

Of course! The polycarbonate is very easy to work with, and the galvanized steel frame is strong enough to support any additional accessories.

Ar galiu gauti ilgesnį šiltnamį?

Most of our residential and commercial greenhouses are extendable up to 30 metres. Learn more about our extension kits for both the Sungrow and Sigma models.

Kaip galiu pritaikyti savo šiltnamį?

The customization possibilities are truly endless with a Planta Greenhouse. To help you get started, take a look through “16 Ways to Supercharge Your Greenhouse” on our blog.

Ar pakabinami augalai, šildytuvai ir hamakai yra saugūs nuo mano šiltnamio rėmo? Kiek svorio jis atlaiko nepažeidžiant garantijos?

It is safe to hang plants and accessories on a Sungrow greenhouse since each internal reinforcement arch can withstand up to 45.3 Kg. On the Sigma series, you can pre-drill the holes on the framing and hang small things. We would not suggest hanging anything heavier than 2.2 – 4.5 Kg per arch.

Ar galiu šildyti šiltnamį laužavietėmis ar panašiai?

You can use any heating source inside, like electricity, gas, propane, and even wood. It may be tricky to heat with wood, as you want to ensure that you keep the stove/pit away from the panels to prevent them from melting or burning if they are too close to the fire source. In this case, the customers ideally would want to come up with an exhaust system, making sure it’s not in contact with the panels, for being a flammable material.
