The Glory is a tall, professional-grade greenhouse with a classic, house-like design. This greenhouse is as strong as they come with a powder-coated aluminum frame and 10mm thick polycarbonate panels.

The Glory stands tall with sidewalls over 6 feet tall and a peak of almost 9 feet. With its size, you’ll enjoy plenty of headroom and space to garden and trellis tall plants.

It features a heavy-duty, lockable door that's over 31 inches wide, allowing easy access for wheelchairs or wheelbarrows.

The Glory comes with a side louver window and a roof vent to allow proper airflow for the ideal temperature. It also features a rain gutter system that collects fresh rainwater for sustainable irrigation.

If you are a professional grower or a serious hobbyist, this is your greenhouse.

Why Palram?

Palram is one of the leading companies in the thermoplastic industry.

Palram greenhouses are made of polycarbonate panels designed to withstand extreme weather conditions due to their strength and flexibility. They do not shatter and are safer than glass. This feature is especially important in a domestic environment and the vicinity of children and the elderly.

Polycarbonate panels are low weight ( less than 1kg), making the greenhouse easy to deliver, handle, assemble and also relocate. For instance, an assembled 6×8 harmony greenhouse weighs less than 45kg.

Polycarbonate completely shields from the harmful effects of UV radiation and protects everything inside the greenhouse: people, plants, pots, tools among others.

No, it is not an option to get doors on both ends.
The greenhouses do not come with a floor or base.
Yes, the polycarbonate panels are high impact resistant and withstand hail.
The warranty for all our greenhouses is for at least 5 years, some for more. The crystal-clear single layer or twin-wall polycarbonate panels maintain their integrity, they do not discolor, opacify, fracture, or shatter over time.
Each wall section can carry up to 44 lbs. at most – an entire wall would depend upon the greenhouse’s size.

It can be anchored to a foundation, depending on the greenhouse, some have compatible holes at the bottom of the greenhouse base, and some have their own integrated anchoring.

Yes, the greenhouse can be anchored to a concrete slab. It can be anchored directly to the ground using ground stakes (ground stakes are not supplied with the greenhouse kits).

Firmly connect the product to a level surface immediately after completion of the assembly. Anchoring this product to the ground is essential to its stability and rigidity. It is required to complete this stage in order for your warranty to be valid.

The Palram Greenhouse can be used year-round, there are several factors to consider. The two main factors are weather and plants.

What are the plants you want to grow and how much heat or cold can they handle? No matter where you live, greenhouses can be 20-40 degrees hotter inside during the day and at night they will be the same temperature as the outdoors. This is without any supplemental heating or cooling.

Depending on where you live, heating and/or cooling your greenhouse can make the difference. If you need to heat or cool your greenhouse in extreme weather conditions, you may want to consider a twin-wall greenhouse such as the Palram Glory Greenhouse which has a 10mm polycarbonate covering.

It is not possible to add an additional door.
Greenhouse accessories can help you make the most of your greenhouse space by customizing it to your specific needs; making gardening more efficient, productive, and approachable. Clear floor room by using shelves, use additional vents and louvers with manual or automatic openers to stabilize heat and humidity levels. For a complete accessories listing please visit our Accessories page.
The stability and long-term service of a greenhouse relies heavily on the preparation of a firm foundation for placement and fixing. If you install a greenhouse on a ground with low moisture content it is highly recommended to use a ground cover or weed barrier, which will allow water to drain through the fabric while keeping weeds from growing.
