NOVA greenhouses – practical polycarbonate greenhouses for everyday growing

NOVA greenhouses are a practical choice for gardeners who want to grow vegetables, herbs and other plants in a protected environment without moving into the heavier reinforced greenhouse segment.

The range combines galvanised steel frames with lightweight 4 mm polycarbonate panels and is available in different sizes to suit anything from smaller gardens to more ambitious growing plans. A NOVA greenhouse can help you start seedlings earlier in spring, create better conditions for heat-loving crops during summer and continue growing selected plants later into autumn.

For many gardeners, this makes NOVA a straightforward and affordable way to extend the growing season and enjoy more home-grown produce from the garden.

What is a NOVA greenhouse?

A NOVA greenhouse is a polycarbonate greenhouse designed for normal seasonal garden use.

The frame is made from galvanised steel, while the transparent panels are made from 4 mm polycarbonate. This combination provides a practical balance between strength, low weight and everyday usability.

Polycarbonate is well suited to greenhouse construction because it is considerably more impact-resistant than traditional glass and easier to handle during assembly. At the same time, it allows plenty of daylight into the greenhouse, helping create the conditions plants need for healthy growth.

NOVA is therefore a good option for gardeners looking for a functional greenhouse without the weight and fragility associated with glass panels.

What can you grow in a NOVA greenhouse?

A greenhouse gives you more control over the growing environment than an open garden bed.

NOVA greenhouses are well suited to many common greenhouse crops, including:

• tomatoes
• cucumbers
• chillies and peppers
• herbs
• lettuce and other leafy vegetables
• seedlings and young plants
• selected flowers and ornamental plants

The enclosed space provides shelter from wind and rain and can create warmer conditions than those outside. This is particularly useful for heat-loving crops that may struggle during cool or unsettled summers.

A greenhouse also gives you a protected place to raise young plants before moving them into beds, containers or other parts of the garden.

Extend the growing season from spring into autumn

One of the main reasons for choosing a greenhouse is the opportunity to make more of the growing season.

In early spring, the greenhouse can provide a more protected environment for seedlings and young plants. During summer, it creates favourable conditions for crops such as tomatoes, cucumbers and peppers. As temperatures begin to fall in autumn, the greenhouse can continue to shelter plants after outdoor conditions become less suitable.

The exact growing season will always depend on local temperatures, daylight, ventilation and the plants you choose.

A standard NOVA greenhouse is not automatically frost-free or heated during winter. If you want to grow through colder periods, additional measures such as insulation, frost protection, heating or artificial lighting may be required.

Why choose polycarbonate instead of glass?

Polycarbonate offers several practical advantages for everyday greenhouse use.

The panels are lightweight, making them easier to handle during installation, and they are less vulnerable to impact than conventional greenhouse glass. This can be particularly useful in gardens where falling branches, children, pets or general activity around the greenhouse may otherwise increase the risk of breakage.

Polycarbonate also requires relatively little maintenance. It does not provide exactly the same appearance or transparency as traditional glass, but for many gardeners the combination of durability, low weight and practical handling makes it an attractive alternative.

The 4 mm panels used in NOVA greenhouses allow daylight into the structure while providing a protected growing environment for your plants.

Galvanised steel frame for a practical garden greenhouse

The galvanised steel frame forms the supporting structure of the greenhouse.

Galvanising helps protect the steel against corrosion and makes the frame suitable for long-term outdoor use when the greenhouse is assembled and maintained correctly.

The relatively simple construction also helps make NOVA accessible to gardeners who want a greenhouse they can assemble themselves.

As with any greenhouse, correct assembly is important. The frame and panels should be fitted according to the instructions, and the greenhouse should stand square and level to ensure that doors, panels and structural components function as intended.

Choose the right NOVA greenhouse size

The right greenhouse size depends on more than the amount of available garden space.

Consider what you want to grow, how many plants you expect to have and whether you need room for shelves, pots, pathways or working space.

A smaller greenhouse may be ideal if you mainly want to grow herbs, seedlings and a few tomato or cucumber plants. A larger model gives you more flexibility if you want to grow several crops at the same time or need space to move comfortably between plants.

Before choosing a greenhouse, it is worth marking out the dimensions in the garden. This makes it easier to judge both the footprint and the space needed around the greenhouse for access, maintenance and opening doors.

A stable and level base is essential

A greenhouse performs best when it is installed on a stable and level foundation.

The exact solution will depend on the greenhouse and your garden, but the important point is that the base supports the structure evenly and prevents movement or distortion.

Possible solutions may include a prepared foundation, paving or another stable surface suitable for the specific model.

Good drainage around the greenhouse is also important. Avoid placing it in an area where water regularly collects, as persistent moisture around the base can create unnecessary problems over time.

Always follow the installation instructions and anchoring recommendations supplied with the individual greenhouse.

Position the greenhouse for light and practical access

Location plays an important role in how well a greenhouse works.

Choose a position where the greenhouse receives sufficient daylight during the growing season and is not unnecessarily shaded by buildings, dense hedges or large trees.

At the same time, consider exposure to wind. A sheltered position can reduce the strain on the structure and create more stable growing conditions inside.

You should also think about everyday access. Placing the greenhouse close to a water source, garden path or storage area can make watering, harvesting and maintenance considerably easier.

Ventilation is important during warm weather

A greenhouse can become very warm on sunny days, even when outdoor temperatures are moderate.

Good ventilation helps regulate temperature and humidity and reduces the risk of an excessively hot or humid environment. Doors and any ventilation openings should therefore be used actively during warm periods.

Plants also need appropriate watering and air circulation. How often you need to ventilate or water depends on the weather, the size of the greenhouse and the crops you are growing.

During particularly sunny periods, shading may also be useful for sensitive plants.

NOVA or a reinforced snow-proof greenhouse?

NOVA greenhouses are intended for normal seasonal greenhouse use and are a good choice for many ordinary garden conditions.

If you live in an exposed location or an area with regular heavy snowfall, strong winds or more demanding winter conditions, a reinforced greenhouse may be the better solution.

Strong NOVA and other snow-proof greenhouse models are designed with higher structural load capacities and stronger constructions specifically for these conditions.

A reinforced greenhouse should not be chosen on the basis of appearance alone. Compare the stated snow load, wind resistance, frame construction, panel thickness and dimensions of the individual model before deciding.

Likewise, a standard NOVA greenhouse should not be treated as a heavy-duty winter structure unless the specifications for the individual model explicitly support that use.

Low-maintenance greenhouse for everyday gardening

NOVA greenhouses require relatively little maintenance, but regular care will help keep the greenhouse working well.

Keep panels reasonably clean so that daylight can enter the growing area, and check the structure periodically for loose components or damage. Leaves and debris should be removed from around the greenhouse, and doors and moving parts should be kept clear and functional.

Before colder weather, inspect the greenhouse and make sure that panels and frame components are correctly fitted.

If snow accumulates in your area, follow the instructions for the specific greenhouse and do not assume that a standard greenhouse can carry the same loads as a reinforced snow-rated model.

Who are NOVA greenhouses suitable for?

NOVA is particularly well suited to gardeners who want a practical greenhouse for seasonal cultivation and do not require the heavier construction of a reinforced snow-proof model.

It can be a good choice if you:

• want to start growing earlier in spring
• grow tomatoes, cucumbers, chillies or similar crops
• want to protect young plants from wind and rain
• prefer polycarbonate to fragile greenhouse glass
• want a greenhouse with relatively low maintenance
• need a choice of sizes for different garden layouts
• want a functional greenhouse for regular home gardening

The right model ultimately depends on your available space, local weather conditions and how extensively you plan to use the greenhouse.

Frequently asked questions about NOVA greenhouses

What are NOVA greenhouses made from?

NOVA greenhouses combine a galvanised steel frame with lightweight 4 mm polycarbonate panels. The combination provides a practical structure for normal seasonal greenhouse use.

Are polycarbonate greenhouses better than glass greenhouses?

They offer different advantages. Polycarbonate is lightweight, impact-resistant and easy to handle, while glass provides greater transparency and a more traditional greenhouse appearance. The best choice depends on your priorities and garden.

Can I use a NOVA greenhouse during winter?

The greenhouse can remain an outdoor structure through the seasons when installed and maintained according to the instructions, but a standard NOVA greenhouse is not automatically frost-free or designed for heavy snow loads. Winter growing may require insulation, heating or other protection.

Is a NOVA greenhouse suitable for areas with heavy snow?

If regular heavy snowfall or demanding winter weather is a major consideration, choose a reinforced Strong NOVA or another snow-proof greenhouse with a specified higher snow load capacity.

Do NOVA greenhouses need ventilation?

Yes. Ventilation is important for controlling heat and humidity, particularly during warm and sunny weather. Doors and available ventilation openings should be used according to the conditions.

Does the greenhouse need a foundation?

It should always stand on a stable, level base and be installed and anchored according to the instructions for the individual model. A well-prepared base helps the greenhouse remain square, stable and functional over time.
