Halls ICON 6 6x4 Greenhouse 4mm Polycarbonate - Green HR01013

The Halls ICON 6 6x4 Greenhouse with 4mm polycarbonate glazing offers a compact, well-proportioned growing space that fits comfortably into smaller gardens without limiting what you can grow.

When space is limited, the ICON 6 6x4 greenhouse offers the perfect balance of practicality and reliability. Ideal for smaller gardens or those downsizing, it provides enough room to grow seedlings, protect young plants, and extend the season.

The 4mm twin-wall polycarbonate glazing diffuses sunlight to reduce scorching, retains warmth evenly, and resists knocks and unpredictable weather. Its powder-coated green aluminium frame resists rust and corrosion while blending naturally into your garden. The compact 6x4 footprint gives practical growing space without overwhelming your outdoor area.

A single roof vent provides effective, easy-to-manage ventilation, keeping internal temperatures under control and your plants healthy. With the ICON 6, you get a durable, space-saving greenhouse that’s straightforward, safe, and built to last.

Why ventilation matters

Plants thrive in environments where air can circulate gently rather than sit stagnant, supporting pollination, transpiration, and overall plant health. Good airflow also helps reduce condensation on the polycarbonate panels, maintaining clearer light transmission and more consistent growing conditions. The roof vent is easy to operate manually, allowing it to be opened wider on hot days and closed securely when extra warmth is needed. While the greenhouse features one dedicated vent, the smooth-action sliding door also plays a practical role in ventilation, improving airflow when opened during milder conditions.

Integrated gutters add everyday practicality, by managing rainwater run-off and supporting water collection, the area around the greenhouse remains tidy and easy to work in. With its reinforced aluminium structure and sensible proportions, this small polycarbonate greenhouse feels stable and reassuring once in place, particularly when paired with the recommended galvanised steel base.

What makes the ICON 6 easier and safer to use day to day

4mm polycarbonate glazing for added safety and insulation

The 4mm twin-wall polycarbonate panels are lightweight, virtually unbreakable, and far more forgiving than glass, making them ideal for everyday use in family gardens or exposed locations. The twin-wall construction also improves insulation, helping to maintain steadier temperatures while diffusing light to reduce plant scorch.

Higher eaves for better comfort and airflow

The increased eaves height creates a more open internal feel, encourages natural air circulation, and makes routine tasks such as watering, potting, and plant care more comfortable within a compact greenhouse.

Powder-coated for lasting protection

As well as offering a stylish modern finish, the powder-coat to the aluminium frame provides an extra layer of protection against corrosion and wear, helping your greenhouse stay strong and looking great for years with minimal maintenance.

Low-threshold sliding door for easier access

The smooth-action sliding door preserves valuable internal space and allows straightforward access with tools, trays, and compost, reducing strain during frequent use.

Stable aluminium frame with reduced maintenance

The rust-resistant aluminium frame is designed to withstand year-round weather without the upkeep required by timber alternatives, keeping the greenhouse dependable and easy to manage over time.

Secure polycarbonate panels with reduced movement and condensation

Polycarbonate panels are held securely in place to minimise movement in windy conditions, while their structure helps reduce condensation dripping compared to single-pane glazing, contributing to a quieter and cleaner growing environment.

Integrated guttering for controlled rainwater collection

Built-in gutters manage rainwater run-off effectively and are ready for connection to optional 40 mm downpipes, making rainwater harvesting simple and practical.

Optional add-ons to create a complete setup from the start

The Halls ICON 6 can be customised at the point of purchase with practical additions such as a waterbutt and stand, downpipe kit, and louvre kit for improved ventilation. Decorative traditional greenhouse cresting and protective capping are also available to enhance appearance and durability, allowing you to tailor the greenhouse to your gardening style. Additions can only be purchased at the same time as ordering the greenhouse.

Frequently asked questions

Do I need a base for my greenhouse?

In most cases, yes, a base is strongly recommended. A purpose-made greenhouse base makes installation far easier, ensures the structure sits level, and provides long-term stability. This helps protect both the frame and the glazing over time.

If your greenhouse is being installed onto an existing solid surface such as a concrete pad, brick base, or wall-mounted foundation, you may not require a separate steel base. However, where no suitable foundation already exists, a proper base is the safest and most straightforward option.

Occasionally, bases may be included as part of a special offer. If that applies, the option can simply be selected at zero cost when ordering.

Do I need professional installation?

All greenhouses are supplied with full instructions and many customers do successfully install them themselves. However, installation does require time, careful preparation, and suitable weather conditions. Many customers choose professional installation for added convenience and peace of mind. If you do opt for installation for your Icon 6 greenhouse, it is essential that the area is fully prepared ahead of time. This means the ground must be level, clear of debris, and easily accessible for the installation team.
