Frequently Asked Questions
What to Consider When Choosing a Garden Greenhouse?
Size and footprint matter. Measure your available space and think about how you'll access the inside. A larger footprint means more storage space, more bench room, and better airflow, but also requires a sturdy base and solid anchoring in windy UK gardens.
Materials and glazing impact light, insulation, and maintenance. Polycarbonate panels are lighter, shatter-resistant, and provide good insulation, while glass offers excellent clarity and lasting aesthetics. Consider a hybrid approach or a polycarbonate-glass combo for best results.
Ventilation and climate control are essential. Look for adjustable vents, louvres, and doors that facilitate airflow to prevent mold and heat buildup. For cooler climates, the option to add a heater or heat mats can extend the growing season responsibly.
Foundation and base systems matter for stability and ease of installation. Some kits include a simple base frame, while others benefit from a concrete or timber foundation. A solid base prevents damp from seeping inside and keeps panels aligned over time.
Shelving and staging improve organization. Adjustable shelves, trough bays, and potting benches help you maximize space and keep tools and seedlings within reach, reducing clutter and improving workflow.
What Are the Most Popular Types of Garden Greenhouses?
Lean-to greenhouses share a wall with a building, offering compact growth space that’s ideal for patios or limited gardens. Freestanding greenhouses provide expansive layouts with more headroom and wider door access for easy movement of trays and pots.
Mini or hobby greenhouses are perfect for herbs, seedlings, and small hobbyists, often featuring modular designs that can be expanded over time. Arch or curved-top models deliver a classic aesthetic while still delivering great light transmission and easy maintenance.
Glasshouses emphasize clarity and premium look, best for dedicated gardeners prioritizing maximum light. Polycarbonate greenhouses balance weight, safety, and insulation, making them popular for year-round use in varied climates.
How to Maintain a Garden Greenhouse?
Regular cleaning helps prevent algae and mold buildup. Use soft brushes and mild soapy water for panels and frames, avoiding harsh chemicals that could degrade seals or coatings. Check seals around panels periodically and replace worn gaskets to maintain insulation.
Ventilation is key to healthy plants. Ensure vents operate smoothly and clean any dust from louvers to maintain airflow. Consider installing an automatic vent opener for consistent temperature control without manual intervention.
Climate control supports thriving growth. Depending on your setup, you may add a small heater, a ventilation fan, or a shade cloth to manage sun exposure on hot days. Pair these with a simple irrigation system or drip lines to maintain soil moisture precisely.
Maintenance also includes base and frame care. Check for rust on metal parts, tighten bolts, and treat timber frames with a suitable sealant to extend lifespan. With proper care, your garden greenhouse can deliver seasons of productive growth.
Keep your greenhouse organized with sturdy benches, potting stations, and a reliable irrigation setup. Our selection includes greenhouse kit options that bring together framing, panels, and shelving to streamline assembly and use.
What Are the Best Accessories for a Garden Greenhouse?
Consider adding shelves and staging for efficient space use, a simple thermometer/hygrometer combo to monitor conditions, and a watering system tailored to your crops. Shade netting helps prevent scorching on sunny days, while a pest exclusion net can reduce insect pressure without chemicals.
Automatic venting, door mats, and weatherproof trimming can enhance usability and longevity. Lighting for winter or early-spring growth can also extend your growing window, especially when paired with energy-efficient LED grow lights.
What Size Garden Greenhouse Do I Need?
Choosing the right size depends on space, budget, and intended crops. For herbs and a few trays, a compact 6x6 ft or 6x8 ft unit may be sufficient. If you plan tomatoes, cucumbers, peppers, and more tomatoes, a larger footprint like 8x10 ft or bigger provides room for shelves, benches, and working space while maintaining good airflow around plants.
Are Polycarbonate Panels Better Than Glass?
Polycarbonate panels are lighter, more impact-resistant, and provide excellent insulation, helping to regulate temperatures with less energy. They’re typically less prone to cracking and are easier to handle during installation. Glass offers superior clarity and a premium look, but can be heavier, more expensive, and may require a more robust frame and better sealing for insulation. Depending on climate and budget, many gardeners choose polycarbonate for year-round use and light transmission, with tempered glass as a premium option in dry, sheltered spots.
Do I Need a Foundation for a Garden Greenhouse?
A solid foundation stabilizes the structure, helps with drainage, and keeps panels aligned over time. Depending on the model, some kits include raised bases or anchor systems designed for concrete slabs, paving, or timber decking. In areas with strong winds, a proper foundation reduces movement and extends the life of your greenhouse. If you’re unsure, choose a kit that includes easy-to-install base frames or consult a professional for a basic foundation plan.
How Do I Control Temperature and Humidity Inside a Greenhouse?
Ventilation is the first line of defense against overheating. Openable ridge and side vents, moveable doors, and automated vent openers help maintain steady temperatures. For humidity control, ensure adequate air circulation and consider a simple misting system or humidistat-enabled humidifier during damp periods. A heater or heat mats may be appropriate for cooler climates, but choose energy-efficient models and insulate panels where possible to minimize costs.
What Extras Should I Consider for a Garden Greenhouse?
Look for adjustable shelves, potting benches, and irrigation solutions like drip lines or hose-end timers to automate watering. Shade cloth or external blinds help regulate sun exposure on hot days, while insect screens protect crops without harsh chemicals. If you intend to overwinter plants, plan for heat sources, insulation, and a robust sealing system to maintain a stable environment. Finally, ensure the kit includes clear installation instructions, and consider customer reviews on ease of assembly and after-sales support.
