What a fantastic Greenhouse you supplied us. We requested a Twinwall Polycarbonate roof on our Shade house section instead of the aluminium shade panels.
This has been absolutely brilliant and enables us to grow plants that don’t like being wet all year round and when we have flowers they don’t get ruined by rain. Here a a few photos

If you are considering buying a Greenhouse it pays to do your research and ask the right questions such as...
Where is the Greenhouse made?
Is it manufactured locally or imported? Remember locally made Greenhouses are often better suited to local conditions (i.e. wind, sun, hail, snow, earthquakes etc…) while imported Greenhouses are often mass-produced at a very low cost from low-quality materials to provide a good profit margin for ‘the importers’.
What sort of guarantee does the Greenhouse have?
When you buy a Greenhouse, you want peace of mind that it will last for many years. Ask details of any guarantees, and ensure the glazing is covered by the guarantee. Ask how long the company you are purchasing from has been in business and consider the likelihood of them staying in business further down the track for after sales support and fulfillment of any guarantees.
Do they specialise in Greenhouses?
It is always better to buy from a company that specialises in Greenhouses than a general importer/merchant trader. The knowledge base within a specialist company will be greater, which will help when choosing the right Greenhouse to suit your needs and with after sales support.
What size Greenhouse will best suit my needs?
‘Try before you buy’, or ‘test-drive’ a Greenhouse. When you attempt to visualise the size of a Greenhouse from dimensions you’ve read, compared to stepping inside a Greenhouse, the latter will always prevail. If you are considering buying a Greenhouse, walking inside varying sizes of Greenhouse will help establish the right size for you. Spend some time planning the rough layout of your ideal Greenhouse (including fully grown plants with appropriate dimensions). The width and length are a major factor in determining the most suitable size, but you might wish to also consider the height of the Greenhouse (usually at the eave) to ensure it will accommodate the height of the plants you plan on growing.

What glazing will best suit my conditions?
Glass, polycarbonate, flexible plastic film (polyethylene)… there are various glazing options available. All of them have their advantages and disadvantages. For example glass looks great and lasts the longest, but doesn't perform as well as polycarbonate in the colder, ‘frost-prone’ regions. Polycarbonate lasts well (16-20+ years provided it’s a premium grade from a trusted manufacturer) and provides superior growing results, thermal efficiency and frost protection, while poly-ethylene offers a lower-cost covering option per square meter while still lasting approximately 3-5 years before replacement is required. Most importantly it is worth noting whichever option you decide, a high-quality glazing product from a reputable manufacturer will serve you better (in both performance and longevity) than cheap ‘non-branded’ glazing that usually only lasts a fraction of what it should.

Does the Greenhouse come with good assembly instructions?
Don’t take their word for it, ask to see the instructions! The assembly instructions should be written in plain English with a clear step-by-step process. You should be able to erect the Greenhouse without any specialised skills, tools or equipment. If you can’t understand the instructions, or would rather not attempt the assembly yourself, ask if they provide an assembly service in your area.
Replacement parts, accessories and local support… Are they available?
Just in case the unimaginable happens and you require a replacement part or something doesn’t fit as you think it should, will the company you purchased from be able to assist? Often additional vents, shade-covers, shelving etc… are required further down the track once you’ve got your greenhouse up and running. Are these accessories available, and if so, can they be retro-fitted to an already erected Greenhouse?
Our best top tips...
There are many cheap, poor quality Greenhouses imported into New Zealand every year and most of them don’t last more than 18 months. Make an informed decision based on over-all value for money.

Glass vs. Polycarbonate vs. Plastic Film
There is a range of different glazing options for greenhouses and to be honest they all have advantages and disadvantages when compared. The right glazing for your greenhouse will be determined by your requirements, personal preferences, climate and budget.

How to Layout your Greenhouse?
The obvious growing seasons for home gardeners are spring and summer, but autumn and winter are great for growing if you employ a few tricks. First, plant and sow vegetables that are clearly labelled as suitable for the season. Check the zone and sowing time on the seed packets.
Although some state late summer sowing times, you can challenge that to a degree. Generally, the label refers to direct sowing in the ground. If you change the growing conditions, and sow in a warm spot, or in a pot, you will likely have success.
Choose the sunniest, best drained spot in your garden, ideally in a raised bed. Grow veges on the north side of a masonry wall, which will store and radiate heat, or sow seed under a cloche or larger growing tunnel if you have space.
A growing tunnel or small glasshouse are cost effective options to ensure you can harvest veges right through the year, and get seedlings started in early spring to get a jump on your summer garden. A glasshouse is also a pleasant place to potter in on a rainy day.
Glasshouses are attractive additions to backyards if there's room. Vintage cold frames, cloches, glasshouses and growing frames ooze old-world charm. For inspiration, check out some of the English and American websites offering these wares. In this part of the world, the closest we can get to this look without breaking the bank is by integrating recycled timber or steel crate windows into a DIY design.
There are good-looking locally made options, but these tend to be of pragmatic rather than decorative design. Commercial glasshouse manufacturers offer models in toughened glass or polycarbonate material, with frames usually of easy-care aluminium.
It is relatively easy to build a simple DIY grow house. Attach thick polythene to a timber frame with gaffer tape and staples. Ensure you allow for ventilation by opening the doors or rolling up the sides on hot days. For a more permanent structure, use recycled windows or French doors with small panes. For safety, tape clear gaffer tape or safety film across the pane in case of breakages.
I've previously used timber-framed windows for a cold frame. Eventually, the glass was broken by an errant tennis ball. Ensure you install latches to prevent breakages in wind gusts. Replace broken glass (use gloves, and wrap carefully) with tough pieces of polycarbonate, or thick polythene, which is available in lengths cut to measure at hardware stores or in bulk from greenhouse manufacturers.
Avoid using opaque film in a spot that doesn't get full sun all day in winter. Days are shorter and there is less available light, so there's no need to reduce light further. Opaque greenhouses are mainly for seedling propagation. Plants grown to maturity in an opaque house may end up leggy, particularly in winter.
Choose clear plastic for winter crops, and ensure there is daytime ventilation to prevent plants overheating. Wean hardier types out of the cloche once they are established, but ensure they are sheltered from cold wind.
To warm things up without a cloche or glasshouse you can modify the soil by keeping it aerated. Cold, heavy soil is less than ideal for sowing seed. Dig a trench and introduce lighter soil from another spot in the garden, then sow or plant, or add a few inches of organic seed-raising mix to the trench. I do this when sowing delicate seed such as carrot.
Protect new plants and seedlings from wind chill - erect a small wind break if need be. This will ensure you've given your seedlings a good start in life, for a productive cool-season garden.
Winter kitchen garden
• Plant Chinese greens, mizuna, broccoli, kale, cabbage, and cauliflower. Plant leafy greens such as perpetual spinach, endive, chicory, silver beet. Sow rocket, corn salad, winter mesclun salad, and miner's lettuce. Plant hardy herbs such as coriander, Italian parsley and chives.
• Peas and broad beans are easy to grow. Peas need around 1.5m of chicken wire to hook their tendrils into as they climb. Cover with bird net and sprinkle pet-friendly Quash snail bait around your plants.
• Seed garlic is at garden centres now. Or, buy cheap organic garlic that has already begun sprouting from the grocer. Non-organic garlic is usually sprayed to prevent sprouting. Plant leek and onion seedlings. Sow carrot and beetroot (in rotation after heavy-feeding brassicas) in a well-drained, sunny spot for spring/early summer harvest. Soak beetroot seed overnight before sowing.
• Divide strawberry plants and plant now for a healthy harvest later in the year.
• Before sowing or planting, incorporate organic fertilisers such as well rotted manure/sheep pellets, lime or dolomite and basalt rock dust (found in Environmental Fertiliser's Nature's Organic Fertiliser, or Agrissential's Rok Solid).
• Seaweed is plentiful this time of year on the east coast, washed up in great piles after storms and it makes a great addition chopped into the soil.
