Types of greenhouses

Best portable greenhouses for winter

Portable greenhouses are similar to starter greenhouses, but instead of being fixed structures they are temporary and mobile. They are covered with plastic instead of glass.

Benefits of a portable greenhouse:

  • Portable greenhouses for winter are ideal for those who can’t or don’t want to commit to building a permanent greenhouse (renters, for example).
  • You can move portable greenhouses, if necessary, and store them when not in use.
  • These greenhouses are quick and easy to assemble.
  • If you are on a limited budget, a portable greenhouse is an economical option.

Portable greenhouse disadvantages:

  • Portable greenhouses are not as effective at retaining heat as fixed models, so they will not extend the growing season as long.
  • These greenhouses are not as durable as traditional models. The cheaper ones may deteriorate after a couple of growing seasons.

Portable greenhouse prices:

  • Depending on the size and quality, you can pay anywhere from €50 to €200 for a portable greenhouse.

Starter greenhouses or glass greenhouse kits

Seedling greenhouses are small to medium-sized structures designed for planting and growing seeds until they can be transplanted into larger pots or outdoor beds. Starter greenhouses are set in place and protected with glass instead of plastic.

Benefits of a glass greenhouse:

  • The glass greenhouse kits for sale are perfect for gardeners who ultimately want to grow their plants outdoors, but need a place to start seeds before the risk of frost has passed.
  • If your yard or garden is not too large, these greenhouses take up less space than large grow greenhouses.
  • Starter greenhouses are often very versatile and can also be used as planters.

Glass greenhouse disadvantages:

  • This type of greenhouse may not be large enough to grow large plants.
  • Some seedling greenhouses may require professional installation.

Starter greenhouses prices:

  • Basic starter greenhouses cost between €300 and €700. Larger, custom-built models sell for thousands of euros.

Growing greenhouses

Growing greenhouses are large structures designed to grow plants, from seeds or seedlings to full-grown plants.

Benefits of a growing greenhouse:

  • If you want to grow fruits and vegetables year-round, a growing greenhouse is what you need.
  • Growing greenhouses are very versatile. They can be used to start seedlings, grow from seed to harvest, as an all-purpose potting shed, or a combination of all three of the above.
  • Most grow greenhouses come with a variety of shelving that can be adjusted to meet your needs.

Growing greenhouse disadvantages:

  • Unless you live in a very warm climate environment, you will need heating and lighting in your greenhouse for year-round use.
  • You will need a lot of space in your yard or garden to place this type of greenhouse.
  • You may need professional help to set up a growing greenhouse.
  • These greenhouses are quite expensive.

Growing greenhouse prices:

  • You can find grow greenhouses starting at around 2,000 euros. Large, high-end models cost more than 10,000 euros.

Mini greenhouses for sale

Mini greenhouses are small, portable models that are generally not large enough for one person to enter. They come with a number of removable shelves to maximize the available growing space.

Benefits of a Mini greenhouse:

  • Mini greenhouses are perfect for gardeners who want to start growing their plants a little earlier in the season, but aren’t concerned about growing them year-round.
  • Their compact size makes mini greenhouses a great option if you don’t have a lot of space.
  • Most of these greenhouses are extremely inexpensive.
  • These greenhouses are very easy to assemble, usually not requiring the use of tools.

Mini greenhouse disadvantages:

  • A mini greenhouse will probably be too small for the needs of gardeners who handle a large number of plants.
  • These types of greenhouses are not particularly stable.
  • Plastic covers can become brittle with the effect of UV rays after a year or two of use.

Mini greenhouse prices:

  • Most mini-greenhouses cost between €30 and €40.

How to choose a greenhouse

Greenhouse size

The size of the greenhouse you are going to buy should depend on your needs.

If you only want to plant and start a handful of plants to transplant outdoors later, a compact greenhouse between 1.2 x 1.8 meters and 1.8 x 2.4 meters should be sufficient. Keep in mind that increasing the size by just half a meter can give you a lot more usable space for a little more money.

If you have more serious gardening ambitions (producing vegetables all year round, for example), you should opt for a minimum of 2 x 4 meters. You can also find larger models, up to 5 x 6 meters.

Greenhouse shape

Most greenhouses are square or rectangular, although you can find some hexagonal or octagonal models. As a general rule, square and rectangular models are the most practical options. They make the best use of your patio space and are available in a wide range of dimensions.

Hexagonal and octagonal models can be attractive, but are less readily available, more expensive and more difficult to ventilate.

Frame Material

  • Aluminum: Durable, lightweight and inexpensive, aluminum is perhaps the most common choice of material for greenhouse frames. It can also be powder-coated in a very wide range of colors, so you can match it with other furniture or elements in your garden.
  • Wood: Those who want a more classic look often prefer a wood-framed greenhouse. Although they are undeniably attractive, they are not as durable as aluminum greenhouses and cost more.

Covering material or glazing

  • Horticultural glass: This is the most common material for starter and grow-in greenhouses. Horticultural glass is supplied in 40-square-centimeter panels that overlap where they are joined. Although relatively inexpensive, this glass is fragile and the joints are difficult to clean.
  • Safety glass: If you are on a budget, we recommend a greenhouse with toughened safety glass. This comes in larger panes, so there are no unsightly overlaps and difficult to clean. It is stronger than horticultural glass and less likely to break.
  • Polycarbonate: A new coating option for greenhouses is double-walled polycarbonate. It is strong, lightweight and extremely well insulated, so it retains a lot of heat. However, it doesn’t let in as much light as glass, so it’s not as good for plants that need a lot of sun.
  • PVC: Most mini greenhouses and portable greenhouses are protected with a PVC sheet. Although it is lightweight and flexible, it does not withstand UV radiation well and tends to degrade after a year or two due to weathering.

Greenhouse tips and tricks

  • Before you commit to buying a greenhouse, you should decide exactly where you are going to place it and make sure your greenhouse will fit there.
  • Orient your greenhouse properly. An east-west orientation will give your plants a little more light during the winter; a north-south orientation is better for summer crops. However, if your greenhouse is only half a meter longer than it is wide, its orientation won’t matter much.
  • Place your greenhouse away from trees. If you place it too close to trees, you will have to continually clear leaves from the roof.
  • Choose a well-leveled location for your greenhouse. The greenhouse needs a level base, so choose a flat area or make the site level.
  • Protect your greenhouse from wind. Even the best-built greenhouse is not immune to high winds. Place yours near a fence, wall or hedge to give it some degree of protection.
  • Place your greenhouse in a convenient location. If you have a large yard, you may not feel like going to the far corner to check on your plants before bedtime.

Greenhouse main problems and questions


Q. Will I need professional help to set up my greenhouse?

R. Some greenhouses require professional installation, especially those that need a proper foundation. Other models can be assembled fairly easily, either by yourself or with someone to help you. If you are unsure, the product specifications should help you decide.

Q. Should my greenhouse have clear or diffused glass?

R. Most greenhouses have clear glass because this allows most of the light to pass through, making it ideal for starting plants and growing them for later transplanting outside. However, if you want to grow vegetables continuously until they are harvested, you should consider diffused glazing. It provides more even light, which is better for helping plants through their entire growing cycle.

Q. Will I need heating in my greenhouse?

R. Although most people do not heat their greenhouses, you may want to install heating in your greenhouse if you intend to grow tropical plants or maintain them throughout the winter.

A brief history of gardening

The history of gardening is, in a not so roundabout way, the history of human civilization. Long before people took up writing instruments to record the stories of their lives, the archaeological record shows that mankind moved from being hunter-gatherers, foraging for food sources in nature, to the establishment of more permanent settlements. The dawn of civilization is defined by the development of: the domestication of formerly wild species for human consumption, including the cultivation of edible plants.

Apparently, in the grand scheme of things, it did not take humans long to discover the benefits of taking measures to protect and shelter their newly domesticated crops from elemental extremes. Evidence of flood and fire control can be found in artifacts from the early Neolithic period. And the practice of growing plants under cover dates back at least to the days of ancient Rome, when Emperor Tiberius enjoyed the fruits of a cucumber-like plant so much that his gardeners set up something like primitive greenhouses to grow them year-round. Using sheets of selenite, a transparent rock, they built structures to protect the plants from frost without blocking the sun.

During the Renaissance, the advent of new glassmaking techniques facilitated the construction of larger and more sophisticated glazed structures, and non-native plants brought from exotic places by explorers and traders were housed inside during the colder months. These early greenhouses were the showplaces of the botanical gardens they served. They were called orangeries, named for the large citrus trees that often spent the winter there, the most famous of which may be the one built at Versailles. Completed in 1686, the greenhouse at Versailles was not well planned in terms of ideal growing conditions; it faced northwest, let in very little sun, and had an inefficient coal furnace that alternately heated and froze the plants, many of which would barely survive until spring.

The abolition of tariffs on glass windows in the 19th century contributed to the widespread construction of Victorian Greenhouses, where wealthy horticulturists displayed carefully selected crops of native and exotic fruits, vegetables, and flowers throughout the year. These spectacular structures and botanical displays remain a nostalgic delight among today’s gardening enthusiasts.

Seasonal extenders and year-round gardening.

It is not hard to imagine the conditions that encouraged 19th century Europeans to flock to these eye-catchers. In spring and summer, one could escape the foggy city centers and harsh working conditions to enjoy the sunshine and cool breezes among the abundant foliage, fragrant flowers and ripe fruit. And in the colder months, the warmth of the greenhouses, green vegetation and freshly oxygenated air must have been a respite from the winter cold outdoors and, alternatively, the drafts and stifling conditions in most other buildings.

Many of the original greenhouses no longer exist, but the inclination to use transparent shelter to extend the growing season and enjoy a thriving garden beyond its natural parameters has not diminished one bit. Innovations such as double and triple glazing, as well as the development of transparent composite materials, have facilitated the creation of better insulated, naturally lit growing spaces. Automations that allow gardens to maintain plant-friendly temperatures and adequate ventilation have also helped. And as indoor gardening has become more affordable, the use of inexpensive greenhouses has proliferated among various levels of society, leading to more innovations DIYers find newer and cheaper ways to protect their plants and maintain a year-round garden.

Interestingly, recent studies suggest that gardening operations could be employed to help convicts and improve the lives of wounded veterans, troubled youth and other at-risk populations. however, therapeutic Despite the effects of working the land, not all living arrangements and local conditions are particularly conducive to traditional gardening. Edible plants, in particular, are vulnerable to frost, infestation and incursions by uninvited diners. While rural farms and suburban gardeners may use row covers, hoods, and to keep inclement weather from destroying their crops, gardening presents a unique set of challenges for city dwellers, for whom maintaining a garden could be particularly beneficial.

Fortunately, as greenhouses have become more affordable, they have also become more adaptable. Polycarbonate sheets are quite lightweight and are an excellent building material for smaller greenhouses. In extreme climates, a well-constructed polycarbonate shell can protect tender plants in raised beds or containers long enough to extend the crop, or even winter-hardy perennials. Geodesic domes, constructed of polycarbonate sheeting, inexpensive insulating materials and supplies found at a local hardware or home improvement store can often outlast traditional rectangular structures and withstand even harsher conditions. And flexible composites can be used to fabricate pop-up structures that fit in a few containers, around large pots or even on a modest balcony to allow eager gardeners to get an early start on the growing season.
