Space Saving Greenhouses

If you haven't got room for a greenhouse, or you have a small space that you want to make use of, a lean-to greenhouse is an excellent alternative to a free-standing glasshouse. By fitting neatly against an exterior wall, it's a design that works beautifully in more confined outdoor spaces.

However, if you're just going to use your greenhouse in spring and summer, it's better if the ridge runs north-south so both sides of the greenhouse get an equal amount of light. For lean-to greenhouses the best location is south-facing, with the supporting wall on the north side.

A lean-to Greenhouse should be placed along a south-facing wall, whether that is along the wall of a garden or a property's external wall. This is so lean to Greenhouse can receive the maximum amount of sunlight to ensure your plants grow and are kept protected from the elements.

Don't put your greenhouse directly under trees. They'll cast shade, which encourages green algae to build up, blocking even more light, while falling branches and leaves can cause damage and block guttering. Honeydew from insects on the foliage of trees can make the glass or plastic sticky and dirty.

For effective ventilation:

Open all doors and vents on sunny days. These can be left open at night if the temperature remains high. It is sometimes necessary to temporarily remove panes from glasshouses to assist ventilation in heat waves. Fit automatic vent openers to ensure roof vents open even when you are not ...

The industry produces over 3.3 million tons of greenhouse gas emissions annually, which significantly impacts climate change. Even though greenhouses themselves aren't bad for the environment, constructing greenhouses produces pollution and adversely affects the environment.

Plants raised indoors or in a greenhouse need to be acclimatised to cooler temperatures, lower humidity and increased air movement for about two to three weeks before they are planted outdoors. This 'toughening up' process is known as hardening off.

A good greenhouse floor will protect it from moisture and pests, and it will make it easier to keep the interior clean. In addition, a floor can add insulation, which can help keep your greenhouse warm in the winter.

The best spot to place a greenhouse is the sunniest spot. It's important that the structure (and therefore the plants within it) receive at least six hours of winter sun exposure.

Mostly south-facing is the goal, but in cases where that is not possible, a southwest or southeast facing greenhouse is doable. Southeast is preferable to southwest because it will get the morning sun, which helps heat up the greenhouse after it's cooled down overnight.

What are 3 disadvantages of greenhouse effect Why? ›

For that reason, the greenhouse effect, far from being our great ally as was the case in the past, is now a risk to our survival. The flooding of coastal cities, the desertification of fertile areas, the melting of glacial masses and the proliferation of devastating hurricanes are just some of the main consequences.

Greenhouse gases have far-ranging environmental and health effects. They cause climate change by trapping heat, and they also contribute to respiratory disease from smog and air pollution. Extreme weather, food supply disruptions, and increased wildfires are other effects of climate change caused by greenhouse gases.

Disadvantages of a Freestanding Greenhouse

Due to all four sides being exposed to the elements, freestanding greenhouses are less energy efficient compared to an attached structure. Freestanding greenhouses are less convenient to access because the gardener must go outside to enter the greenhouse.
