Här kommer en massa inklipp från diverse håll angående placering. Har trampat på tomten ett år nu i jakt efter en bra placering, nu måste jag bli mer vetenskaplig!
SITE LOCATION AND POSITIONING OF THE GREENHOUSE
There may not be any choice where the greenhouse can go in a small garden. The most important things to consider are, how sheltered will the greenhouse be from strong winds? and how far away will it be from trees? Trees certainly must not overhang the greenhouse or block out light. Those are the two essential considerations.
Other things to consider is the convenience of using the greenhouse in relation to the rest of the garden. Whether a greenhouse runs North to South or East to West is hotly debated. The fact that people can't agree, must mean that it can't be obvious which is the right way, and therefore probably doesn't matter very much. Being close to a tap is important. Even if rainwater is gathered from the greenhouse roof into a water butt, in a dry Summer that butt could well be empty when needed.
Using rainwater in the greenhouse can be a way of introducing pests and diseases. People believe rainwater is best. This can't always be true. Rainwater can be high in toxins and even nowadays may be acidic. To keep a greenhouse as clean and sterile as possible, tap water is probably better. Use the rainwater on the garden plants instead. Research has proved that the temperature of the water doesn't make any difference to the plants (as long as it isn't hot water) even when the tap water is very cold. The practice of leaving a can of water sitting to reach room temperature isn't of any benefit.
It is helpful to be able to reach the greenhouse all the way round for cleaning etc. Even a path just one slab width, all the way around will be enough, Don't plant or cultivate right up to the greenhouse.
Apart from those gardeners fortunate enough to live in very quiet, or very select areas, a stone through the glass from time to time is quite likely if the greenhouse is positioned on the side of the garden adjoining a public footpath, or other public area, such as a park or recreation ground. Being next to a golf course is also a bit of a short straw, as flying golf balls and glass do not mix too well. It's surprising how many gardeners do not even think of these potential problems when deciding on the placement of the greenhouse.
How do I determine placement for a greenhouse?
Ideally, you want to do as little excavation as possible for placement of your new greenhouse. You will need a reasonably level spot that is close enough to the house to connect to water and other utilities. You will need enough space to orient the long portion of the greenhouse east to west, and have an unobstructed southern exposure with at least 6 hours of sun during the winter.
Your Hobby Greenhouse
When you are buying a greenhouse, you will need to study your lawn and garden design before you start to erect your greenhouse. Where will you be placing your greenhouse? Of course, you have many options but here we are going to discuss a few of the details in where to place your greenhouse to maximize your sun exposure and your use of the greenhouse.
You will want to have maximum exposure when you are placing the greenhouse. So you may want to walk around out in your yard about eight in the morning, around noon, again around six and then later if you would like as well to find out exactly what areas of your yard and garden are getting the most amounts of sun. You will want the interior of the greenhouse to have at least six hours of sunlight a day, and this minimum time must be met in the winter months as well to be able to grow plants in the greenhouse during the winter. Sunlight light is important for the photosynthesis processes in the greenhouse, to keep your heating bills lower, and for thriving plants. If you have problems with very-very short winter months don’t despair you could always opt for using growing lights in the greenhouse.
You most likely will also want to think about placing the greenhouse as close to the home or garage that you can within range of the sunlight restrictions. When the placement of the hobby greenhouse is close to a home or garage you are more likely to go to the greenhouse in the middle of winter because of the cold air. When the hobby greenhouse is fifty yards from your home, and the drifts are knee deep many of us, including me, think twice about wanting to get out to the greenhouse!
You also need to think about the trees where you are going to place your greenhouse. If the tree branch, or the tree itself would fall - is the greenhouse in the path of the tree or would the tree damage the greenhouse if something was to fall? You may also want to consider looking over your homeowners’ insurance policy. If you are using your greenhouse for your personal use, it will most likely be covered under your homeowner outbuilding on your insurance policy, of course all insurance policies are different, but this is how mine was handled. Unless you don’t have another building on your lot, but it is always good to tell your insurance agent about your greenhouse just so they can list it in case something would happen to your greenhouse in the future because this is an investment.
