The first decision to make is where you intend to site your greenhouse; this may dictate the style you choose and the material of the framework. You need to then consider the size of greenhouse, remember that generally freestanding glasshouses are best positioned with the ridge axis running from east to west. Keep your new greenhouse well away from roads, trees and play areas. Accessibility is important for several reasons; you’ll definitely want to be able to nip out to the greenhouse whenever convenient, so keep it fairly near to the house. If you want water and power to be connected then it is more cost effective if the greenhouse is nearer the relevant existing supplies. Plus when you buy a Growhouse you are investing in a greenhouse to be proud of, you don’t need to hide it away at the bottom of the garden; make a feature out of it.
Think carefully before you make your final decision. Consider buying a size bigger than you think you need or be prepared to buy another one! Greenhouse space soon runs out when you’ve pricked out a few dozen pots of seedlings into thousands of individual pots and modules.
Your final choice relates to the material of the greenhouse frame. There are two main choices timber or aluminium. There are benefits to both these materials and it usually comes down to user preference. Experienced growers tend to opt for a Western Red Cedar Frame, but an aluminium-framed greenhouse still remains the most popular choice for British gardeners. Whatever you choose you are sure to fall in love with your greenhouse and spend many, many enjoyable hours, sowing, growing and gardening.
