We're going to have to replace our greenhouse this autumn but know next to nothing about the best make/type to buy. And should we buy it from a local company or online?
Our current one is 30-40 years old and totally basic. We would like to be able to overwinter plants in the new one and have some automatic heat control for summer bedding plants and seedlings.
Finally, is there a recommended time of year to buy a new one in terms of bargains?
