Yup, on suggestion of GWRS is this the start of a greenhouse thread. Mine, for example, is at the moment housed in an 80 year old garden structure that was used in the past to store food, chairs etc for bbq parties. But the structure is falling apart and I am sharing the space with a few cute mice. That means a new greenhouse in a better position is on the shopping list... and was for the last three years... and will be for the next three years.
What is your greenhouse like? What problems have you faced and how did you conquer them?
