im sure someone has asked about this before but i didnt fancy going back through all the old threads. i already have an 8 by 6 greenhouse but have been offered another one of the same size for free. the one i currently have isnt in the best spot and gets quite a lot of shade in one end. i will have to move/disguard plants to fit in a new one but im not sure what the best place is for one to get the best light etc.
