Ok well that should be a lot better than a smaller one. As said it will be controling the temerature and condensation. My smaller one gets scorching hot during the day and back down to freezing overnight if its not opened up during the day. I put buckets of water in mine to weight it down and help retain a little heat overnight although im not sure it will be as effective in a much larger one. I think however your main problem will be securing it enough to not blow away. My smaller greenhouse even though was weighted down with very heavy tiles literally blew in half at the middle and the cover tore to bits. Despite trying all sorts of ways to tie and weight it down it has blown over at least twice each year in the last 2 years.
