No it won't be the same as a conventional greenhouse but they are so useful to those of us who are unable to have the 'real' thing for various reasons. I have three of them of various sizes so quite a little village. At the moment growing in them are broad beans. runner beans, sweet corn, mini sweet corn, cucumbers, sweet peas, cosmos,sun flowers, cornflower, honesty, lupins and tender fushia I use them to start off the aforesaid plants which will eventually go out into the garden and allotment. You have to be careful of temperature and not forget to open up the front before you go to work as they can get very hot inside and then close them at night before the temperature drops. As others have said make sure you secure it to something in case it blows away with all your precious seedlings.
