Welcome to NGA, @I8taterz
Congratulations on moving to a new home -- one with a greenhouse, no less! I agree that we need more info -- how large is the GH? And a photo or two, plus your location, would be extremely helpful. Depending on where you live, it's not necessarily true that you can't grow anything in it in the summer; I have tomato and pepper plants growing in mine -- up here in northern Michigan -- and they're doing great.
I'm looking forward to hearing more from you -- are you an experienced gardener, or a newbie?
Edited to say: sorry, I see the title of your post says you are new to gardening!
