I was doing some readin about the pros and cons to some of those mini greenhouses. And a lot of people said things like the plants can get mold, dampen off, fry etc if kept zipped up. Soem other people said a solution is to leave open/ventilated during the day and then zip up at night.
This is once the plants are up. I was thinking that since they are outdoors they would get hardened off on their own.
