If you do keep your containers under open sky, do you move them to a somewhat protected location such as under roof overhangs etc so as to protect snow/ice once the seeds sprout?

or you keep in the same spot from day one up until they get planted out in the garden. I'm assuming seedlings will need sunlight when they sprout? So if you are placing them under protected structure, you have to ensure that you get atleast few hours of sun when it is sunny out in spring.

Can you be little more specific as to what you do after they sprout? Till they sprout I can understand they need little care. I also read about opening the top as the weather heats up.

-against the foundation, South side of the house
-out in the open on the driveway- south side of the house
-out in the open on a table- North side of the house

Cap...you mean the little one on a milk jug? Throw it away. It's not used.

I typically don't move containers, and they usually don't sprout until the snow/ice season is over. If we have a rogue snowstorm in April, oh well. It's not likely that too much would get inside them, anyway.

Because our change of seasons can be pretty erratic in the weather dept, there might be days that get up to 70 and I'll take the tape off my sprouted containers and flop back the hinge so they don't fry during the daytime, then flop it back over at night if the temps haven't consistently been ~43+ (that's my own personal degree mark).
This might go on for about a week until the temps are more stable. But this on/off thing is not something that everyone does, nor is it "routine."
I just don't want my containers heating up to 90 inside and killing my seedlings (I also go by the container temp can be 20 degrees higher inside than the air outside, so when it's 70+ outside, I don't want to kill them (btdt one year- oops!))
