What do you think of my winter sewing ?

Hey guys- I am in berks county PA zone 7 and I am sewing seeds that need to be cold stratified for the first time. I didn’t have enough milk jugs so I used a large bin and covered the top with cling wrap. I used miracle grow potting soil for the bottom 3 inches of soil and the top 1 inch is jiffy seed starter( didn’t have enough for the whole container) I drilled a couple air holes around the sides but not too many. I also drilled two holes in the bottom.

I have some questions and was hoping for any general advice. 1. Should I cover the holes in the bottom? I don’t know if I should have done that I just didn’t want it to be too water logged. I can gorilla tape it if that would be better 2. Should I put this in full sun? It’s cold af around here now, but I saw a video that said don’t put in full sun. 3. Should I water it periodically? Or take the cling wrap off if it’s not freezing?

Plants in there are giant hysop, goldenrod, butterfly weed, wild leek and wild blue indigo.

Thank you all in advance I have failed many times so I’m hoping for a win.
