I need t know about an aquarium I'm using

I have that 55 gallon aquarium (I'm sure I've asked before, but need help so here I am again.
I put it out side, put plants in their containers in there and put a glass top on it. I did put plastic at one end so I could put some holes for ventiation.
Question is, I didn't put plastic on the small containers, etc. Should I have?
My daughter in law has a greenhouse, but I can't remember how she does it.
Just anyone smarter than me, help me. And anyone is smarter than me, my cat even thinks he is

The individual lids are to increase humidity. If that's ALL they do, then the lid on the aquarium should be enough. I've got starter seed packs in giant ziplock bags, there is humidity in the bag, so I didn't put individual lids on each peat cell.....

Let us know if it works!

I'll probably get them out and put the plastic on them. I use the ziplock bags too, on everything but the ##X#* aquarium. I'll check it tomorrow and see what's going on with them. We've had some really tough wind, so at least they are safe from being blown away.
I guess I was thinking about it being a big old baggie
