Store electronics in plastics bags due to humidity?
 

Is there a problem if I store and tie inside a plastic bag the box with my Gigabyte Motherboard and other electronics inside the Plastic bag? components get humidity and damage the electronics?

This will have the opposite effect. The bag will actually cause humidity. A thick cardboard box with silica gel packets will be better. The silica and cardboard will absorb moisture, not trap it.

Haven't you ever seen water drops collect in a sealed plastic bag?

I have no silica gel and is very difficult to find it

all parts of the pc station storage in their original containers and packaging station in plastic bags, these bags station in a cool place

That's what eBay is for. http://www.ebay.com/itm/like/2813303...lpid=82&chn=ps

PC parts are not in "plastic bags" exactly. Those are anti-static bags. Not the same.
And those contain silica packs as well.

You asked how to do it. That's how. There's no other ways. Cardboard and silica. Only use anti-static for things that needs it (hard drives, graphics cards, etc).

as I said before all the pieces of my pc station in their original packaging and antistatic bag and all this in common Plastic bag
