I went to home depot where one goes to get something to use for a purpose for which it was not intended. This time, when i asked where the lids were for the buckets, the guy (who must have reocgnized me from all my pvc pipe purchases - also intended for other uses) asked, "What are you going to use it for?"

I asked him. "Why do you ask?" I told him.

"We have a new lid which has a screw-in cover. Both frame and lid are gasketed so you ought to be able to get an air-tight container out of this."

If you are sharper than I was, You'll buy dessicant in the little bags rather than a canister like I did. If you do the bags you'll have plenty of room for 5 one kilo spools. With the canister, there is only room for three.

Duh...

So the pregnant question is what should the humidity be? I've searched the internet high and low and no-one seems to have derived a 'safe' number. I made an Arudino Nano based humidity, temperature, and barometer which displays on a very small oled when the button is pushed. This was to settle a dispute about what the humidity in our living room is.

The same deisgn could be affixed to the top of the screw-in lid on the homedepot bucket. I suppose I should just do it and see what the results are, but it would have been nice to learn that the filaments will stay good forever so long as the humity is 20% or less.
