How long to test cache for?

A little birdie mentioned to me that after gluing on one cap to your tube to turn it vertically and fill it with acetylene gas then glue the other end on and go do your thing....acetylene is heavier than oxygen and will stay in the tube. I am not sure if that would be corrosive or not myself..thought anyone?

Do not do that! Acetylene will soften the ABS/PVC and eventually eat through it!

Depends on what type of freezer it is…

A frost less freezer will but one that doesn't thaw and dehumidify won't.

Didnt realise that they still made anything BUT frost-free freezers these days..

Excellent info, I will go clip the birdies wings! LOL!

Just a little tip, and something to consider in site selection... checking for negative buoyancy is a good idea before burying your tubes... if you go that route.

A sealed tube with any positive buoyancy can find it's way to the surface if the water table rises or with heavy ground saturation. Also to be aware that with negative bouyancy there runs the possibility of your tubes dropping below their initial bury depth.

Compacting and lining the bottom (and/or sides) of an in-ground cache site with bricks or pressure treated lumber can help your cache tubes stay put. Providing weight displacement, water drainage and, if you want to go the extra mile, an anchor point for your tubes. Another option being a 50gal drum (or similar). Loading your tubes vertically in a vertical drum and backfilling the inside. Any drum though would need drainage holes.
