Long-term storage and humidity

[skilfautdire]

I'd like to actually know what's the degree of humisity where tea is stored. Any hygrometer that's recommended ? And what would be the acceptable range for long-term tea storage (puerh, green, black) ? All loose teas in sturdy 'aluminium' zip-sealable bags gotten at Upton), each one then being put in a regular plastic bag. Puerh are mostly in their paper wrappers, some cakes also wrapped in (bamboo ?) large dried leaves.

I think it is too humid, not sure.

Thanks for any suggestions/hints.

Pu-erh Storage
* Keep the storage space free from odors.
* Do not use unsuitable packaging materials wrap the teas.
Breathable packaging is suitable for aging, just keep it in original
factory packing is fine.
* Maintain a proper air flow.
* Do not keep it in a damp musty basement. 70% humidity is a good
target.
* Avoid high fluctuation of temperature.
