Hi,
Avoid storing the camera next to some device that generates magnetic field like tv, or temp differences. Also, in a place where you know the temp do not change too much within the day.
Here in Madrid, it hardly rains, (that's why basically I choosed to live here) this is a very dry area so we don't care at all about humidity but humidity is to be taken seriously if you are located in for example Vancouver.
The ideal should be to have a conditionned room with temp and humidity controled, where you could also store the printing papers and the prints themselves if you do it at home. So idealy, the case should be stocked in this room. If you don't have such facility, ventilate regularly. Avoid location next to a bathroom wall for example, or next to a heater.
You should also open the flight case regularly and put the equipment into function for awhile. I'm not very certain that the silicon bags are usefull to be honest, and they have to be changed also regularly.
Never ever put the material in plastic bags. The vintage "leather" hoods are better than what we have now but don't close completly the zip.
In fact, dryness is the best. That's why the pyramides are still with us today in such a good state, no?
