>_< i get the idea, but where do you find a $120 dry cabinet? :L the cheapest i've seen so far, from websites and stuff, is close to 200 dollars.. :/ and i'd still need about a month or two to save up that kind of money, because i'm still a student, and i'm not holding a part-time job.

You noticed that there are different sizes? the smallest size (30-36l) is slightly over 100 bucks. for 200 you can get already 60l. Check with camera shops like MS Color and others, some have small dry cabinets ex-stock.
Here are some material. If need to use silica gel, try to find the orange-green type.

i did an experiment using digital hygrometer ...
-1st week, using the 'sd' dehumidifier in the dry box, with my camera &
-5th week, using the 'sd' dehumidifier in ziplock bag (with my camera too)...
-both are in the same cabinet. each experiment lasts 4 weeks.
both readings came out at that RH% i mentioned...
but its just a testing i did, just in case i have to travel, & cannot simply lug my dry cabinet along wherever i go.
Refreshing systematic testing :thumbsup: seems the bags of dehumidifier are of the right size for the small volume of air.
Personally, I don't drag any dehumidifying stuffs around when traveling. Traveling is the opposite of storing, plenty of fresh air and sun, no need for anything related to long term storage.
You certainly did a good comparison. Thanks
OK, I am now trying this and see the result too. Then I can figure out adjustment in my tupperware.
- 2 layers of Raynolds ziplock (non deflate, leave air inside).
- 1 sachet Fairprice Jumbo dehumidifier.
- 1x videocam pouch and videocam that has been in open for 1 week (forgotten to keep).
- 1 hygrometer inside, wire probe located to the pouch and vcam end.

i feel that the those box dehumidifier can be too much for a small space...i think sachet may be a better option.
Check the climate statistics for that location. Afghanistan is a bit bigger than SG, please specify further. But still, better get good camera bag, don't waste time with silica gel or other stuffs.
Does that mean if I shoot everyday, I don't need to get a dry cabinet or dry box? :bsmilie:
The dessicant in thirsty hippo is calcium chloride. It corrodes when the material in
contact with moist calcium chloride.
This chloride thing.... Don't know lah.
You all go and pour the dissolved liquid from thirsty hippo to you camera and clothing and hands. Then let me know the outcome :bsmilie:
You will then notice that is not ordinary liquid, it is very soapy, slimy and does not evaporate easily.

Woah you might as well ask me to throw the camera into the swimming pool! :sticktong
So simply put.... don't use it for your travel drying agent. If you have a simple box that's upright and stationary... the CaCl agent base won't be a problem.
