you spend more than $1k on a camera and you can't afford to spend 1/10th of that price on a cabinet?
eat. drink. shoot
www.silicagelpackets.com is a good site to get Silica Gel from, they are one of the few that carries the orange to green indicating Silica Gel.
I am using the silicagel too in a dry box. but i do not have a hygrometer. will those tat are sold in ntuc for Homefix shop suitable to use? it's called a digital hygro thermometer. it's a 2 in 1, temperature n humidity reading.
I may sound off track but since this thread is about using silica gel.. i tot i can ask about the hygrometer as well...

Saw that the orange silica is in bulk of 4.5 pounds. looks quite big. Any other from the site that fellow members here uses??
I am using the blue silica gel. but if you guys here say the orange one is safer.. then i m considering to change.
I am looking around for orange silica gels too but cant seems to find them. Can we get them anywhere in singapore? Dun really want to go through the hassle of online purchase and shipment.
i use my camera daily
so silica gel in airtight box
i travel overseas
so buying a dry cabi seems like a bad investment

Here is more observations.
2 new (diff model) of digital hygrometers have the same highest and room reading value but yet different dry reading. E.g In plain silica gel (one goes to lowest limit of 10% while another stuck at 20% when both specs say 10-99%).
- Silica gel has the best absorption power (abt 50gm) can drive the ziplocked item to 16% overnight. In the empty bottle test (with just plain ha ha breath), it will reach minimal (I suppose to near zero bec meter has limit) within an 1/2hr (thirsty hippo sachet take about 1hr). So if you like your things to be good dry, silica gel is the one.
- In the brand test of Thirsty Hippo vs Fair Price Jumbo (and whether more sachets drive humdity lower) will have to wait longer. Why bec once the pouch is dried up, even full half day in the open doesn't damp it well.
* Of course all these are not related to your equipment drying as you don't need that low RH.
With all the hassle of checking the thirsty hippos, gel packs and dry boxes, save yourself the trouble and get a dry cabinet. A good dry cabinet will last you for DECADES. As the ideal setting is between 45-55% RH for electronic equipment, the dry cabinet is a set-and-forget item. As you take stuff out to use, you can always peek at the reading and check to ensure it is between 45-55%. If it's too low, you may risk drying up the lubricants in the equipment. I think it may be too much of a hassle for you if you use other means.
Besides, you can also store your video cam (if any) and other expensive electronic equipment.
Hope this helps.
Before I begin, let me quote from a fellow forummer, "a photo a day keeps the fungus away".
I was just thinking, instead of getting a dry box like this one, might as well just ziploc and throw in silica gel.
Fungus grows in dark, damp and warm conditions. The dry box does not allow any (sun)light in, unlike a dry cabinet which has a glass door.
Hygrometers are not always accurate, at least with the dry cabinet, there is light entering, but not with a dry box.
I've looked at some of my cabinet doors and walls, there are yellow/brown spots and patches on them. I'm not sure if its fungus / mould / whatever, but obviously they aren't something pleasant.
Interestingly, the cabinet that is not opened regularly (hence bad air flow) but has a glass 'window' to allow light in did not show signs of the yellow spots, and the ones which are opened regularly but did not allow light to pass when closed had only very little of the spots.
As you'd expect, those that are not opened regularly and had no sunlight were the ones badly infected by the yellow spots.
If those spots are fungus, then I guess sunlight is a big factor in preventing fungus growth - at least on my cabinet.
Just sharing my experience.
do we have to put e gels in ziploc bags??
I poured 1 whole can of gels direct into a lock n lock box, then a piece of plastic divider with lines/ lobangs, then A4 plain paper, then my cam. lasted for 3 mths before i c some gels turned pink, mostly still slight bluish.
is 1 whole can of gel too much??
If put gels air tight in ziploc bag going to work e same manner as in direct pour into box??
