Hi,

Just curious what people use as drying agent for their dry box. I used the hippo thingy (the one that come in a packet).

The uncle try to con you, no way silica gel can last that long. Even if he keep the drybox unopened for long periods, moisture will still manage to seep in somehow.

I thought regardless of what you use, dry cabinet is still the way to go.
A little hard to monitor humidity with silcia gel and hungry hippo.
Ideally supposely be about 40-50% RH.
Unless u buy a humid gauge you might be over drying your equipment.
Not really expensive anyway. 130bucks?

Actually, silica gel or thirsty hippo would give you about 40% RH...which is ideal for storage of your equip.
Its really a preference if theres a need for a dry cabinet or even a dry box (a normal tupperware lookalike would do).

Saves your $100 upfront. =)

Used to use Silica gel last time but messy. found the hippo thingy neat and clean. Used those lock it box.. seems to be working well. Thinking of using another box for the lens since i remove and put in the body with lens quite often. Hope this way will minimised the exposure of the lens to moisture. Any one do that?

It's a one-time upfront payment for the cabinet, with really low electricity consumption. And you are more or less guaranteed that your equipment is stored in a controlled environment.

I don't understand why everyone wants to try and use thirsty hippo and all, where you have to keep replacing it from time to time, and you are not even close to 100% sure that you have the right RH% value.

I have a spoilt dry cabi, the electronic part kaput after few years and replacing the part alone is as good as buying one, I did bought one.

Nevertheless, I modify the spoilt one a bit to airtight it and place a Hippo or equivalent inside. It was a 26L one. It has been 5 or 6 months and I havn't change it and the Rh is 30% - 35%. I store my old camera or old electrical stuff. Silica is way too troublesome, need to change very often.

Bro calebk has his point too. If you intend to go into SLR n stuff better buy a decent one as even with the method I use, I can't control the RH level . The hippo takes quite a space in the cabi.

just my 2 cents

Do note that 30%-35% is a little too low for equipment storage. Lubrication within your equipment parts, and certain rubber parts may dry up, causing cracking.

Ah ha, same here. Got a spoilt dry cabinet, use a hippo or equivalent (can't remember the brand), was able to maintain the 40-45% RH(this reading was taken with multiple hydrometer, analog and digital) for more than half year. However, my main equipment are still kept in the newer DigiCabi ;p

Have been using dry box & silicon gel for 5 years for my 10D & 2 L-lenses and still no problem. Its personal preference. I do not want to warm up my room, so no electric cabinet for me and save electricity :)

Your presence alone (without doing anything) brings in additional warmth of about 83 Watts. The power consumption of a 100l dry cabinet is about 5Watts. Most of it is used to create the temperature gradient at the Peltier element.

I think that are enough electrical stuff at home. don't wish to add another one. btw, do people bring a small dry box for the lens when says travelling for more that two weeks?

i found that the bottle of gel that I paid $5 for is going for $3.90 at carrefour. Anyway for me i have a hydrometer in my dry box and my gel is keeping it 40~50 so until I intend to get more equipment, I dun think I would get a dry cabi. Or at least until I find space for it in my room as well.

Erm...the dry box, no matter how air tight, will still have moisture seeping in once you access your equipment. Has that ever occurred to you?

Unless, of course, you mean to say that your atas air tight glass container is brought into a dry room whenever you store/remove equipment.

Yes, i agree. The RH% is only as accurate as the attached hygrometer. This is regardless whether you use a cabinet or a thirsty hippo setup.:)

Pls note that sillica gel is carcinogenic.

And how much power does a dry cabinet take?? 5 watts only. Your bedroom light is already 32 watts.... :sweat:
