In my experience better to keep them in dry cabinet than in room with air if humidity is high. _________________

Very true, Peter, I forgot. Ventilation is important to prevent fungus.
I open my cabinet several times a day. And the dehumidifier is a chemical one and thus constantly active. It just has to be recharged (just by connecting it to the mains for an hour) every two weeks. The little dhumidifying balls inside are dried then. _________________ "KAPCTEH" | "Karusutenu" | "Carsten" | T-shirt?

Don't forget to measure humidity continuously,modern windows keep to much humidity inside in room. _________________

As a use to be gun collector the solution to the humidity problem is here.....
http://www.goldenroddehumidifiers.com/
I'm building ...or may buy a safe very similar to a gun safe for my cameras and lenses...fire resistant and with a UV light inside it is as good as the sun without the dust problem. The golden rod stick will keep the humidity down.

I'm making something similar - a bookcase with glass doors and two 4' fluorescent lights mounted vertically inside, with a tubular heater like the Goldenrod at bottom, but also using a small Peltier dehumidifier in the cabinet, coming on for a few hours per day.
A heater on its own will have a significant effect, but in itself it's not really a very good dehumidifier. _________________ Dave

Our government has kept us in a perpetual state of fear - kept us in a continuous stampede of pseudo patriotic fervor - with the cries of grave national emergency. always there has been some terrible evil to gobble us up if we did not blindly rally behind it by furnishing the exorbitant funds demanded. Yet, in retrospect, these disasters seem never to have happened, seem never to have been quite real. - General Douglas McArthur
The whole aim of practical politics is to keep the populace alarmed (and hence, clamorous to be led to safety) by menacing it with an endless series of hobgoblins, most of them imaginary. - H.L.Mencken
The people can always be brought to the bidding of the leaders. That is easy. All you have to do is tell them they are being attacked, and denounce the peacemakers for lack of patriotism and exposing the country to danger. It works the same in any country.

I was very worried when I came living here last December. One year ago I measured the humidity in the ground floor and it was 78% in a day when in my previous apartment it was about 50%.
Now, after the restoration works, I don't even have to use the boxes to store the lenses. I have an average humidity of about 42%, which can go to 45% or at the very worst near 50% when it rains outside. During good weather, it is lower than 40% (two days ago it was 38%) so I might actually start to worry about lack of humidity!

I store the lenses in cabinets with glass doors, do nothing else.
Where I live is fairly dry place even though it is close to the lake Ontario,
but the apartment is air-conditioned whole year round and humidity is
always between 30% (winter) to 50% (summer). For humans it is a bit
low side, but the photographic lenses it seems an ideal condition.
I do not even open door for a week or so, although doors are not air tight.
So some dust is accumulated eventually, but not much. We use 3M's
air filter for our heat-pump, changing every 4 months. Its grade is 1,700,
ie. it stops larger size bacteria accoring to their description.  _________________ My HP contains 4,340 photos in 315 directories today.

Posted: Thu Mar 05, 2009 8:10 pm Post subject: Storage System |
|
|
For lens storage I use a system of 3 Pelican Cases each with renewable dehumidifiers and min-max temp-humidity gauges. Temperature varies, but humidity is always 20-25% in cases 1 and 2.
case 1. lenses and equipment used infrequently.
case 2. lenses and equipment I shoot with more or less regularly.
equipment moving from cold to warm environment gets sealed in plastic bag first, to prevent condensation while it warms to room temperature
case 3. used as a "dryer"; lenses fresh from the field go in here to dry before moving to case #2.
here's some of what i know about fungi:
fungi are everywhere. infection is universal. fungi can be murdered, however new fungi grows particularly well on the corpses; clean it off! growth is easily prevented by keeping humidity low. air flow prevents fungi growth only if the air drys out the fungus; the air must be lower in humidity than the fungus; increasing air flow also increases the amount of fungi. _________________ like attracts like! |

The bottom level is flexing....I would recommend you displace some of the excess weight by sending me some of that good stuff!
In regards to the OP, like others, a cabinet. Unless you live in a relatively humid region, I wouldn't worry about it at ambient atmosphere.
If humidity is a relative issue, a diy'er can build an air-tight plastic chamber (I've seen a few done from those plastic compartments that people store clothes in) and perhaps throw some absorbents in there for good measure. |
