It's a bit of a mess and really not the best way to store gear.

That would have scarred the devil out of me when I was living in Southern California. Once you have lived in Cali for any length of time, you will never look at shelving the same way twice. ![Laughing](images/smiles/icon_lol.gif) |

Is it efficient when you keep silica in polythene cover? _________________ Ajai |

I don't think so small amount silica gel able to control mass amount of humidity for years. That is temporary solution only and I am unsure it is good enough. _________________ -------------------------------

Sorry to dig up such an old thread but I wanted to ask a question, is that box a special airtight box or do you just depend on a combination of reduced airflow and the water absorbing chemical?
I ask because my house has suddenly become more humid than usual, I think it depends on how much rain we have and this year there has been a lot! I was looking through some of my lenses and a lot of them had very early signs of fungus, luckily it's not bad or even internal and just wipes off without leaving any etching because it is still young but I was surprised and it has formed in a relatively short period, perhaps the past few months and before now I have left lenses untouched for years and nothing has happened so there has been an obvious change recently!
Obviously I need to get these lenses into a drier environment asap but I have a lot of lenses and buying a box large enough that is designed to be airtight is VERY expensive, you can get smaller airtight food boxes but I would have to buy about 15 of them!
I'm trying to work out if I can use large plastic storage boxes and water absorbers/dehumidifiers to get things under control, someone said the actual box needs to be 100% airtight but you seem to be using regular storage containers without any problems and I did wonder if that could end up being TOO dry anyway? _________________ - Dave

Ok I'm going to get some asap.
I find the more modern lenses seem to be less susceptible, only one of my AF lenses showed any signs but a lot of the older ones had either the snowflake patterns or little round marks on them and I feared the worst but it all wiped off very easily with some lint free cloth and sterile alcohol, I couldn't find any inside the lenses either so I guess I caught it quick, I had no idea it could grow so fast in the right circumstances!
Time to look for a house that isn't as prone to damp! _________________ - Dave

You know the guys installing "termopan" windows? These are big business now in most eastern europe countries. They have silicagel in quantities. These windows have a container inside the frame so humidity going between the two sheet of glass would be absobed and the dry air act as termal insulator. Ask them for some kg of silica. |

#2 The larger boxes hold the extras
#3 This is a cheap dehumidifier from the $2 dollar shop...It does not work to well so I have to use the more expensive brand

I have bought plastic boxes (non hermetic) and dropped in calcium chloride dehumidifier. I am not impressed. The hygrometer indicates 60% in the apartment and 53% in the box.
Considering the small volume I would have expected a steeper drop in humidity. Any thoughts?

You need to seal the container. But there is a catch; you need to monitor the desiccant regularly because once it is exhausted a sealed container with an exhausted desiccant can actually get to high RH levels once the temperature drops.
Personally I would recommend a rechargeable small unit filled with silica-gel, and pop that into a sealed box. They come in small plastic containers with a built-in mains operated heating element and a detachable cable. Once the blue indicator beads turn pink it means the silica-gel desiccant is exhausted. Then take the dehumidifier out of the box, plug it into the mains and the built-in heater will dry the silica-gel overnight, ready for reuse. I use a number of these in my cabinets and after at least a hundred times recharging (if not more) they still work like new. Something like the ones below (those particular ones aren't the best, but there are many different models/sizes available from different manufacturers depending on the country you are in):
Incidentally, 53% RH is OK; it is low enough to make already growing mould go dormant, and it is certainly not high enough to germinate mould spores. _________________ Mark

Thank you all for the answers. I am reducing my criticism. I wondered what was the point of reducing humidity in the container if you were storing water just beneath. So I threw the retained water and put back the calcium chloride in the box and gained 6% humidity in a few hours at around 45% which is not bad.
I think you must monitor the thing if you want to optimize the results which raises questions if you plan to be away from home for a period of time unless you use electrical systems. _________________ Lumens Pixel
