# Is there a miniture atmospheric water vapor condenser?

I am looking to add a condenser for a plant preserving container. The plants need water and I was wondering if I can have a passive method to condense atmospheric moisture to water. My container is small and I would like the condenser to be as small as 30 cm$$^3$$ (but I can be flexible). Is there a current passive miniature air well (condenser)?

My container design can be changed to fit the condenser (so it is irrelevant). Therefore I would like to find a passive condenser that is small enough but enough to water a plant continuously.

(note: I am not asking for a product, I am asking for a mechanism or a technology or a method)

• Seeking product or vendor recommendations will get your question closed so I suggest that you edit to fix that. Why can you not seal the container to make a closed recycling environment? – Transistor Jan 11 at 21:56
• This looks like a resource-hunting question. Such questions are prone to becoming out-dated, and are therefore considered off-topic for this site. – Wasabi Jan 11 at 22:15
