Purchased a carcoon this year , got a hydrometer, over the last few days I am gathering data
Reading up, a carcoon is primarily about controlling the dew point , my understanding is when the air temp equals the dew point temp , air is 100% saturated , condensation, fog can occur

Over the last few days
The carcoon air temp is 5.7 degrees, 66.9 relative humidity and 0 degree dew point temp , low risk of condensation

Garage
It was up at 15 degrees in the garage with the sun out and 49% humidity
Garage
It got interesting when I seen a big shift in temps , 2 degrees to 14 degrees within 12 hours (allegedly the carcoon has its own controlled climate , compensates for the temperature swings , in theory it should not see a big swing in temps within the bubble , resulting in no condensation)
Unfortunately, it has not done its job, Aluminium parts have condensation on them, Aluminium has different chemistry so I assume different thermal properties to steel but still, defeats the purpose of it ,
Occured at
Carcoon
Note: steel does not appear to have any condensation
Conclusion to date
I am still on the fence , need more data
It will stop damp rising from the concrete slab , stop rodents
I read 55 to 60 is the relative humidity required to stop rust , need to research if high relative humidity environment is ok once the air temperature, and dew temperature do not coincide , high humidity but no condensation
I purchased another hydrometer to put in the garage as a baseline, I can compare the carcoon environment Vs garage , carcoon in theory stabilises it environment, no temperature fluctuations, no condensation, mould ; interesting the difference, if any in data points
It is basically a plastic bag with two pc air fans , I am sceptical
I cannot find anything online contradictory or factual data to back it up, long term users vehicles have no rust but I have not come across any who stripped a car after use , I am more concerned about unseen areas not directly exposed to the air flow of the fans
I could put a dehumidifier in there but it's expensive to run and carcoon state you don't need one
Will try some silica cat litter, it may reduce the humidity or maybe nothing outside of a dehumidifier with these big temperature swings
