I have a 40' container that I want to use to store furniture and appliance. How much of gel desiccants will I need to take care of the moisture? how long will it last and how much will it cost me?
Providing the vents are closed and you don't reopen the container regularly I would advise using one carton which is 64 pieces. Desiccants are generally used for transportation protection, not so much storage so you need to monitor the desiccants weight if you are regularly entering the container and allowing fresh air (containing moisture) into the container.
