David Omick and Pearl Mast are wonderful practitioners of productive and joyful simple living.
You can see many examples of this on their website, Omick.net
Below are images of how their raised vegetable bed (raised to prevent predation by javelina) harvests moisture condensing on the underside of the plastic used to cover and protect the garden in the cold winter months.
Condensed moisture drips off the plastic back into the garden soil, or runs down the plastic with much of it going back into the garden soil.
Plastic-free options
It would be great to explore non-plastic condensate- & dew-harvesting coverings, or even living coverings—examples of which you can see here.
