How do frames work when gardning?

I started seedlings. Had a planter not in use. Black fabrick at bottom. Placed the Jiffy pots with soil and seeds inside & covered with clear, plastic Visqene. 
It will get hit during day but will it keep it warm enough at night? Days are 70's to low 80's. Nights we still have a slight chance of frost. Even hear of snow on Mother's Day on occasion. 
Will the plastic be enough?

they work by using sun light to warm the ground. within the frame. 

In day time warm weather you open the top of the frame, to keep from over heating the plants. adjust the "lid" to allow more or less heat to escape. 

close the lid before dark, to keep the plants warm. the ground would be warmed all day and a closed lid at night holds the warm air in. The ground is a "battery" of warmth for the tender plants. Its charged by sun light and kept in by the closed frame. 

Most frames have glass tops/lids. so that all the spectrums of light are available to the plants. Some plastics will not let full sun spectrums onto the plants.
