your base issue might be when they need to be removed due to a sunny day ...

you might not be able to remove them before you leave in the early morning due to cold temps ... but you might not be able to leave them all day as they might get fried as the day warms... and the sunlight and heat is trapped inside ... yes i see they are supposed to vent.. we'll see how that all works out ... i just bring up the issue ... reality will be proven later ....

many of my best plans were defeated by actually having to work for a living.. to pay for all the bright ideas i had in the garden .. lol ...

I don’t use that type of cloche, but have used wall-of-waters on some of my frost tender veggies to get a jump start. The advantage of the wows is that the walls are water-filled cells, and so that keeps the temperature swings far smaller. As Ken mentioned, I often wouldn’t be able to remove cloches before work after a frosty night, but the plants would be totally cooked if the cloches stayed on all day if it was sunny.

I would be more likely to use hoops and row covers of spun bond garden fabric.

I have used cloches some on watermelon plants for a few days. Yes, they do need good venting and watching...hard to do when away for the day.

I have had some trouble with them if it gets about 40° or lower for 3 or more nights in a row. This sets up a wimpy syndrone when it warms up. So I plant a little later now.

I use cloches when propagating cuttings.
