Last year, I was not satisfied with how the tomatoes were pollinated in the cold frame. The probable cause was that when the temperature drops at night, the relative humidity in the frame increased to over 95% and the pollen was damp. During daytime temperature rise, he did not swell and therefore did not pollinate.
The second problem was planting and harvesting fruit. I did not have access to the plants in the middle row.
I'm trying to solve both problems. I'll be watering with a hose with a hole underneath a black cloth. From the planting until the glass removal, I cover the whole area of the cold frame with a thin transparent foil to prevent the evaporation of water from the soil. By this measure, I want to achieve that the relative humidity does not increase to 80%.
To have better access to the plants so I made a wooden grid I shall put on the foil.
PS.: I am adding photo illustration how I shall deal with watering and access to the plants.
