Can my farm work normally on a sky island in an empty world?

I have a city on a "sky island". I want to have farms around my city on all the rest of the island.

There is nothing around the island no matter the distance or direction. But the gravity works (meaning that all that is not the island feels a force of attraction directed downwards and "downwards" is an absolute direction). If you fall from the island you will die of hunger, thirst or boredom. The water is supplied by a fountain that fills ponds and canals. When the day comes a diffuse light appears everywhere. Therefore a cellar large enough even closed will be lightly illuminated. But the weather is monotonous - no rain, no wind and a constant temperature. There are trees on the island, but no forests and all the water bodies are artificial channels

With such a world, I am worried about potential difficulties for my culture and my farms. Then I maintain farms identical to that which can surround any city on earth under a temperate climate? The water supply is not a problem but is not due to the rain some cultures are better suited than others? What impact can the absence of weather and especially wind of the flora and fauna of the island?
