Is this likely to work. I have around 36 x 3 inch pot plants with seedlings. I intend to put them on a large tray sitting on several layers of newspaper, tilt the tray slightly so there is a deep & shallow end. the pots will be at the shallow end, the idea being that the pots will soak up water from the wet newspaper. To keep a supply of water I will fill several 2 litre bottles of water turned upside down with the neck in the deep end. The theory being the water will only come out if the level in the tray drops below the bottle neck and only an amount that will cover the neck of the bottle.
Tray will be in a shaded place not getting sunlight so less evaporation. Located in Scotland so chances are it will rain anyway.
feasable?
