The WET POT uses capillary action to ensure your plant receives all the water it requires. Clay naturally regulates water absorption - and so the plant can draw all the water it requires THROUGH the pot.
To use, simply down the clay pot in water for a day before planting up with the plant of your choice. Ensure the top of the plant is level with the brim of the pot and that soil is packed tight around the plant. Then all you need to do is pour water through the watering hole until the glass cylinder is 1 inch below the rim - and relax
As long as water remains in the outer glass cylinder, your plant will be able to draw on these water reserves without becoming oversaturated! Clever huh?
