About this 3D model

I can't keep a plant alive. So I created a "Plant Incubator" that will give my plants everything they need. The light (On the top) is on a 12-hour timer simulating a day-night cycle thanks to my Arduino Uno. Underneath the dirt, there is a body of water. Some wool is soaking up the water and bringing it up to the plants' roots. To refill the water there is a hole in the pillar keeping the light up, leading down to the body of water.
