Well recently i inherited a small self -contained plant set up. It consists of four plants in some potting soil, each about 3 feet tall. Its neon green appearance is very impressive. It is enclosed by mirrors and flouiant bulbs all around. It also has a timer set for 12 hours on and 12 hours off. There are tubes running into the soil and out to a pump and water container, also a glass tube sticking out of the soil. I've been watering once the top inch soil feels dry. I dont really know what else to do, so any tips would be greatly appreciated. Thanx.
