This indoor aquaponics garden grows with the waste from a few Goldfish that live in the reservoir. Plants are growing in a 2ftx4ft flood tray under a 4 tube T5 fluorescent grow light. The water pump is set on a timer to flood and drain the grow bed for 15 mins every hour. Growing fresh lettuce, parsley, watercress, and lemon balm. Some sort of Water Sprite is growing in the reservoir, if you have more of an idea what it is, please let me know!
