Of course, in a natural system, there is no unused waste, and nitrogen compounds are normally used by plants. As luck would have it, the 4th grades at CHES are just completing their "Structures of Life" unit, which involves growing and studying seeds. So, on Friday, April 17, we started an aquaponics project on the Cayuga Heights Elementary trout aquarium with help form Planted Earth Hydroponics of Ithaca! The waste produced by our trout will feed a small garden on top of the tank!
|Students plant beans and peas sprouted during "Structures of Life" |
into ceramic growing medium.
|April 20 - After three days, the filtering action of the hydroponics media |
(in the black tray) seems to be clarifying the water. Sprouts are taking off,
|April 23 (day 6) - Water continues to clear. Ammonia and Nitrite have decreased |
from 10ppm to nearly zero. Be amazed; we are!
