LIGHT:
This garden was created using newer technology fluorescents.
WATER and EARTH:
I used a combination of organics and hydro to create what I later called "Organdro".
FIRE and AIR:
Because I used fluoros the greatest benefits came from the ease of heat management. So I had nothing fancy for air circulation. Some simple house fans.
Humidity was *not* a problem due to the dry climate I live in.
