tanks are heated using a water heater. An
ideal water temperature is 70 degrees.
Here are some floor plans from typical
gardens.
- A closet 9 feet high by 36 inches deep
by 40 inches wide. This space did not
have convenient dimensions for using
fluorescents, so it was easiest to use a
MH or HPS lamp (see page 28). The
total space was about 10 square feet.
A 250 watt MH lamp lit the space. A
shelf was constructed at half the
height. The shelf supported a second
garden. Each garden was powered by
a 250 watt MH lamp. Ventilation is
provided by keeping the door open. No
CO 2.
