The VHCC Greenhouse Facility is composed of two
gutter-connected aluminum-framed greenhouses that provide over 3,500 square
feet under glass. Each greenhouse is approximately 25'-0" wide by 73'-0"
long with a gutter height of 12'-0". One greenhouse is divided into three
(3) compartments, (2) 31'-4" long greenhouse zones and (1) 10'-3 3/4" long
corridor. The greenhouse is to sit atop a 2'-6" brick/concrete kneewall. The
largest greenhouse serves as an indoor garden with approximately 1,800
square feet of growing area.
