Glass greenhouse still under construction. Note aluminum entry doors and slant wall Acme exhaust fans for this cell. This greenhouse features double roof vents, a lightning protection system on top of greenhouse ridge, motorized shade system and concrete stemwalls. Greenhouse butts up against headhouse and offices.

View of two earlier Phase I greenhouses with a central service corridor in background and newer Phase II gutter connected research greenhouse with two long research greenhouses sharing a central service corridor to foreground. These Nexus galvanized steel frame greenhouses are glazed with tempered single glass panes on pad and fan cooled cells and insulated glass on the air conditioned greenhouse cells.

Clear tempered glass on galvanized steel frame with concrete stemwalls. Note two slant wall Acme exhaust fans for each greenhouse cell.
stuttgart6[1]
Small gutter connected service corridor serving research greenhouses to both sides. Note roof vents are open on the service corridor to provide fresh air to the cooling pads on the corridor wall of each cell. You can see the motorized shutters open to allow air to reach the Koolcel pads in a cell visible through the windows on the double door at the south end of the corridor. Each greenhouse has lightning protection spikes down the greenhouse ridge and you can see the shadow caused by the slope/flat/slope motorized shade system in each greenhouse cell.

View down service corridor with research greenhouses to each side. Intake air for pad systems in each cell provided through roof vents overhead. Air then allowed into individual cells as needed through motorized shutters on both sidewalls that open when the Wadsworth control system in that cell calls for air or the more advanced stage of wetting the Koolcel pad system just inside the shutters for each cell. The water sump tank for each cell is visible in the corridor as are the controls and electric service panels for each cell.

Typical base plate for sidewall post on top of concrete stemwall. You can also see an exhaust fan penetrating through the glass wall and some of the high pressure sodium light fixtures hanging over the concrete floors where benches will be located just a few a days after this picture was taken.
