West Zone

Evidence homeGrowing Zones · Climate

West-specific layout and crop-placement notes stay here; shared zone climate panels and whole-house climate evidence live on the zone overview and climate pages.

The longest wall. Six shelf bays, 15 overhead 4FT grow lights on the rafters, and 15 shelf-level 2FT grow lights. The most versatile zone: not as hot as south, not as cool as east. No active production crop is assigned to this zone right now, so west uses default zone behavior until crop records are added.

Observed/Reference Zone

Does not count toward the current active-control crop total.

Current Control Crops

No occupied west-zone crop records in v_position_current.

Control Role

Uses default zone VPD behavior until a crop is assigned to west shelving.

Climate Profile

Metric	Value	Context
Temperature	Mid-range, hot late afternoon	Setting sun hits this wall directly
VPD	Mid-range	Between south (driest) and east (most humid)
Light	Strong natural + 30 grow lights	Best artificial light coverage
Afternoon peak	Takes over as hottest zone late PM	West-facing surfaces absorb afternoon sun

The Southwest Corner

The small angled southwest wall (~5-6 ft) has the best light transmission angle at 23.5%, the most perpendicular incidence of any surface. Two shelf bays here get the most efficient natural light delivery.

Physical Layout

Position	Contents	Grow Lights
WEST-SHELF-T1 through T6	6 shelf bays, top tier	15 Barrina 2FT lights (grow circuit, 12” OC)
WEST-SHELF-B1 through B6	6 shelf bays, bottom tier	15 Barrina 2FT lights (same circuit)
Rafters above	Overhead lighting	15 Barrina 4FT lights (main circuit, 36” OC, CRI 98)

Current contents: Physical pots and starts may be present, but no west crop records are active in v_position_current.

Wall Structure

At ~16-17 feet, the west wall is the longest continuous growing surface. Six shelf bays provide 12 total planting positions (6 top + 6 bottom). The overhead 4FT lights on the rafters are the highest-CRI fixtures in the greenhouse (CRI 98) and provide ambient supplemental light across the entire zone.

Shared drip circuit: Wall drip for south AND west is on one relay. Watering west waters south (and vice versa). Per-plant adjustment is via physical drip head volume restrictors only.

Mister configuration: West has overhead clean and fert mister paths. Current timing, wetting windows, and guardrails live in AI Tunables Traceability; equipment inventory lives on Equipment Inventory.

Current Plantings

No active crops

No occupied crop records are attached to West Greenhouse Zone.

Recommended Crops

Crop	Why West Zone	Notes
Basil	Warm enough, excellent grow light coverage	Good year-round
Cucumbers	Moderate heat, strong light, wall for vining	Trellis against wall
Mixed herbs (parsley, oregano, thyme)	Versatile conditions	Group by water needs
Garden starts	Moderate conditions, good light	For spring outdoor transplant
Peppers	Viable; less heat than south but sufficient	Most varieties do fine here

The west zone’s versatility makes it ideal for:

Mixed herb production (parsley, oregano, thyme, chives) on upper shelves
Garden starts for outdoor transplant (spring plan)
Overflow from the east zone when hydro positions are full
