West Zone

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. Currently holds propagation trays, house plants, and rotating experimental plantings. No active production crop is assigned to this zone, so its VPD target defaults to 1.20 kPa.
Observed/Reference Zone

Does not count toward the launch 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.

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.

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: 3 active heads (3 off β€” over storage below). 15 active nozzles. Overhead-mounted. VPD drop effectiveness: 0.13 kPa per pulse (second best after south’s 0.15).

CropWhy West ZoneNotes
BasilWarm enough, excellent grow light coverageGood year-round
CucumbersModerate heat, strong light, wall for viningTrellis against wall
Mixed herbs (parsley, oregano, thyme)Versatile conditionsGroup by water needs
Garden startsModerate conditions, good lightFor spring outdoor transplant
PeppersViable; less heat than south but sufficientMost 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
