Workflow
Calculate Chiller BTU and Ventilation CFM
Half daySum heat load from stacked lights, size chiller for sensible heat removal, calculate total exhaust CFM for CO2 and humidity.
Size Clone Domes and Prop Tier
1 dayCalculate humidity dome volume for weekly clone count, PAR for clone stage, and transition timing to veg tiers.
Operate Multi-Tier Harvest Pipeline
OngoingStagger tiers for weekly harvest, track power cost per tier, monitor root zone temp on each NFT level.

Vertical Farm Tier PlanningTable
Vertical Farm Tier Planning
| Tier | Crop Stage | PAR Target |
|---|---|---|
| Bottom | Harvest ready | 200–400 |
| Middle | Vegetative | 400–600 |
| Top | Seedling/clone | 200–300 |
| Prop | Clone | 100–200 |
Stacked Heat LoadFormula
Total BTU ≈ sum(fixture watts × 3.412) + ambient infiltration − vented heat recovery.
Tier Access SafetyStandard
Secure ladders and platforms for top-tier maintenance — do not overreach from lower levels.
Stabilize pH First
Adjust pH before adding nutrients — pH drift after mixing wastes expensive inputs.
Root Zone Temp
Keep reservoir 65–70°F — warmer water holds less oxygen and invites root rot.
Electrical Safety
Drip loops on all cords entering reservoirs and GFCI on every outlet.
Safety Notes
- Keep electrical components away from water — use GFCI outlets for all pumps and lights.
- Monitor pH and nutrient levels daily — imbalances kill plants quickly.
