Example: Vertical Farm Setup

Complete workflow for setting up and operating a vertical farm with LocalGreenChain.

Scenario

You're setting up a 400 sqm vertical farm to grow lettuce, basil, and microgreens year-round.

Step 1: Register Your Farm

// POST /api/vertical-farm/register

const farmRegistration = {
  name: 'Urban Greens VF',
  ownerId: 'operator-001',

  location: {
    latitude: 40.7128,
    longitude: -74.0060,
    address: '500 Industrial Way',
    city: 'Brooklyn',
    country: 'USA',
    timezone: 'America/New_York'
  },

  specs: {
    totalAreaSqm: 500,
    growingAreaSqm: 400,
    numberOfLevels: 4,
    ceilingHeightM: 4,
    totalGrowingPositions: 5000,
    currentActivePlants: 0,
    powerCapacityKw: 150,
    waterStorageL: 10000,
    backupPowerHours: 24,
    certifications: ['gap', 'local_food_safety'],
    buildingType: 'warehouse',
    insulation: 'high_efficiency'
  },

  automationLevel: 'semi_automated'
};

const response = await fetch('/api/vertical-farm/register', {
  method: 'POST',
  headers: { 'Content-Type': 'application/json' },
  body: JSON.stringify(farmRegistration)
});

const { data: farm } = await response.json();
console.log('Farm registered:', farm.id);
console.log('Status:', farm.status);  // 'operational'

Step 2: Configure Growing Zones

Create zones for different crops:

// Zone A: Lettuce (NFT system)
const zoneA = {
  name: 'Zone A - Lettuce',
  level: 1,
  areaSqm: 150,
  lengthM: 30,
  widthM: 5,
  growingMethod: 'NFT',
  plantPositions: 1800,

  environmentTargets: {
    temperatureC: { min: 18, max: 24, target: 21 },
    humidityPercent: { min: 55, max: 75, target: 65 },
    co2Ppm: { min: 800, max: 1400, target: 1000 },
    lightPpfd: { min: 200, max: 400, target: 300 },
    lightHours: 16,
    nutrientEc: { min: 1.2, max: 1.8, target: 1.5 },
    nutrientPh: { min: 5.5, max: 6.5, target: 6.0 },
    waterTempC: { min: 18, max: 22, target: 20 }
  }
};

// Zone B: Basil (DWC system)
const zoneB = {
  name: 'Zone B - Basil',
  level: 2,
  areaSqm: 100,
  lengthM: 20,
  widthM: 5,
  growingMethod: 'DWC',
  plantPositions: 1200,

  environmentTargets: {
    temperatureC: { min: 20, max: 28, target: 24 },
    humidityPercent: { min: 50, max: 70, target: 60 },
    co2Ppm: { min: 800, max: 1400, target: 1200 },
    lightPpfd: { min: 300, max: 500, target: 400 },
    lightHours: 18,
    nutrientEc: { min: 1.0, max: 1.6, target: 1.3 },
    nutrientPh: { min: 5.5, max: 6.5, target: 6.0 },
    waterTempC: { min: 18, max: 22, target: 20 }
  }
};

// Zone C: Microgreens (Rack system)
const zoneC = {
  name: 'Zone C - Microgreens',
  level: 3,
  areaSqm: 100,
  lengthM: 20,
  widthM: 5,
  growingMethod: 'rack_system',
  plantPositions: 2000,  // Tray positions

  environmentTargets: {
    temperatureC: { min: 18, max: 24, target: 21 },
    humidityPercent: { min: 60, max: 80, target: 70 },
    co2Ppm: { min: 600, max: 1200, target: 800 },
    lightPpfd: { min: 150, max: 300, target: 250 },
    lightHours: 16,
    nutrientEc: { min: 0.5, max: 1.0, target: 0.8 },
    nutrientPh: { min: 5.5, max: 6.5, target: 6.0 },
    waterTempC: { min: 18, max: 22, target: 20 }
  }
};

// Create zones
for (const zone of [zoneA, zoneB, zoneC]) {
  await fetch(`/api/vertical-farm/${farm.id}/zones`, {
    method: 'POST',
    headers: { 'Content-Type': 'application/json' },
    body: JSON.stringify(zone)
  });
}

console.log('Zones configured: Lettuce, Basil, Microgreens');

Step 3: View Available Recipes

// GET /api/vertical-farm/recipes

const response = await fetch('/api/vertical-farm/recipes');
const { data: recipes } = await response.json();

console.log('Available recipes:');
for (const recipe of recipes) {
  console.log(`- ${recipe.name}`);
  console.log(`  Crop: ${recipe.cropType}`);
  console.log(`  Days: ${recipe.expectedDays}`);
  console.log(`  Yield: ${recipe.expectedYieldGrams}g per plant`);
}

/*
Available recipes:
- Butterhead Lettuce - Fast Cycle
  Crop: lettuce
  Days: 35
  Yield: 180g per plant

- Genovese Basil - Aromatic
  Crop: basil
  Days: 42
  Yield: 120g per plant

- Microgreens Mix - Quick Turn
  Crop: microgreens
  Days: 14
  Yield: 200g per tray
*/

Step 4: Start Crop Batches

Link to Seed Source

First, ensure seeds are tracked in the transport chain:

// Record seed acquisition (see seed-to-harvest example)
await fetch('/api/transport/seed-acquisition', {
  method: 'POST',
  body: JSON.stringify({
    seedBatchId: 'seeds-lettuce-vf-001',
    sourceType: 'purchase',
    species: 'Lactuca sativa',
    quantity: 10000,
    quantityUnit: 'seeds',
    // ... other fields
  })
});

Start Lettuce Batch

// POST /api/vertical-farm/batch/start

const lettuceBatch = {
  farmId: farm.id,
  zoneId: 'zone-a-id',
  recipeId: 'recipe-lettuce-butterhead',
  seedBatchId: 'seeds-lettuce-vf-001',  // Links to transport chain!
  plantCount: 200
};

const response = await fetch('/api/vertical-farm/batch/start', {
  method: 'POST',
  headers: { 'Content-Type': 'application/json' },
  body: JSON.stringify(lettuceBatch)
});

const { data: batch } = await response.json();

console.log('Batch started:', batch.id);
console.log('Expected harvest:', batch.expectedHarvestDate);
console.log('Expected yield:', batch.expectedYieldKg, 'kg');
console.log('Plant IDs:', batch.plantIds.length, 'plants tracked');

/*
Batch started: batch-lettuce-001
Expected harvest: 2024-07-06
Expected yield: 36 kg
Plant IDs: 200 plants tracked
*/

Start Microgreens Batch

const microgreensBatch = {
  farmId: farm.id,
  zoneId: 'zone-c-id',
  recipeId: 'recipe-microgreens-mix',
  seedBatchId: 'seeds-microgreens-001',
  plantCount: 50  // 50 trays
};

await fetch('/api/vertical-farm/batch/start', {
  method: 'POST',
  body: JSON.stringify(microgreensBatch)
});

// Microgreens harvest in just 14 days!

Step 5: Report Environment Data

Set up automated reporting from your control system:

// Environmental monitoring script

async function reportEnvironment() {
  // Collect sensor data
  const readings = await collectSensorData('zone-a-id');

  // PUT /api/vertical-farm/batch/{batchId}/environment
  const response = await fetch(`/api/vertical-farm/batch/${batch.id}/environment`, {
    method: 'PUT',
    headers: {
      'Content-Type': 'application/json',
      'Authorization': `Bearer ${API_KEY}`
    },
    body: JSON.stringify({
      timestamp: new Date().toISOString(),
      temperatureC: readings.temperature,      // 21.5
      humidityPercent: readings.humidity,      // 68
      co2Ppm: readings.co2,                    // 1050
      vpd: readings.vpd,                       // 0.85
      ppfd: readings.ppfd,                     // 295
      dli: readings.dli,                       // 17.0
      waterTempC: readings.waterTemp,          // 19.5
      ec: readings.ec,                         // 1.55
      ph: readings.ph,                         // 6.1
      dissolvedOxygenPpm: readings.do,         // 8.2
      airflowMs: readings.airflow              // 0.5
    })
  });

  const { data } = await response.json();

  // Handle any alerts
  if (data.alerts && data.alerts.length > 0) {
    console.log('ALERTS:', data.alerts);
    for (const alert of data.alerts) {
      handleAlert(alert);
    }
  }

  console.log('Environment recorded. Health score:', data.healthScore);
}

// Report every 5 minutes
setInterval(reportEnvironment, 5 * 60 * 1000);

Step 6: Monitor Batch Progress

// Check batch status daily

async function checkBatchProgress(batchId: string) {
  // GET /api/vertical-farm/batch/{batchId}
  const response = await fetch(`/api/vertical-farm/batch/${batchId}`);
  const { data: batch } = await response.json();

  console.log(`
Batch: ${batch.id}
Crop: ${batch.cropType}
Day: ${batch.currentDay} / ${batch.expectedDays}
Stage: ${batch.currentStage}
Health: ${batch.healthScore}%
Status: ${batch.status}
Expected Harvest: ${batch.expectedHarvestDate}
  `);

  // Check for issues
  if (batch.issues.length > 0) {
    console.log('ISSUES:');
    for (const issue of batch.issues) {
      console.log(`- ${issue.type}: ${issue.description}`);
    }
  }

  // Approaching harvest?
  const daysToHarvest = batch.expectedDays - batch.currentDay;
  if (daysToHarvest <= 3) {
    console.log('ALERT: Prepare for harvest in', daysToHarvest, 'days');
  }

  return batch;
}

Step 7: Complete Harvest

// POST /api/vertical-farm/batch/{batchId}/harvest

const harvestData = {
  actualYieldKg: 38.5,  // Exceeded expectation!
  qualityGrade: 'A',
  notes: 'Excellent crop. Slight overperformance due to optimal conditions.'
};

const response = await fetch(`/api/vertical-farm/batch/${batch.id}/harvest`, {
  method: 'POST',
  headers: { 'Content-Type': 'application/json' },
  body: JSON.stringify(harvestData)
});

const { data: harvestResult } = await response.json();

console.log('Harvest completed!');
console.log('Actual yield:', harvestResult.actualYieldKg, 'kg');
console.log('Expected yield:', harvestResult.expectedYieldKg, 'kg');
console.log('Variance:', harvestResult.yieldVariance, '%');
console.log('Quality grade:', harvestResult.qualityGrade);

/*
This automatically:
1. Records harvest in transport chain
2. Links to seed origin (full traceability)
3. Updates batch status to 'completed'
4. Frees zone for next batch
*/

Step 8: View Analytics

// GET /api/vertical-farm/{farmId}/analytics?period=30

const response = await fetch(
  `/api/vertical-farm/${farm.id}/analytics?period=30`
);
const { data: analytics } = await response.json();

console.log(`
=== FARM ANALYTICS (30 days) ===

Complete Setup Script

// vertical-farm-setup.ts

import { getVerticalFarmController } from '@/lib/vertical-farming/controller';

async function setupVerticalFarm() {
  const controller = getVerticalFarmController();

  // 1. Register farm
  const farm = await registerFarm();
  console.log('Farm registered:', farm.id);

  // 2. Configure zones
  const zones = await configureZones(farm.id);
  console.log('Zones configured:', zones.length);

  // 3. View recipes
  const recipes = controller.getRecipes();
  console.log('Available recipes:', recipes.length);

  // 4. Start batches for each zone
  const batches = [];
  for (const zone of zones) {
    const recipe = selectRecipeForZone(zone, recipes);
    const batch = controller.startCropBatch(
      farm.id,
      zone.id,
      recipe.id,
      `seeds-${recipe.cropType}-001`,
      calculatePlantCount(zone, recipe)
    );
    batches.push(batch);
    console.log(`Started ${recipe.cropType} in ${zone.name}`);
  }

  // 5. Set up monitoring
  setupEnvironmentMonitoring(batches);

  // 6. Schedule harvest checks
  scheduleHarvestAlerts(batches);

  return { farm, zones, batches };
}

// Run setup
setupVerticalFarm()
  .then(({ farm, zones, batches }) => {
    console.log('\n=== SETUP COMPLETE ===');
    console.log(`Farm: ${farm.name}`);
    console.log(`Zones: ${zones.length}`);
    console.log(`Active batches: ${batches.length}`);
  })
  .catch(console.error);

Production Schedule

With continuous operation:

Week 1: Start lettuce batch A (200 plants)
Week 2: Start microgreens batch A (50 trays), basil batch A (150 plants)
Week 3: Harvest microgreens A, start microgreens B
Week 4: Harvest microgreens B, start microgreens C
Week 5: Harvest lettuce A, start lettuce B
