Technology · The method in detail

A farm built on data, not luck.

Three systems working together — hydroponic cultivation, sensor-driven environment control, and a solar & rainwater sustainability layer.

How it works

Less cutting‑edge.
More measured every six minutes.

Inside the Arrow Fresh greenhouse, every variable that affects a crop — light, temperature, humidity, root-zone pH, nutrient electrical conductivity — is sampled every six minutes and adjusted automatically. We're not farming with the weather. We're farming past it.

The result is produce that doesn't know what season it is. Basil in July looks like basil in January. Lettuce harvest weight varies by less than 8% across an entire production year. For a buyer planning a menu twelve weeks out, that consistency is the whole product.

Cultivation

Hydroponic, soil-free.

We grow in coconut-coir media — a renewable byproduct of the coconut industry — fed by a recirculating nutrient solution that delivers exactly the macros and micros each crop needs at each growth stage.

The roots see clean water, balanced electrical conductivity, and a stable pH between 5.8 and 6.2. Soil-based farming — the dominant practice in Pakistan — can't credibly promise any of those.

  • MediaCocopeat slabs, replaced every three crop cycles.
  • SolutionRecirculating; replenished daily, fully replaced weekly.
  • pH range5.8–6.2 (target); deviation triggers automated correction.
  • EC range1.4–2.6 mS/cm depending on crop and growth stage.

Control

Sensor-monitored, end to end.

Sensor networks monitor temperature, humidity, CO₂, light intensity and root-zone conditions every six minutes across the production floor.

A central control loop adjusts shade screens, ventilation fans, irrigation cycles and supplemental LEDs in real time. The greenhouse responds before a human would notice anything is wrong.

  • Sample rateEvery 6 minutes, all variables.
  • ActuationShade screens · fans · irrigation · LED grow lights.
  • AlarmsSMS to on-call agronomist on out-of-band readings.
  • Data retentionFull sensor log archived for 5 years.

Sustainability

Solar-run, rain-fed.

Rooftop photovoltaics generate the operational electricity, March through November. Harvested monsoon water — filtered, balanced, and stored in lined reservoirs — runs the irrigation system year-round.

The result is a greenhouse that is grid-independent for nine months of the year and draws roughly a tenth of the water of equivalent open-field cultivation.

  • Solar100% of operational electricity, Mar–Nov.
  • WaterRainwater harvested + filtered; 90% reduction vs. open-field.
  • WasteSpent coco-coir composted; nutrient solution polished & reused.
  • IPMBiological controls only; zero pesticide application on record.
Sustainability, audited

What hydroponics actually saves.

Conservative figures, applicable to our greenhouse specifically — not the marketing brochure version of the technology. Audited annually.

~90%

Less water.

Recirculating, closed-loop irrigation vs. open-field cultivation of the same crop.

30–50%

Faster growth cycles.

Median reduction across leafy greens; controlled-environment compounding.

100%

Solar-powered.

Operational electricity from rooftop photovoltaics, March through November.

Hydroponic vs traditional

The difference, on paper.

Side-by-side, our practice vs. the open-field cultivation that most Pakistani produce still comes from. Conservative numbers; audited annually.
