🌱 Underground Vertical Farms

Interactive 3D underground vertical farm: tune LED PPFD, photoperiod, rack tiers and electricity price and watch energy load, water recirculation and payback economics respond live.

A tunnel-style underground vertical farm cutaway with stacked LED-lit crop racks and a closed-loop nutrient water system, driven by real lighting-energy and payback-economics formulas.

🔬 What It Demonstrates

LED wattage scales with target PPFD and rack tier count, driving daily kWh and cost; photoperiod compresses a full day into a short visual cycle so you can watch racks switch on and off; water recirculation toggles between closed-loop and single-pass water use.

🎮 How to Use

Adjust PPFD, photoperiod, tier count and electricity price to see the LED load, daily energy cost and estimated payback period update live. Toggle the closed-loop water system to compare recirculated vs. single-pass water reuse.

💡 Did You Know?

Because there is no sunlight underground, every micromole of light a plant receives is metered electricity — which is why lighting efficacy (µmol per joule) matters as much to a vertical farm's balance sheet as crop yield itself.
