🌱 Introducing LumenSilo — The Third Free App in Leaftix’s Indoor Farming Trilogy

Leaftix is closing its trilogy of free grower‑focused tools with a powerful new release: LumenSilo , the lighting planner built specifically for indoor growers, vertical farms, and controlled‑environment agriculture.

After launching SproutPlan VPDSprout and MicroRack Architect , Leaftix is now delivering the final piece of the puzzle — a smart, intuitive, and science‑driven lighting planner that helps growers optimize DLI, PPFD, photoperiod, and energy costs with absolute clarity.

This is the third and final app in our series of free tools designed to empower indoor producers with enterprise‑grade technology, without the enterprise‑grade price tag.

💡 Meet LumenSilo: Your New Lighting Intelligence Hub

Lighting is the heartbeat of indoor cultivation — and often the most expensive part of running a grow room or vertical farm. LumenSilo was built to solve this challenge with precision.

Inside the app, growers can instantly calculate:

  • Daily Light Integral (DLI)
  • Optimal PPFD for each crop
  • Recommended photoperiod
  • Energy consumption (daily, monthly, yearly)
  • Real lighting cost projections
  • Rack and shelf lighting blueprints

Every calculation adapts to your real setup: number of racks, shelves, LED wattage, crop type, and local electricity rates. No spreadsheets. No guesswork. Just clarity.

🌿 Why LumenSilo Matters

Indoor growers constantly walk a tightrope between delivering enough light for strong growth and keeping energy costs under control. LumenSilo makes this balance effortless.

With real‑time modeling, you can see exactly how adjusting your photoperiod or LED power affects:

  • your final DLI,
  • your crop’s biological needs,
  • your monthly and annual energy bill.

It’s like having a lighting consultant built directly into your browser — and it’s free.

🧠 Key Features

  • Science‑based DLI ranges for each crop
  • Instant rack modeling and power adjustments
  • Accurate cost projections based on your local rates
  • Saved blueprints for multiple crops
  • Clean, intuitive interface designed for growers
  • 100% free — no subscription, no paywall

🚀 Completing the Trilogy

LumenSilo is the final chapter in Leaftix’s three‑app series created to support indoor growers with accessible, high‑impact tools:

  1. SproutPlanner — rack layout optimization
  2. VPDSprout — environmental planning
  3. LumenSilo — lighting intelligence and cost planning

And all three are free.
