Method & Assumptions

This is an educational planning tool designed for homeowners. It uses simple, transparent math with conservative defaults that you can adjust to match your real garden conditions.

  • Annual delivered pounds = (tubes × plants/tube × survival) × (yield/plant/cycle) × cycles × efficiency × sun factor × (waste factor).
  • Servings = delivered pounds × servings per pound (default 3).
  • Coverage days = annual servings ÷ (household people × recommended servings/day).
  • Water saved = (traditional − Root Tube) × (plants adjusted) × cycles.
  • Savings = min(value of produce grown, your annual produce spend).
Score weights: Food coverage 30%, Water 25%, Economic savings 25%, Sustainability 20%.
