If the collector typically sells 5 propagated plants per year at an average price of $500, a 25% increase translates to 1.25 additional plants sold, generating $625 in additional revenue.
* **Enhanced Coloration:** The improved coloration of the plants, resulting from the optimized light spectrum, increases their market value by an estimated 10%. This adds an additional $250 in value per plant sold (assuming an average sale price of $2500 for a high-value plant).
* **Reduced Losses:** The improved plant health and disease resistance, resulting from the optimized lighting, reduces plant losses by an estimated 5%. This translates to a savings of $125 per year (assuming an average plant value of $2500).
**Total Annual Benefits:** $625 (growth rate) + $250 (coloration) + $125 (reduced losses) = $1000
**ROI Calculation:**
* Annual ROI: ($1000 – $100) / $1500 = 60%
* Payback Period: $1500 / $900 = 1.67 years
This simplified calculation demonstrates that a professional grow light system can pay for itself in less than two years, while simultaneously enhancing the value and health of the plant collection.
