How the Light Recommendation Calculator Works
The Light Recommendation Calculator helps you determine the optimal lighting setup and operating costs for your grow space. Here’s an overview of each section:
- Space Dimensions: Enter the width and length of your grow area in feet. This calculates the total coverage area, helping determine the number of lights needed.
- Target PPFD Level: Choose the desired PPFD (Photosynthetic Photon Flux Density) level for your plants, depending on CO₂ levels and light requirements.
- Electricity Rate: Enter the cost per kWh for your area. This lets the calculator estimate monthly and yearly energy expenses.
- Light Cycle: Select the number of hours the lights will be on daily. This is used to compute the operating time and costs.
- Cost per Light: Enter the cost per light fixture. This is factored into the total cost, including upfront and ongoing costs over 1, 3, and 5 years.
Based on these inputs, the calculator recommends the number of 600W and 1000W lights needed, as well as their total operating costs.
Advanced Grow Light Layout Calculator
This tool is being rebuilt around verified, height-specific PPFD maps and physical row-by-column layouts. It is intentionally not issuing fixture-count, hotspot, mounting-height, or uniformity recommendations yet.
The DLI and electricity calculators remain available while the advanced model is validated.
Step-by-Step Guide to Using the Calculator
- Gather Required Information: Measure your grow area and decide on your target PPFD level and light cycle. Know your electricity rate and the cost of your lighting fixtures.
- Enter Grow Area Details: Input the width and length of your grow area to calculate the total space.
- Select PPFD Level and Light Cycle: Choose your target PPFD level based on your growth goals and CO₂ environment. Then select the light cycle duration.
- Enter Equipment Cost and Energy Rate: Enter the price per light and electricity rate (cents per kWh) for accurate cost projections.
- Calculate Recommendation: Press “Calculate Recommendation” to receive details on recommended light fixtures, total energy usage, and cost estimates.
