[Are you measuring in Lux? An app to learn the "unit of light" truly necessary for plant growth]
"I've installed plant growth lights, but I don't know how far away or for how many hours to shine them on..."
Are you struggling with this problem?
If you're measuring "Lux" using a smartphone light meter app and adjusting the lights accordingly, stop immediately!
🌿 Why is "Lux" unnecessary for plants?
"Lux" is merely a unit of "brightness perceived by the human eye."
While it strongly values ​​green light, which humans perceive as bright, it cannot accurately measure the "blue" and "red" light that plants most need for photosynthesis.
What's truly necessary for growing healthy and beautiful plants is not LUX, but "PPFD" and "DLI".
What is PPFD (Photon Quantum Flux Density)? It is the amount of light particles (photons) effective for photosynthesis that rain down on a plant's leaves per second. It varies greatly depending on the performance of the light and the "irradiation distance".
What is DLI (Daily Light Integral)? It is the "total amount of light a plant receives in one day". It is calculated by multiplying PPFD by the "irradiation time (day length)".
Even if you use a very strong light (high PPFD), if the irradiation time is short, the DLI will be insufficient, causing etiolation (stretching). Conversely, even with a weak light, if you expose the plant for a long time, you can ensure sufficient DLI for the plant.
This app, "DLI Calculator," is a specialized simulator that allows anyone to instantly and automatically calculate and determine the balance of this complex "PPFD, irradiation distance, irradiation time, and DLI".
✨ Main functions and features of "DLI Calculator"
1. Instantly and automatically calculate DLI from distance and PPFD
Simply input and slide the PPFD (or irradiation distance) of the light and the daily irradiation time to automatically calculate the "DLI," which is the total amount of light in one day. No complicated formulas are required. 2. Plant Database & Growth Stage (PLANTMILESTONE) Judgment
Includes standard data for over 18 types of plants, including agave, caudex plants, succulents, echeveria, and the popular "Platycerium (recommended DLI: 5-7 mol)."
Furthermore, by switching between the plant's growth stages [seedling stage, growth stage, flowering stage], it dynamically determines whether the plant is receiving the optimal DLI (light intensity) at that moment, categorized into three stages: "insufficient, appropriate, and light pollution risk."
3. Presets for Major Grow Lights
Includes distance attenuation data for "PLANTMILESTONE NEO," "ultra+," "PLANTS GLOW LIGHT," and other well-known grow lights as presets.
Simply select the light model and input the "irradiation distance" to the plant to instantly simulate the PPFD and DLI at that location.
4. Multiple Light Comparison Simulation
"Which is best for my agave, the light I currently have or the new light I want to buy?"
Such questions can be answered instantly with the multiple light comparison function. You can compare the performance and suitability for different plants at different light levels and illumination distances.

🎯 Recommended for:
Those who want to grow Agave (such as Titanota) into compact, high-quality plants without etiolation.
Those who want to provide the optimal light intensity for Platycerium (such as Ridleyi and Willinckii) to beautifully develop its spore-bearing leaves.
Those who want to prevent plants from dying due to excessive light during the seedling stage.
Those who want to optimize illumination time for efficient growth while keeping electricity costs down.
Those who are always struggling to determine the appropriate hanging height (illumination distance) for LED lights.
