What the AI looks for in Plant Lighting
- Efficacy
- Compare micromoles per joule (µmol/J). Good current horticultural LEDs are around 2.5 µmol/J or higher. Higher efficacy means more usable light per watt, with less heat and lower power use.
- PPFD for the plant
- Seedlings and leafy greens need low intensity, while fruiting and flowering plants need several times more. Check the manufacturer's PPFD map at your hanging height. Wattage alone doesn't tell you how much light reaches the canopy.
- Coverage uniformity
- The PPFD map should stay reasonably even out to the edges of your footprint. Hot centers and dim corners cause uneven growth.
- Spectrum
- Full-spectrum white light, often with added deep red, for growth through to flowering. White spectra make it easy to inspect plants, and red light supports flowering.
- Dimming and cooling
- Built-in dimmer, and passive heatsinks rather than fans where possible. Dimming lets one light serve seedlings and mature plants, and passive cooling is quiet and has nothing to fail.
Brands that matter
- Spider Farmer: Efficient, well-documented LED boards and bars.
- Mars Hydro: Budget-to-mid LED boards.
- AC Infinity: IONFRAME and IONBOARD lights that integrate with its controllers.
- Barrina: Low-cost T5-style strips for shelves and seedlings.
- Soltech Solutions: Decorative grow lights for houseplants.
- Gavita: Professional-grade horticultural lighting.
What to avoid
- Lights advertised by an 'equivalent watts' figure that is far above their actual power draw.
- Blurple (red-blue) budget panels with no published PPFD map.
- Clip-on gooseneck lights for anything beyond a single small houseplant.
- Lights with no stated efficacy or real wattage.
Questions
How high should I hang an LED grow light?
Follow the manufacturer's PPFD chart for your plant's stage. Hang it higher or dim it for seedlings, and lower it or turn it up for flowering, while watching for leaf bleaching.
