Lighting โ FAQ
What does 'full spectrum' actually mean for grow lights?
Full spectrum means the light emits wavelengths across the entire photosynthetic range (400-700nm), including visible white light plus targeted red and blue LEDs. This mimics natural sunlight and supports all growth stages from seedling to flowering.
How far should grow lights be from plant leaves?
Position lights 6-12 inches from most plants. Seedlings and delicate herbs need 12-18 inches to prevent scorching, while mature fruiting plants can handle 4-6 inches for maximum intensity. Always start farther and move closer if leaves show no stress.
How many hours per day should I run my grow light?
Most foliage plants thrive with 12-14 hours. Flowering and fruiting plants need 14-16 hours. Succulents and cacti do well with 10-12 hours. Use the built-in timer to maintain consistent daily cycles โ irregular lighting stresses plants.
Are LED grow lights better than fluorescent tubes?
Modern LEDs outperform fluorescents in efficiency, lifespan, and spectrum control. LEDs produce 2-3x more light per watt, last 50,000+ hours versus 10,000, and run cooler. The upfront cost is higher, but energy savings recover the difference within 18 months.
Can I use one grow light for all my indoor plants?
Yes, if you choose a full-spectrum model with adjustable height and brightness. Position light-loving plants like tomatoes directly underneath, and shade-tolerant plants like pothos at the periphery. Rotate plants weekly for even exposure.
Do grow lights consume a lot of electricity?
A typical 40-watt LED grow light costs $2-4 monthly running 12 hours daily at average electricity rates. That's less than a single cafรฉ latte. LEDs are 70% more efficient than old incandescent plant bulbs and produce far less waste heat.
