FAQ
Grow light bulbs provide the specific light spectrum and intensity plants need for healthy growth, regardless of natural sunlight availability. They help optimize yields and support all growth stages.
Consider your grow space size, the type of plants, and the growth stage. Double-ended HPS bulbs are ideal for flowering, while metal halide and compact fluorescents suit vegetative growth and propagation.
Grow light fixtures are designed for specific bulb types and wattages. Always check fixture and bulb compatibility before installation to ensure safety and optimal performance.
Replacement frequency depends on the bulb type and usage. Double-ended HPS and metal halide bulbs often last longer, but it’s best to monitor light output and replace bulbs when intensity drops.
Some bulbs, like dual arc lamps, are designed for full-cycle use, while others are optimized for either vegetative or flowering stages. Review product specifications to match your growing needs.
Always turn off power before installation, use the correct wattage and fixture, and avoid touching bulbs with bare hands to prevent damage. Follow manufacturer guidelines for best results.
