What's the difference between LED and HPS grow lights?

LED lights are energy-efficient, run cooler, and last longer, making them better for most home growers. HPS lights are cheaper upfront but consume more power and generate heat, so you'll need ventilation and spend more on electricity over time.

How do I know what wattage I need for my growing space?

A general rule is 30-50 watts per square foot, so measure your grow area and multiply. For example, a 2x2 foot space needs 120-200 watts, while a 4x4 foot space needs 480-800 watts.

What's the difference between full spectrum and specific color temperatures?

Full spectrum lights mimic natural sunlight and work for all growth stages, while blue lights promote vegetative growth and red lights trigger flowering. Most serious growers prefer full spectrum LED fixtures for simplicity and consistent results.

When is it worth spending more on a premium grow light?

Higher-end fixtures offer better efficiency (more light per watt), superior heat management, and longer warranties—worth it if you're growing year-round or in a commercial setup. For casual growers with one small space, a mid-range LED light delivers good results without the premium cost.

How close should the grow light be to my plants?

Most LED lights should sit 12-24 inches above plants, but check your fixture's manual since different models vary. Too close causes light burn, while too far reduces effectiveness and slows growth.
