FAQs

How many watts do I need for my grow space?

The wattage depends on the size of your grow tent or room. A general guideline is 30-50 watts per square foot for high-light plants. For example, a 2x2 ft area may need 100-200W, while a 4x4 ft area may require 400-600W for optimal coverage.

What is the difference between full-spectrum and red/blue LED grow lights?

Full-spectrum LED lights mimic natural sunlight, providing a balanced mix of blue (for vegetative growth) and red (for flowering and fruiting) light. Red/blue LED lights focus on specific wavelengths but may not support plants as effectively as full-spectrum lights.

Does GrowPros offer energy rebates for its products?

Yes! The potential savings from energy rebates are substantial, often covering approximately 50-75% of the overall project cost. To get a personalized estimate of your potential savings, simply contact us and we'll provide a complimentary assessment tailored to your project.

How much energy can I save with GrowPros' energy-efficient lights?

Upgrading to LEDs can cut your energy use by up to 75% compared to old-school incandescent bulbs and around 40% less than HID lights. That means lower electricity bills, especially if you're running multiple fixtures. Plus, LEDs last way longer, so you’ll save even more on replacements and energy costs over time.

Can GrowPros LED lights be customized for different bud strains?

Absolutely! We offer customizable spectrums and intensities to match the specific needs of different strains. Our tailored lighting solutions help optimize growth, potency, and terpene profiles.
